Der Erfindung liegt die Aufgabe zugrunde, ein, insbesondere im Hinblick auf die Herstellung eines Garns mit verbesserten Eigenschaften, verbessertes Verfahren zur Herstellung eines Garns anzugeben.The invention is based on the object of specifying an improved method for producing a yarn, in particular with regard to the production of a yarn with improved properties.

Die Aufgabe wird durch ein Verfahren gemäß Anspruch 1 gelöst. Die hierzu abhängigen Ansprüche betreffen mögliche Ausführungsformen des Verfahrens.The object is achieved by a method according to claim 1. The claims dependent on this relate to possible embodiments of the method.

Das hierin beschriebene Verfahren dient im Allgemeinen zur Herstellung wenigstens eines Garns. Selbstverständlich lassen sich mit dem Verfahren in entsprechender Weise auch mehrere Garne herstellen.The method described herein generally serves to produce at least one yarn. Of course, several yarns can also be produced in a corresponding manner using the method.

Das Verfahren umfasst drei wesentliche Schritte, welche im Folgenden näher erläutert werden.The process comprises three main steps, which are explained in more detail below.

In einem ersten Schritt des Verfahrens erfolgt ein Bereitstellen von wenigstens zwei zur Ausbildung des herzustellenden Garns miteinander zu verspinnenden einzelnen Fasern. Bei den Fasern kann es sich z. B. um Stapelfasern handeln. Die Fasern können auch als Roving bzw. Vorgarn bezeichnet bzw. erachtet werden. Wenn hierin von einer "Faser" die Rede ist, kann hierunter sonach ein Roving bzw. Vorgarn verstanden werden. Die Fasern können jeweils über einen Faservorrat, wie z. B. eine Faserspule, von welcher eine im Rahmen des Verfahrens zu einem Garn zu verspinnende Faser abgewickelt wird, bereitgestellt werden. Die Anzahl der Faservorräte bestimmt sich typischerweise nach der Anzahl der verfahrensgemäß zu einem Garn zu verspinnenden Fasern.In a first step of the method, at least two individual fibers to be spun together to form the yarn to be produced are provided. The fibers can be z. B. are staple fibers. The fibers can also be referred to or considered as roving or roving. If a "fiber" is mentioned here, it can therefore be understood as meaning a roving or roving. The fibers can each have a fiber supply, such as. B. a fiber spool, from which a fiber to be spun into a yarn within the scope of the method is unwound. The number of fiber stocks is typically determined by the number of fibers to be spun into a yarn according to the process.

In einem zweiten Schritt des Verfahrens erfolgt ein Zuführen der wenigstens zwei bereitgestellten Fasern zu einer wenigstens ein Spindel- bzw. Spulenelement umfassenden Spinneinrichtung über eine mehrere Führungselemente umfassende Führungseinrichtung. In dem zweiten Schritt des Verfahrens werden die zu dem Garn zu verspinnenden Fasern sonach über eine Führungseinrichtung einer Spinneinrichtung zugeführt. Die Führungseinrichtung umfasst typischerweise mehrere Führungselemente. Die Führungselemente sind typischerweise in Faserführungsrichtung hintereinander geschaltet angeordnet, sodass eine zu führende Faser von einem ersten Führungselement auf ein diesem in Faserführungsrichtung nachgeschaltet angeordnetes weiteres Führungselement geführt werden kann. Ein in Faserführungsrichtung erstes Führungselement der Führungseinrichtung ist den jeweiligen Faservorräten in Faserführungsrichtung unmittelbar nachgeschaltet angeordnet, ein in Faserführungsrichtung letztes Führungselement ist der Spinneinrichtung in Faserführungsrichtung unmittelbar vorgeschaltet angeordnet. Zwischen in Faserführungsrichtung (unmittelbar) aufeinanderfolgend, gleichwohl in Faserführungsrichtung beabstandet angeordneten Führungselementen können geeignete, z. B. plattenartige bzw. - förmige, Stützelemente vorgesehen werden, welche eine gewünschte Stützwirkung auf die zu führenden Fasern ausüben. Entsprechende Stützelemente können z. B. auch zwischen dem ersten Führungselement und den Faservorräten angeordnet sein.In a second step of the method, the at least two fibers provided are fed to a spinning device comprising at least one spindle or bobbin element via a guide device comprising a plurality of guide elements. In the second step of the process, the fibers to be spun into the yarn are then fed to a spinning device via a guide device. The guide device typically includes a number of guide elements. The guide elements are typically arranged one behind the other in the fiber guide direction, so that a fiber to be guided can be guided from a first guide element to a further guide element arranged downstream of this in the fiber guide direction. A first guide element of the guide device in the fiber guide direction is arranged immediately downstream of the respective fiber stores in the fiber guide direction, a last guide element in the fiber guide direction is arranged directly upstream of the spinning device in the fiber guide direction. between in Fiber guidance direction (immediately) successively, although spaced apart in the fiber guidance direction guide elements can be suitable, z. B. plate-like or - shaped, supporting elements are provided, which exert a desired supporting effect on the fibers to be guided. Corresponding support elements can, for. B. also be arranged between the first guide element and the fiber stocks.

Jeweilige Führungselemente weisen typischerweise eine zylinderartige bzw. -förmige geometrische Gestalt bzw. Grundform auf; die Führungselemente können sonach als Führungsrollen bzw. -walzen bzw. -zylinder bezeichnet bzw. erachtet werden. Jeweilige zylinderartige bzw. -förmige Führungselemente sind typischerweise um ihre Symmetrie- bzw. Zentralachse drehbar gelagert, sodass sich durch Drehbewegungen der Führungselemente um ihre jeweilige Symmetrie- bzw. Zentralachse eine geführte Bewegung der zu führenden Fasern in Richtung der Spinneinrichtung ermöglichen lässt.Respective guide elements typically have a cylindrical or -shaped geometric shape or basic shape; the guide elements can thus be referred to or considered as guide rollers or rollers or cylinders. Each cylinder-like or cylinder-shaped guide element is typically mounted so that it can rotate about its axis of symmetry or central axis, so that a guided movement of the fibers to be guided in the direction of the spinning device can be made possible by rotary movements of the guide elements about their respective axis of symmetry or central axis.

Einzelne, mehrere oder sämtliche Führungselemente können mit einer bestimmten, z. B. durch eine Gummierung realisierten, Haft(ober)fläche versehen sein, welche aufgrund einer auf die Fasern ausgeübten Haftwirkung eine gewünschte Führung der Fasern ermöglicht, d. h. insbesondere ein bezüglich der Faserführungsrichtung unerwünschtes seitliches Verrutschen der Fasern erschwert bzw. verhindert.Individual, several or all guide elements can be provided with a specific, e.g. B. realized by a rubber coating, be provided adhesive (upper) surface, which allows a desired guidance of the fibers due to an adhesive effect exerted on the fibers, d. H. in particular, a lateral slipping of the fibers which is undesirable with respect to the direction of fiber guidance is made more difficult or prevented.

In einem dritten Schritt des Verfahrens erfolgt ein Verspinnen der der Spinneinrichtung zugeführten Fasern in der Spinneinrichtung unter Ausbildung des herzustellenden Garns. Das Verspinnen der Fasern zur Ausbildung des herzustellenden Garns erfolgt typischerweise in einem sich an das letzte Führungselement anschließenden Spinnbereich. Die Spinneinrichtung umfasst wenigstens ein Spindel- oder Spulenelement, auf welches die miteinander versponnenen Fasern bzw. das durch Verspinnen der Fasern ausgebildete Garn aufgewickelt werden bzw. wird. Bei einem Spindel- bzw. Spulenelement kann es sich um eine Bobine bzw. Kopse handeln. Die Anzahl der Spindel- bzw. Spulenelemente bzw. die sich hieraus ergebende Anzahl der Spinnbereiche bestimmt sich nach der Anzahl der herzustellenden Garne.In a third step of the method, the fibers fed to the spinning device are spun in the spinning device, forming the yarn to be produced. The spinning of the fibers to form the yarn to be produced typically takes place in a spinning area that follows the last guide element. The spinning device comprises at least one spindle or spool element onto which the fibers spun together or the yarn formed by spinning the fibers are or will be wound. A spindle or coil element can be a bobbin or cops. The number of spindle or bobbin elements or the resulting number of spinning areas is determined by the number of yarns to be produced.

Verfahrensgemäß werden die wenigstens zwei zu einem Garn zu verspinnenden Fasern der Spinneinrichtung im Gegensatz zu konventionellen Verfahren nicht über ein (gemeinsames) Führungselement, sondern über wenigstens zwei separate, in wenigstens einer Raumrichtung räumlich beabstandet voneinander angeordnete, insbesondere zylinderartige bzw. -förmige, Führungselemente zugeführt. Mit anderen Worten wird eine erste zur Ausbildung des herzustellenden Garns zu verspinnende Faser der Spinneinrichtung über ein erstes Führungselement zugeführt wird und eine mit der ersten Faser zur Ausbildung des herzustellenden Garns zu verspinnende zweite Faser der Spinneinrichtung über ein zu dem ersten Führungselement in wenigstens einer Raumrichtung beabstandet angeordnetes zweites Führungselement zugeführt.According to the method, the at least two fibers to be spun into a yarn are fed to the spinning device, in contrast to conventional methods, not via a (common) guide element, but via at least two separate, in particular cylindrical or cylinder-shaped, guide elements arranged at a distance from one another in at least one spatial direction . In other words, a first fiber to be spun to form the yarn to be produced is fed to the spinning device via a first guide element and one with the first fiber to form the second fiber to be spun of the yarn to be produced is fed to the spinning device via a second guide element arranged at a distance from the first guide element in at least one spatial direction.

Mithin wird im Rahmen des Verfahrens eine Führungseinrichtung verwendet, welche wenigstens zwei separate, in wenigstens einer Raumrichtung räumlich beabstandet voneinander angeordnete, zylinderartige oder -förmige, Führungselemente unmittelbar vor der Spinneinrichtung umfasst. Die im Rahmen des Verfahrens verwendete Führungseinrichtung umfasst sonach wenigstens zwei letzte Führungselemente; wie sich im Weiteren ergibt, sind diese Führungselemente typischerweise auf gleicher Höhe bezüglich der Spinneinrichtung, d. h. in gleichem Abstand zu der Spinneinrichtung, jedoch seitlich versetzt zueinander angeordnet. Aus vorstehenden Ausführungen ergibt sich, dass die wenigstens zwei Fasern der Spinneinrichtung über die wenigstens zwei separaten, in wenigstens einer Raumrichtung beabstandet voneinander angeordneten Führungselemente zugeführt werden, unmittelbar bevor diese in dem Faserzusammenführungspunkt zusammengeführt werden.Consequently, as part of the method, a guide device is used which comprises at least two separate, cylindrical or cylinder-shaped guide elements arranged at a distance from one another in at least one spatial direction directly in front of the spinning device. The guide device used in the context of the method thus comprises at least two last guide elements; as will become apparent below, these guide elements are typically at the same level with respect to the spinning device, i. H. arranged at the same distance from the spinning device, but laterally offset from one another. It follows from the above statements that the at least two fibers are fed to the spinning device via the at least two separate guide elements arranged spaced apart from one another in at least one spatial direction, immediately before they are brought together at the fiber merging point.

Über eine Zuführung der zu einem Garn zu verspinnenden Fasern über wenigstens zwei separate, in wenigstens einer Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente ist eine Beeinflussung, d. h. insbesondere eine Vergrößerung, der freien Länge der zu einem Garn zu verspinnenden Fasern zwischen dem Verlassen der Führungseinrichtung und einem Faserzusammenführungspunkt, in welchem die Fasern zusammengeführt werden, möglich, welche sich positiv auf die Eigenschaften des herzustellenden bzw. hergestellten Garns auswirkt. Die Vergrößerung der freien Länge der Fasern ergibt sich daraus, dass der Faserzusammenführungspunkt, in welchem die Fasern zusammengeführt werden, wenn die Fasern über separate Führungselemente zugeführt werden, im Vergleich deutlich weiter beabstandet von den letzten Führungselementen und somit deutlich näher an der Spinneinrichtung liegt.By feeding the fibers to be spun into a yarn via at least two separate guide elements arranged at a distance from one another in at least one spatial direction, it is possible to influence, i. H. In particular, an increase in the free length of the fibers to be spun into a yarn between leaving the guide device and a fiber merging point at which the fibers are brought together is possible, which has a positive effect on the properties of the yarn to be produced or produced. The increase in the free length of the fibers results from the fact that the fiber gathering point, at which the fibers are brought together when the fibers are fed via separate guide elements, is in comparison significantly further away from the last guide elements and is therefore significantly closer to the spinning device.

Ein entsprechender Faserzusammenführungspunkt stellt einen Teil eines so genannten Spinndreiecks dar. Der Faserzusammenführungspunkt bildet dabei eine der Spinneinrichtung zugewandte Spitze des Spinndreiecks. Mithin lässt sich auch die Gestalt des Spinndreiecks verfahrensgemäß im Vergleich zu konventionellen Verfahren verändern, da das Spinndreieck aufgrund der erwähnten Vergrößerung der freien Länge der die Seiten des Spinndreiecks bildenden Fasern in Faserführungsrichtung "gestreckt" wird.A corresponding fiber merging point represents part of a so-called spinning triangle. The fiber merging point forms a tip of the spinning triangle facing the spinning device. Consequently, the shape of the spinning triangle can also be changed according to the method compared to conventional processes, since the spinning triangle is "stretched" in the direction of fiber guidance due to the aforementioned increase in the free length of the fibers forming the sides of the spinning triangle.

Dem Verfahren liegt die Erkenntnis zugrunde, dass über eine Beeinflussung, d. h. insbesondere eine Vergrößerung, der freien Länge der zu einem Garn zu verspinnenden Fasern zwischen dem Verlassen der Führungseinrichtung, d. h. dem (faserbezogen) jeweiligen letzten Führungselement, und dem Faserzusammenführungspunkt, in welchem die Fasern zusammengeführt werden, besondere, insbesondere mechanische, Eigenschaften des herzustellenden bzw. hergestellten Garns erhalten werden können. Dies ergibt sich insbesondere dadurch, dass die freie Länge der zu dem Garn zu verspinnenden Fasern vor dem Faserzusammenführungspunkt im Vergleich zu konventionellen Verfahren (deutlich) vergrößert wird. Die (einzelnen) Fasern können sich bereits vor dem Faserzusammenführungspunkt (erheblich) verdrehen ("vertwisten"), was sich positiv auf die Eigenschaften des herzustellenden bzw. hergestellten Garns auswirkt. Anhand von Untersuchungen konnte gezeigt werden, dass derart insbesondere die Bildung so genannter "Neps" (Noppen, Nissen) reduziert werden kann; die verfahrensgemäß hergestellten Garne zeigen demnach eine (deutlich) geringere Neigung zur Bildung von "Neps" sowie eine (deutlich) geringere Haarigkeit. Mit dem Verfahren lassen sich demnach Garne mit verbesserten Eigenschaften herstellen.The method is based on the finding that by influencing, ie in particular increasing, the free length of the fibers to be spun into a yarn between leaving the guide device, ie the (fiber-related) respective last guide element, and the fiber merging point in which the fibers are merged, special, in particular mechanical, properties of the yarn to be produced or produced can be obtained. This results in particular from the fact that the free length of the fibers to be spun to form the yarn is (significantly) increased before the fiber merging point in comparison to conventional methods. The (individual) fibers can (considerably) twist ("twist") before the fiber merging point, which has a positive effect on the properties of the yarn to be produced or produced. Studies have shown that in particular the formation of so-called "neps" (pimples, nits) can be reduced in this way; the yarns produced according to the process accordingly show a (significantly) lower tendency to form "Neps" and (significantly) less hairiness. Accordingly, yarns with improved properties can be produced with the method.

Die freie Länge einer jeweiligen Faser zwischen der Führungseinrichtung und dem Zusammenführungspunkt liegt in einem Bereich zwischen 4 und 20 cm, insbesondere in einem Bereich zwischen 7,5 und 15 cm, bevorzugt bei 10 cm. Insbesondere ab freien Faserlängen von wenigstens 4 cm, insbesondere wenigstens 6 cm, können besonders vorteilhafte Fasereigenschaften erhalten werden.The free length of each fiber between the guide device and the point of convergence is in a range between 4 and 20 cm, in particular in a range between 7.5 and 15 cm, preferably 10 cm. Particularly advantageous fiber properties can be obtained in particular from free fiber lengths of at least 4 cm, in particular at least 6 cm.

Verfahrensgemäß wird insbesondere eine Spinneinrichtung verwendet, deren Spindel- oder Spulenelement mit einem dem durch die räumlich beabstandete Anordnung der diesem zugeordneten Führungselemente zwischen den Führungselementen gebildeten Zwischenraum in Faserführungsrichtung fluchtend angeordnet ist. Das Spindel- oder Spulenelement ist demnach bezüglich der Faserführungsrichtung seitlich versetzt relativ zu den diesem zugeordneten Führungselementen angeordnet; insbesondere ist das Spindel- oder Spulenelement, wenngleich in Faserführungsrichtung von den Führungselementen beabstandet, mittig zwischen den diesem zugeordneten Führungselementen angeordnet. Analoges gilt für das Spinnen mehrerer Garne jeweils aus wenigstens zwei Fasern. In diesem Fall sind die jeweiligen Spindel- bzw. Spulenelemente jeweils mit einem dem durch die räumlich beabstandete Anordnung der diesen jeweils zugeordneten Führungselemente zwischen den diesen jeweils zugeordneten Führungselementen gebildeten Zwischenraum in Faserführungsrichtung fluchtend angeordnet.According to the method, a spinning device is used in particular, the spindle or spool element of which is arranged in alignment with the space formed between the guide elements by the spatially spaced arrangement of the guide elements associated therewith in the fiber guide direction. The spindle or bobbin element is therefore arranged laterally offset relative to the guide elements assigned to it with respect to the fiber guide direction; In particular, the spindle or bobbin element is arranged centrally between the guide elements assigned to it, although it is spaced apart from the guide elements in the fiber guide direction. The same applies to the spinning of several yarns, each consisting of at least two fibers. In this case, the respective spindle or coil elements are each arranged in alignment with a space formed by the spatially spaced arrangement of the guide elements assigned to them between the guide elements assigned to them in the fiber guiding direction.

Wie erwähnt, sind die Führungselemente typischerweise auf gleicher Höhe bezüglich der Spinneinrichtung, jedoch seitlich versetzt zueinander angeordnet. Mithin werden im Rahmen des Verfahrens wenigstens zwei in einer quer zur Faserführungsrichtung verlaufenden Raumrichtung bzw. -ebene räumlich beabstandet voneinander angeordnete Führungselemente verwendet. Es werden jeweils zylinderartige oder -förmige Grundform aufweisende Führungselemente verwendet, welche koaxial und in Richtung deren jeweiliger Zentralachsen räumlich beabstandet voneinander angeordnet sind. Zwei in einer quer zur Faserführungsrichtung verlaufenden Raumrichtung bzw. - ebene räumlich beabstandet voneinander angeordnete Führungselemente können als ein einem bestimmten Spindel- bzw. Spulenelement zugeordnetes Führungselementpaar bezeichnet bzw. erachtet werden, über welches die das auf dem jeweiligen Spindel- bzw. Spulenelement aufzuwickelnde Garn bildenden Fasern zugeführt werden.As mentioned, the guide elements are typically at the same height with respect to the spinning device, but are arranged laterally offset from one another. Consequently, within the framework of the method, at least two guide elements arranged spatially spaced apart from one another in a spatial direction or plane running transversely to the fiber guiding direction are used. In each case, guide elements having a cylindrical or cylindrical basic shape are used, which are arranged coaxially and spatially spaced apart from one another in the direction of their respective central axes. Two guide elements arranged at a distance from one another in a spatial direction or plane running transversely to the fiber guiding direction can be referred to or considered as a pair of guide elements assigned to a specific spindle or bobbin element, via which the yarn to be wound on the respective spindle or bobbin element forms Fibers are fed.

Die freie Länge zwischen jeweiligen Punkten, an welchen die jeweiligen Fasern das jeweilige Führungselement in Richtung des bzw. eines Zusammenführungspunkts verlässt, liegt in einem Bereich zwischen 4 und 10 cm, insbesondere zwischen 5 und 9 cm, bevorzugt wenigstens bei ca. 6 cm.The free length between respective points at which the respective fibers leave the respective guide element in the direction of the or a merging point is in a range between 4 and 10 cm, in particular between 5 and 9 cm, preferably at least about 6 cm.

Wie erwähnt, werden die Fasern in einem Faserzusammenführungspunkt zusammengeführt. Der Faserzusammenführungspunkt bildet, wie ebenso erwähnt, eine der Spinneinrichtung zugewandte Spitze eines Spinndreiecks. Der Winkel des Spinndreiecks im Bereich der der Spinneinrichtung zugewandten Spitze liegt in einem Bereich zwischen 0 und 90° bzw. 1 und 90°; insbesondere beträgt der Winkel weniger als 90°, insbesondere weniger als 45°, insbesondere weniger als 30°. Der Winkel zwischen den wenigstens zwei Fasern nach Verlassen der jeweiligen Führungselemente liegt damit in einem Bereich zwischen 0 und 90° bzw. 1 und 90°, insbesondere beträgt der Winkel weniger als 90° insbesondere weniger als 45°, insbesondere weniger als 30°. Bei dem Winkel handelt es sich demnach typischerweise um einen spitzen Winkel.As mentioned, the fibers are brought together at a fiber gathering point. As also mentioned, the fiber merging point forms a tip of a spinning triangle facing the spinning device. The angle of the spinning triangle in the area of the tip facing the spinning device is in a range between 0 and 90° or 1 and 90°; in particular, the angle is less than 90°, in particular less than 45°, in particular less than 30°. The angle between the at least two fibers after leaving the respective guide elements is therefore in a range between 0 and 90° or 1 and 90°, in particular the angle is less than 90°, in particular less than 45°, in particular less than 30°. The angle is therefore typically an acute angle.

Im Rahmen des Verfahrens ist es auch möglich, dass wenigstens drei Fasern zur Ausbildung des Garns miteinander versponnen werden. Die wenigstens drei Fasern werden typischerweise in dem Faserzusammenführungspunkt zusammengeführt. Mithin können Garne aus mehr als zwei Fasern (Multifasergarne) hergestellt werden.As part of the process, it is also possible for at least three fibers to be spun together to form the yarn. The at least three fibers are typically brought together at the fiber gathering point. Consequently, yarns can be produced from more than two fibers (multi-fiber yarns).

Das verfahrensgemäße Verspinnen von wenigstens drei Fasern zur Ausbildung eines Garns kann derart realisiert werden, dass wenigstens zwei Fasern der Spinneinrichtung gemeinsam über ein erstes Führungselement und wenigstens eine weitere Faser über ein zu dem ersten Führungselement in wenigstens einer Raumrichtung bzw. -ebene räumlich beabstandet angeordnetes weiteres Führungselement zugeführt wird. Wenigstens zwei Fasern können sonach über ein erstes Führungselement zugeführt werden und wenigstens eine weitere Faser über ein weiteres Führungselement zugeführt werden. In diesem Zusammenhang sind gleich- oder ungleichmäßige Aufteilungen von Fasern über eine gegebene Anzahl an Führungselementen möglich, sodass bei einer beispielhaften Zuführung von vier Fasern und einer beispielhaften Anzahl an zwei Führungselementen zwei Fasern über ein erstes Führungselement und zwei Fasern über ein zweites Führungselement zugeführt werden oder drei Fasern über ein erstes Führungselement zugeführt werden und eine Faser über ein zweites Führungselement zugeführt wird.The spinning of at least three fibers according to the method to form a yarn can be implemented in such a way that at least two fibers of the spinning device are guided together via a first guide element and at least one additional fiber via a further guide element that is spatially spaced apart from the first guide element in at least one spatial direction or plane Guide element is supplied. At least two fibers can thus be fed via a first guide element and at least one further fiber can be fed via a further guide element. In this context, even or uneven distributions of fibers over a given number of guide elements are possible, so that with an exemplary feed of four fibers and an exemplary number of two guide elements, two fibers are fed via a first guide element and two fibers via a second guide element or three fibers are fed via a first guide element and one fiber is fed via a second guide element.

Alternativ kann das verfahrensgemäße Verspinnen von wenigstens drei Fasern zur Ausbildung eines Garns derart realisiert werden, dass die wenigstens drei Fasern der Spinneinrichtung über drei separate, in wenigstens einer Raumrichtung bzw. -ebene beabstandet voneinander angeordnete Führungselemente zugeführt werden, wobei wenigstens eine erste Faser über ein erstes Führungselement zugeführt wird, wenigstens eine zweite Faser über ein zu dem ersten Führungselement in wenigstens einer Raumrichtung bzw. -ebene räumlich beabstandet angeordnetes zweites Führungselement zugeführt wird und wenigstens eine dritte Faser über ein zu dem zweiten Führungselement in wenigstens einer Raumrichtung bzw. -ebene räumlich beabstandet angeordnetes drittes Führungselement zugeführt wird. Jede Faser kann sonach auch über ein separates Führungselement zugeführt werden.Alternatively, the spinning of at least three fibers according to the method to form a yarn can be implemented in such a way that the at least three fibers are fed to the spinning device via three separate guide elements arranged at a distance from one another in at least one spatial direction or plane, with at least one first fiber being guided via a first guide element is fed, at least one second fiber is fed via a second guide element arranged spatially spaced from the first guide element in at least one spatial direction or plane, and at least one third fiber via a spatially spaced from the second guide element in at least one spatial direction or plane spaced-apart third guide element is supplied. Each fiber can therefore also be fed via a separate guide element.

Im Rahmen des Verfahrens ist es auch möglich, dass wenigstens zwei Fasern und wenigstens ein Filament - hierbei kann es sich um ein Einzel- oder Multi-Filament handeln - zur Ausbildung des Garns miteinander versponnen werden. Die wenigstens zwei Fasern und das wenigstens eine Filament werden typischerweise in dem Faserzusammenführungspunkt zusammengeführt. Mithin können Garne aus wenigstens zwei Fasern und wenigstens einem Filament hergestellt werden. Ein entsprechendes Filament kann ein Endlos-Filament sein. Ein entsprechendes Filament kann aus einem elastischen Filamentmaterial gebildet sein bzw. ein solches umfassen; bei einem Filament kann es sich z. B. um ein Filament aus Elasthan (bisweilen im Handel als Lycra bezeichnet), Polyamid, Polyester oder Polypropylen handeln.Within the scope of the method, it is also possible for at least two fibers and at least one filament—this can be a single or multi-filament—to be spun together to form the yarn. The at least two fibers and the at least one filament are typically brought together at the fiber gathering point. Consequently, yarns can be produced from at least two fibers and at least one filament. A corresponding filament can be an endless filament. A corresponding filament can be formed from or comprise an elastic filament material; a filament can be e.g. B. be a filament of elastane (sometimes referred to commercially as Lycra), polyamide, polyester or polypropylene.

Das verfahrensgemäße Verspinnen von wenigstens zwei Fasern und wenigstens einem Filament kann derart realisiert werden, dass wenigstens zwei Fasern der Spinneinrichtung über zwei separate, in wenigstens einer Raumrichtung bzw. -ebene beabstandet voneinander angeordnete, Führungselemente zugeführt werden und das wenigstens eine Filament aus einem (gesonderten), insbesondere spulenartigen bzw. -förmigen, Filamentenspeicher, wie z. B. einer Filamentenspule, oder über ein zu den zwei separaten Führungselementen separates drittes Führungselement zugeführt wird.The spinning of at least two fibers and at least one filament according to the method can be implemented in such a way that at least two fibers are fed to the spinning device via two separate guide elements arranged at a distance from one another in at least one spatial direction or plane and the at least one filament consists of a (separate ), In particular coil-like or -shaped, filament storage, such. B. a filament coil, or via a separate to the two separate guide elements third guide element.

Selbstverständlich ist es möglich, dass die wenigstens zwei Fasern der Spinneinrichtung mit einer durch eine Streckung, insbesondere Längsstreckung, der Fasern erzeugten Vorspannung zugeführt werden. Analoges gilt für zugeführte Filamente. Insbesondere ist dabei eine Implementierung unterschiedlicher Streckbereiche bzw. -zonen, d. h. z. B. einer Vorstreckzone und einer Hauptstreckzone, möglich, in welchen die Fasern bzw. Filamente unterschiedlich stark gestreckt werden.Of course, it is possible for the at least two fibers to be fed to the spinning device with a prestress produced by stretching, in particular longitudinal stretching, of the fibers. The same applies to supplied filaments. In particular, an implementation of different stretching areas or zones, i. H. e.g. B. a pre-stretching zone and a main stretching zone, in which the fibers or filaments are stretched to different degrees.

Im Rahmen des Verfahrens können Fasern gleicher und ungleicher chemischer und/oder geometrischer und/oder physikalischer, insbesondere mechanischer, Eigenschaften zur Ausbildung des Garns miteinander versponnen werden. Die verfahrensgemäß versponnenen Fasern können, sofern diese nicht gleich sind, sich also in wenigstens einer chemischen Eigenschaft, d. h. insbesondere in wenigstens einer die chemischen Eigenschaften der Faser betreffenden Eigenschaft, wie z. B. der chemischen Zusammensetzung, und/oder in wenigstens einer geometrischen Eigenschaft, d. h. insbesondere in wenigstens einer die Geometrie der Faser betreffenden Eigenschaft, wie z. B. Faserdurchmesser, und/oder in wenigstens einer physikalischen, insbesondere mechanischen, Eigenschaft, d. h. insbesondere in wenigstens einer die physikalischen insbesondere mechanischen Eigenschaften der Faser betreffenden Eigenschaft, wie z. B. Faserfestigkeit, unterscheiden.As part of the process, fibers of the same and different chemical and/or geometric and/or physical, in particular mechanical, properties can be spun together to form the yarn. The fibers spun according to the process can, if they are not the same, differ in at least one chemical property, i. H. in particular in at least one property relating to the chemical properties of the fibre, such as e.g. B. the chemical composition, and / or in at least one geometric property, d. H. in particular in at least one property relating to the geometry of the fiber, such as e.g. B. fiber diameter, and / or in at least one physical, in particular mechanical, property, d. H. in particular in at least one property relating to the physical, in particular mechanical, properties of the fiber, such as e.g. B. fiber strength distinguish.

An dieser Stelle ist allgemein zu erwähnen, dass im Rahmen des Verfahrens grundsätzlich sämtliche natürliche Fasern, d. h. z. B. Alpakafasern, Baumwollfasern, Kaschmirfasern, Mohairfasern, Seidefasern, Leinenfasern, Wollfasern, insbesondere Schurwollfasern, und/oder künstliche (synthetische) Fasern, d. h. z. B. Kunststoffasern, insbesondere Polyamidfasern, Polyesterfasern, Polypropylenfasern, Viskosefasern, zur Ausbildung des herzustellenden Garns miteinander versponnen werden können. Insbesondere sind auch Mischungen natürlicher und künstlicher Fasern denkbar. Bei den Fasern kann es sich, je nach Verfügbarkeit, um Endlos- oder Stapelfasern handeln.At this point it should be mentioned in general that in the course of the process all natural fibres, ie e.g. alpaca fibres, cotton fibres, cashmere fibres, mohair fibres, silk fibres, linen fibres, wool fibres, in particular new wool fibres, and/or artificial (synthetic) fibres, ie e.g. Plastic fibers, in particular polyamide fibers, polyester fibers, polypropylene fibers, viscose fibers, can be spun together to form the yarn to be produced. In particular, mixtures are more natural and artificial fibers conceivable. The fibers can be continuous or staple, depending on availability.

Auch eine (einzelne) Faser kann aus wenigstens zwei chemisch und/oder geometrisch und/oder physikalisch unterschiedlichen Fasermaterialien gebildet sein bzw. wenigstens zwei chemisch und/oder geometrisch und/oder physikalisch unterschiedliche Fasermaterialien umfassen. Eine entsprechende demnach auch als Mischfaser (Mischroving) zu bezeichnende Faser kann demnach z. B. aus einem ersten Fasermaterial (Rovingmaterial) und wenigstens einem weiteren Fasermaterial (Rovingmaterial) gebildet sein. Bei einem ersten Fasermaterial kann es sich z. B. um ein natürliches Fasermaterial, wie z. B. Wolle, bei einem weiteren Fasermaterial kann es sich z. B. um ein künstliches (synthetisches) Fasermaterial, wie z. B. Polyamid, Polyester, Polypropylen, handeln. Bei den Fasern kann es sich, wie erwähnt, je nach Verfügbarkeit, um Endlos- oder Stapelfasern handeln.A (single) fiber can also be formed from at least two chemically and/or geometrically and/or physically different fiber materials or comprise at least two chemically and/or geometrically and/or physically different fiber materials. A corresponding fiber, which can also be designated as a mixed fiber (mixed roving), can therefore be used e.g. B. from a first fiber material (roving material) and at least one other fiber material (roving material) may be formed. A first fiber material can be z. B. a natural fiber material such. B. wool, with another fiber material, it can be z. B. an artificial (synthetic) fiber material such. As polyamide, polyester, polypropylene act. As mentioned, the fibers can be continuous or staple fibers, depending on availability.

Fig. 1 zeigt eine Prinzipdarstellung einer Vorrichtung 1 zur Herstellung eines durch Verspinnen wenigstens zweier einzelner Fasern 2a, 2b ausgebildeten Garns 3 gemäß einem Ausführungsbeispiel. Fig. 1 stellt eine schematische Aufsicht auf die Vorrichtung 1 dar. Fig. 3 zeigt eine vergrößerte Darstellung der in Fig. 1 gezeigten Einzelheit III. 1 shows a schematic representation of a device 1 for producing a yarn 3 formed by spinning at least two individual fibers 2a, 2b according to an exemplary embodiment. 1 represents a schematic plan view of the device 1. 3 shows an enlarged view of the in 1 shown detail III.

Die z. B. als Ringspinnmaschine ausgebildete oder eine solche umfassende Vorrichtung 1 umfasst folgende Bestandteile: wenigstens zwei Faservorräte 4a, 4b, eine diesen in der durch den Pfeil P angedeuteten Faserführungsrichtung nachgeschaltet angeordnete Führungseinrichtung 5 und eine der Führungseinrichtung 5 in Faserführungsrichtung nachgeschaltet angeordnete Spinneinrichtung 6. Das funktionelle Zusammenwirken der genannten Bestandteile der Vorrichtung 1 wird im Folgenden näher beschrieben:
Über die Faservorräte 4a, 4b, bei welchen es sich z. B. um Faserspulen, von welchen die im Rahmen des Verfahrens zu einem Garn 3 zu verspinnenden Fasern 2a, 2b abgewickelt werden, handeln kann, werden die zur Ausbildung des herzustellenden Garns 3 miteinander zu verspinnenden einzelnen Fasern 2a, 2b bereitgestellt. Die Fasern 2a, 2b können auch als Roving bzw. Vorgarn bezeichnet bzw. erachtet werden. In dem Ausführungsbeispiel sind rein exemplarisch nur zwei Faservorräte 4a, 4b gezeigt; das im Folgenden beschriebene Prinzip lässt sich jedoch beliebig auf mehr als zwei Faservorräte 4a, 4b und somit mehr als zwei Fasern 2a, 2b erweitern. Die Anzahl der Faservorräte 4a, 4b bestimmt sich nach der Anzahl der verfahrensgemäß zu einem Garn 3 zu verspinnenden Fasern 2a, 2b.
the z. The device 1, e.g. designed as a ring spinning machine or comprising such a device, comprises the following components: at least two fiber stores 4a, 4b, a guide device 5 arranged downstream of these in the fiber guide direction indicated by the arrow P, and a spinning device 6 arranged downstream of the guide device 5 in the fiber guide direction The interaction of the named components of the device 1 is described in more detail below:
About the fiber stocks 4a, 4b, which are z. The individual fibers 2a, 2b to be spun together to form the yarn 3 to be produced are provided, e.g. The fibers 2a, 2b can also be referred to or considered as roving or roving. In the exemplary embodiment, only two fiber supplies 4a, 4b are shown purely by way of example; however, the principle described below can be extended to more than two fiber supplies 4a, 4b and thus more than two fibers 2a, 2b. The number of fiber supplies 4a, 4b is determined by the number of fibers 2a, 2b to be spun into a yarn 3 according to the method.

Die Führungseinrichtung 5 ist eingerichtet, die bereitgestellten Fasern 2a, 2b zu der in Faserführungsrichtung nachgeschaltet angeordneten Spinneinrichtung 6 zu führen. Die Führungseinrichtung 5 umfasst hierzu eine Mehrzahl an - in den in Fig. gezeigten Ausführungsbeispielen jeweils beispielhaft fünf - in Faserführungsrichtung hintereinander geschaltet angeordneten Führungselementen 5a - 5e, sodass die zu führenden Fasern 2a, 2b von einem ersten Führungselement 5a auf die diesem in Faserführungsrichtung nachgeschaltet angeordneten weiteren Führungselemente 5b - 5e geführt werden können. Das in Faserführungsrichtung erste Führungselement 5a ist den jeweiligen Faservorräten 4a, 4b in Faserführungsrichtung unmittelbar nachgeschaltet angeordnet, die in Faserführungsrichtung letzten Führungselemente 5d, 5e sind der Spinneinrichtung 6 in Faserführungsrichtung unmittelbar vorgeschaltet angeordnet. Zwischen in Faserführungsrichtung (unmittelbar) aufeinanderfolgend, gleichwohl in Faserführungsrichtung beabstandet angeordneten Führungselementen 5a - 5e können geeignete, z. B. plattenartige bzw. -förmige, Stützelemente 7 vorgesehen werden, welche eine gewünschte Stützwirkung auf die zu führenden Fasern 2a, 2b ausüben. In den in den Fig. gezeigten Ausführungsbeispielen ist ein entsprechendes Stützelement 7 beispielhaft zwischen dem ersten Führungselement 5a und den Faservorräten 4a, 4b angeordnet.The guide device 5 is set up to guide the provided fibers 2a, 2b to the spinning device 6 arranged downstream in the fiber guide direction. For this purpose, the guide device 5 comprises a plurality of guide elements 5a - 5e - in the exemplary embodiments shown in Fig. five in each case - arranged one behind the other in the fiber guide direction, so that the fibers 2a, 2b to be guided are arranged from a first guide element 5a to those arranged downstream of this in the fiber guide direction further guide elements 5b - 5e can be performed. The first guide element 5a in the fiber guide direction is arranged immediately downstream of the respective fiber stores 4a, 4b in the fiber guide direction, the last guide elements 5d, 5e in the fiber guide direction are arranged immediately upstream of the spinning device 6 in the fiber guide direction. Between guide elements 5a - 5e which are arranged (directly) one after the other in the fiber guide direction but spaced apart in the fiber guide direction, suitable, e.g. B. plate-like or -shaped, supporting elements 7 can be provided, which exert a desired supporting effect on the fibers 2a, 2b to be guided. In the exemplary embodiments shown in the figures, a corresponding support element 7 is arranged, for example, between the first guide element 5a and the fiber supplies 4a, 4b.

Die Führungselemente 5a - 5e weisen jeweils eine zylinderartige bzw. -förmige geometrische Gestalt bzw. Grundform auf; die Führungselemente 5a - 5e können sonach als Führungsrollen bzw. -walzen bzw. -zylinder bezeichnet bzw. erachtet werden. Die Führungselemente 5a - 5e sind jeweils um ihre Symmetrie- bzw. Zentralachse drehbar gelagert, sodass sich durch Drehbewegungen der Führungselemente 5a - 5e um ihre jeweilige Symmetrie- bzw. Zentralachse eine geführte Bewegung der zu führenden Fasern 2a, 2b in Richtung der Spinneinrichtung 6 ermöglichen lässt.The guide elements 5a - 5e each have a cylindrical or -shaped geometric shape or basic shape; the guide elements 5a - 5e can therefore be referred to or considered as guide rollers or rollers or cylinders. The guide elements 5a - 5e are each rotatably mounted about their symmetry or central axis, so that a guided movement of the fibers 2a, 2b to be guided in the direction of the spinning device 6 is made possible by rotary movements of the guide elements 5a - 5e about their respective symmetry or central axis leaves.

Einzelne, mehrere oder sämtliche Führungselemente 5a - 5e können mit einer bestimmten, z. B. durch eine Gummierung realisierten, Haft(ober)fläche (nicht gezeigt) versehen sein, welche aufgrund einer auf die Fasern 2a, 2b ausgeübten Haftwirkung eine gewünschte Führung der Fasern 2a, 2b ermöglicht, d. h. insbesondere ein bezüglich der Faserführungsrichtung unerwünschtes seitliches Verrutschen der Fasern 2a, 2b erschwert bzw. verhindert.Individual, several or all guide elements 5a - 5e can be provided with a specific, e.g. B. realized by a rubber coating, adhesive (surface) (not shown) can be provided, which due to an adhesive effect exerted on the fibers 2a, 2b allows a desired guidance of the fibers 2a, 2b, d. H. in particular, a lateral slippage of the fibers 2a, 2b, which is undesirable with respect to the direction of fiber guidance, is made more difficult or prevented.

In dem in den Fig 1, 3 gezeigten Ausführungsbeispiel - Analoges gilt für das in den Fig. 2, 4 gezeigte Ausführungsbeispiel - sind ferner (optionale) Streckelemente ("Condenser") 8a, 8b, 9a, 9b einer nicht näher bezeichneten Streckeinrichtung dargestellt. Mithin können die Fasern 2a, 2b der Spinneinrichtung 6 mit einer durch eine Streckung, insbesondere Längsstreckung, der Fasern 2a, 2b erzeugten Vorspannung zugeführt werden. Dabei ist durch unterschiedliche Streckelemente 8a, 8b, 9a, 9b eine Implementierung unterschiedlicher Streckbereiche bzw. - zonen, d. h. z. B. einer Vorstreckzone und einer Hauptstreckzone, möglich, in welchen die Fasern 2a, 2b unterschiedlich stark gestreckt werden. Bei den Streckelementen 8a, 8b, 9a, 9b kann es sich um speziell für das hierin beschriebene Verfahren konstruktiv modifizierte Streckelemente handeln, welche eine für das hierin beschriebene Verfahren erforderliche Führung bzw. Streckung der Fasern 2a, 2b ermöglichen.In the in the figure 1 , 3 shown embodiment - the same applies to in the 2 , 4 shown embodiment - are also shown (optional) stretching elements ("condenser") 8a, 8b, 9a, 9b of a stretching device not specified. Consequently, the fibers 2a, 2b can be fed to the spinning device 6 with a prestress produced by stretching, in particular longitudinal stretching, of the fibers 2a, 2b. Different stretching elements 8a, 8b, 9a, 9b make it possible to implement different stretching areas or zones, ie, for example, a pre-stretching zone and a main stretching zone, in which the fibers 2a, 2b are stretched to different extents. The stretching elements 8a, 8b, 9a, 9b can be stretching elements that have been specially modified in terms of their design for the method described here and which enable the fibers 2a, 2b to be guided or stretched as required for the method described here.

Die Spinneinrichtung 6 ist eingerichtet, die dieser über die Führungseinrichtung 5 zugeführten Fasern 2a, 2b unter Ausbildung eines Garns 3 miteinander zu verspinnen. Die Spinneinrichtung 6 umfasst hierfür ein um eine Spindel- oder Spulenachse (nicht gezeigt) drehbar gelagertes Spindel- oder Spulenelement 10, auf welches das Garn 3 aufwickelbar ist. Dem Spindel- oder Spulenelement 10 ist in den in den Fig. gezeigten Ausführungsbeispielen ein Fadenführer bzw. -wächter16 vorgeschaltet.The spinning device 6 is set up to spin the fibers 2 a , 2 b supplied via the guide device 5 with one another, forming a yarn 3 . For this purpose, the spinning device 6 comprises a spindle or bobbin element 10 which is rotatably mounted about a spindle or bobbin axis (not shown) and onto which the yarn 3 can be wound. In the exemplary embodiments shown in the figures, a thread guide or thread monitor 16 is connected upstream of the spindle or spool element 10 .

Wie anhand der Fig. ersichtlich ist, zeichnet sich die Vorrichtung 1 dadurch aus, dass die Führungseinrichtung 5 wenigstens zwei separate, in wenigstens einer Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente 5d, 5e umfasst, über welche die Fasern 2a, 2b der Spinneinrichtung 6 zuführbar oder zugeführt sind. Ersichtlich handelt es sich bei den Führungselemente 5d, 5e um die in Faserführungsrichtung letzten Führungselemente 5d, 5e vor der Spinneinrichtung 6. Die Führungselemente 5d, 5e sind auf gleicher Höhe bezüglich der Spinneinrichtung 6, jedoch seitlich versetzt zueinander angeordnet (vgl. insbesondere Fig. 3).As can be seen from the figure, the device 1 is characterized in that the guide device 5 comprises at least two separate guide elements 5d, 5e which are spaced apart from one another in at least one spatial direction and via which the fibers 2a, 2b can be fed to the spinning device 6 or are supplied. As can be seen, the guide elements 5d, 5e are the last guide elements 5d, 5e in the fiber guiding direction in front of the spinning device 6. The guide elements 5d, 5e are arranged at the same height in relation to the spinning device 6, but laterally offset from one another (cf. in particular 3 ).

Mit der in den Fig. gezeigten Vorrichtung 1 lässt sich ein Verfahren zur Herstellung eines durch Verspinnen zweier Fasern 2a, 2b ausgebildeten Garns 3 mit verbesserten Garneigenschaften implementieren. Ein Ausführungsbeispiel eines solchen Verfahrens wird im Folgenden näher beschrieben.With the device 1 shown in the figure, a method for producing a yarn 3 formed by spinning two fibers 2a, 2b with improved yarn properties can be used to implement. An exemplary embodiment of such a method is described in more detail below.

In einem ersten Schritt des Verfahrens erfolgt das Bereitstellen der zur Ausbildung des herzustellenden Garns 3 miteinander zu verspinnenden einzelnen Fasern 2a, 2b über die Faservorräte 4a, 4b.In a first step of the method, the individual fibers 2a, 2b to be spun together to form the yarn 3 to be produced are provided via the fiber stocks 4a, 4b.

In einem zweiten Schritt des Verfahrens erfolgt ein Zuführen der bereitgestellten Fasern 2a, 2b zu der Spinneinrichtung 6 über die Führungseinrichtung 5.In a second step of the method, the fibers 2a, 2b provided are fed to the spinning device 6 via the guide device 5.

In einem dritten Schritt des Verfahrens erfolgt ein Verspinnen der der Spinneinrichtung 6 zugeführten Fasern 2a, 2b in der Spinneinrichtung 6 unter Ausbildung des herzustellenden Garns 3. Das Verspinnen der Fasern 2a, 2b erfolgt in einem sich an die letzten Führungselemente 5d, 5e anschließenden Spinnbereich 11. Das hergestellte Garn 3 wird auf das Spindel- oder Spulenelement 10 aufgewickelt.In a third step of the method, the fibers 2a, 2b fed to the spinning device 6 are spun in the spinning device 6 to form the yarn 3 to be produced. The fibers 2a, 2b are spun in a spinning area 11 adjoining the last guide elements 5d, 5e The yarn 3 produced is wound onto the spindle or bobbin member 10 .

Anhand der Fig. ist ersichtlich, dass verfahrensgemäß die zu einem Garn 3 zu verspinnenden Fasern 2a, 2b der Spinneinrichtung 6 über zwei separate, in einer Raumrichtung räumlich beabstandet voneinander angeordnete, Führungselemente 5d, 5e zugeführt werden. Die Fig. zeigen, dass eine erste zur Ausbildung des Garns 3 zu verspinnende Faser 2a der Spinneinrichtung 6 über ein erstes Führungselement 5d zugeführt wird und eine mit der ersten Faser 2b zur Ausbildung des Garns 3 zu verspinnende zweite Faser 2b der Spinneinrichtung 6 über ein zu dem ersten Führungselement 5d beabstandet angeordnetes zweites Führungselement 5e zugeführt wird.It can be seen from the figure that, according to the method, the fibers 2a, 2b to be spun into a yarn 3 are fed to the spinning device 6 via two separate guide elements 5d, 5e that are spaced apart from one another in one spatial direction. The figures show that a first fiber 2a to be spun to form the yarn 3 is fed to the spinning device 6 via a first guide element 5d and a second fiber 2b to be spun with the first fiber 2b to form the yarn 3 is fed to the spinning device 6 via a second guide element 5e arranged spaced apart from the first guide element 5d.

Im Rahmen des Verfahrens wird demnach eine Führungseinrichtung 5 verwendet, welche wenigstens zwei separate, in einer Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente 5d, 5e unmittelbar vor der Spinneinrichtung 6 umfasst. Die Führungselemente 5d, 5e sind, wie erwähnt, auf gleicher Höhe bezüglich der Spinneinrichtung 6, d. h. in gleichem Abstand zu der Spinneinrichtung 6, jedoch seitlich versetzt zueinander angeordnet. Da die Führungselemente 5d, 5e, wie erwähnt, eine zylinderartige bzw. -förmige geometrische Gestalt bzw. Grundform aufweisen, sind diese in den in den Fig. gezeigten Ausführungsbeispielen koaxial und in Richtung deren jeweiliger Zentralachsen räumlich beabstandet voneinander angeordnet und damit quer zur Faserführungsrichtung verlaufenden Raumrichtung in paralleler Anordnung beabstandet voneinander angeordnet. Zwei in einer quer zur Faserführungsrichtung verlaufenden Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente 5d, 5e können als ein einem bestimmten Spindel- bzw. Spulenelement 10 zugeordnetes Führungselementpaar bezeichnet bzw. erachtet werden, über welches die das auf dem jeweiligen Spindel- bzw. Spulenelement 10 aufzuwickelnde Garn 3 bildenden Fasern 2a, 2b zugeführt werden.Within the framework of the method, a guide device 5 is therefore used which comprises at least two separate guide elements 5d, 5e which are arranged spatially spaced apart from one another directly in front of the spinning device 6. As mentioned, the guide elements 5d, 5e are arranged at the same height in relation to the spinning device 6, ie at the same distance from the spinning device 6, but laterally offset from one another. Since the guide elements 5d, 5e, as mentioned, have a cylindrical or -shaped geometric shape or basic shape, they are arranged coaxially and spatially spaced from each other in the direction of their respective central axes in the exemplary embodiments shown in the figures and thus run transversely to the fiber guide direction Spatial direction in a parallel arrangement spaced apart. Two guide elements 5d, 5e arranged spatially spaced apart from one another in a spatial direction running transversely to the fiber guiding direction can be used as a specific spindle or Coil element 10 associated pair of guide elements are designated or considered, via which the fibers 2a, 2b forming the yarn 3 to be wound on the respective spindle or coil element 10 are fed.

Über die Zuführung der zu einem Garn 3 zu verspinnenden Fasern 2a, 2b über separate, in einer Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente 5d, 5e ist eine Beeinflussung, d. h. insbesondere eine Vergrößerung, der freien Länge L der zu verspinnenden Fasern 2a, 2b zwischen dem Verlassen der Führungseinrichtung 5 und einem Faserzusammenführungspunkt 12, in welchem die Fasern 2a, 2b zusammengeführt werden, möglich, welche sich positiv auf die Eigenschaften des herzustellenden bzw. hergestellten Garns 3 auswirkt. Die Vergrößerung der freien Länge L der Fasern 2a, 2b ergibt sich daraus, dass der Faserzusammenführungspunkt 12 im Vergleich zu konventionellen Verfahren deutlich weiter beabstandet von den letzten Führungselementen 5d, 5e und somit deutlich näher an der Spinneinrichtung 6 liegt.By feeding the fibers 2a, 2b to be spun into a yarn 3 via separate guide elements 5d, 5e arranged spatially spaced apart from one another, an influencing, i. H. In particular, an increase in the free length L of the fibers 2a, 2b to be spun between leaving the guide device 5 and a fiber merging point 12, in which the fibers 2a, 2b are brought together, is possible, which has a positive effect on the properties of the yarn to be produced or produced 3 affects. The increase in the free length L of the fibers 2a, 2b results from the fact that the fiber merging point 12 is significantly further away from the last guide elements 5d, 5e and thus significantly closer to the spinning device 6 compared to conventional methods.

Der Faserzusammenführungspunkt 12 stellt einen Teil eines so genannten Spinndreiecks dar. Der Faserzusammenführungspunkt 12 bildet dabei eine der Spinneinrichtung 6 zugewandte Spitze des Spinndreiecks. Mithin lässt sich auch die Gestalt des Spinndreiecks verfahrensgemäß im Vergleich zu konventionellen Verfahren verändern, da das Spinndreieck aufgrund der erwähnten Vergrößerung der freien Länge L der die Seiten des Spinndreiecks bildenden Fasern 2a, 2b in Faserführungsrichtung "gestreckt" wird.The fiber merging point 12 represents part of a so-called spinning triangle. The fiber merging point 12 forms a tip of the spinning triangle facing the spinning device 6 . The shape of the spinning triangle can therefore also be changed according to the method compared to conventional processes, since the spinning triangle is "stretched" in the direction of fiber guidance due to the aforementioned increase in the free length L of the fibers 2a, 2b forming the sides of the spinning triangle.

Der Winkel α des Spinndreiecks im Bereich der der Spinneinrichtung 6 zugewandten Spitze beträgt weniger als 90°, insbesondere weniger als 45°, insbesondere weniger als 30°. Entsprechend beträgt der Winkel α zwischen den Fasern 2a, 2b nach Verlassen der Führungselemente 5d, 5e weniger als 90° insbesondere weniger als 45°, insbesondere weniger als 30°. Bei dem Winkel α handelt es sich demnach um einen spitzen Winkel.The angle α of the spinning triangle in the area of the tip facing the spinning device 6 is less than 90°, in particular less than 45°, in particular less than 30°. Accordingly, the angle α between the fibers 2a, 2b after leaving the guide elements 5d, 5e is less than 90°, in particular less than 45°, in particular less than 30°. The angle α is therefore an acute angle.

Dem Verfahren liegt die Erkenntnis zugrunde, dass über eine Beeinflussung, d. h. insbesondere eine Vergrößerung, der freien Länge L der zu verspinnenden Fasern 2a, 2b zwischen dem Verlassen der Führungseinrichtung 5, d. h. den letzten Führungselementen 5d, 5e, und dem Faserzusammenführungspunkt 12 besondere, insbesondere mechanische, Eigenschaften des herzustellenden bzw. hergestellten Garns 3 erhalten werden können. Dies ergibt sich insbesondere dadurch, dass die freie Länge L der zu verspinnenden Fasern 2a, 2b vor dem Faserzusammenführungspunkt 12 im Vergleich zu konventionellen Verfahren (deutlich) vergrößert wird. Die (einzelnen) Fasern 2a, 2b können sich bereits vor dem Faserzusammenführungspunkt 12 (erheblich) verdrehen ("vertwisten"), was sich positiv auf die Eigenschaften des herzustellenden bzw. hergestellten Garns 3 auswirkt.The method is based on the finding that by influencing, ie in particular increasing, the free length L of the fibers 2a, 2b to be spun between leaving the guide device 5, ie the last guide elements 5d, 5e, and the fiber merging point 12, special, in particular mechanical, properties of the yarn to be produced or produced 3 can be obtained. This results in particular from the fact that the free length L of the fibers 2a, 2b to be spun before the fiber merging point 12 is (significantly) increased in comparison to conventional methods. The (individual) fibers 2a, 2b can already before Fiber merging point 12 (considerably) twist ("twist"), which has a positive effect on the properties of the yarn 3 to be produced or produced.

Die freie Länge L einer jeweiligen Faser 2a, 2b zwischen der Führungseinrichtung 5 und dem Zusammenführungspunkt 12, in welchem die Fasern 2a, 2b zusammengeführt werden, liegt in einem Bereich zwischen 4 und 20 cm, insbesondere in einem Bereich zwischen 7,5 und 15 cm, bevorzugt bei 10 cm.The free length L of a respective fiber 2a, 2b between the guide device 5 and the meeting point 12 at which the fibers 2a, 2b are brought together is in a range between 4 and 20 cm, in particular in a range between 7.5 and 15 cm , preferably at 10 cm.

Die freie Länge L' zwischen jeweiligen Punkten 14, 15, an welchen die Fasern 2a 2b das jeweilige Führungselement 5d, 5e in Richtung des Zusammenführungspunkts 12 verlassen, liegt in einem Bereich zwischen 4 und 10 cm, insbesondere zwischen 5 und 9 cm, bevorzugt wenigstens bei ca. 6 cm.The free length L' between respective points 14, 15 at which the fibers 2a 2b leave the respective guide element 5d, 5e in the direction of the meeting point 12 is in a range between 4 and 10 cm, in particular between 5 and 9 cm, preferably at least at about 6 cm.

Anhand der Fig. ist ersichtlich, dass verfahrensgemäß eine Spinneinrichtung 6 verwendet wird, deren Spindel- oder Spulenelement 10 mit einem dem durch die räumlich beabstandete Anordnung der diesem zugeordneten Führungselemente 5d, 5e zwischen den Führungselementen 5d, 5e gebildeten Zwischenraum 13 in Faserführungsrichtung fluchtend angeordnet ist. Das Spindel- oder Spulenelement 10 ist demnach (bezüglich der Faserführungsrichtung) seitlich versetzt relativ zu den diesem zugeordneten Führungselementen 5d, 5e angeordnet; insbesondere ist das Spindel- oder Spulenelement 10, wenngleich in Faserführungsrichtung von den Führungselementen 5d, 5e beabstandet, mittig zwischen den diesem zugeordneten Führungselementen 5d, 5e angeordnet.It can be seen from the figure that a spinning device 6 is used according to the method, the spindle or spool element 10 of which is arranged in alignment with an intermediate space 13 formed by the spatially spaced arrangement of the guide elements 5d, 5e assigned to it between the guide elements 5d, 5e in the fiber guide direction . The spindle or bobbin element 10 is accordingly (with respect to the direction of fiber guidance) offset laterally relative to the guide elements 5d, 5e associated therewith; In particular, the spindle or bobbin element 10 is arranged centrally between the guide elements 5d, 5e assigned to it, although it is spaced apart from the guide elements 5d, 5e in the fiber guide direction.

In Fig 3 ist schließlich durch strichlierte Fasern angedeutet, dass über ein jeweiliges letztes Führungselement 5d, 5e prinzipiell auch weitere Fasern (strichliert) geführt werden können, welche jedoch einem anderem Spindel- oder Spulenelement (nicht gezeigt), d. h. typischerweise einem parallel zu dem Spindel- oder Spulenelement 10 angeordneten weiteren Spindel- oder Spulenelement, d. h. einem anderen Spinnbereich, der Spinneinrichtung 6 zugeführt werden. Auch für diesen anderen Spinnbereich gilt, dass die dort zu einem Garn 3 zu verspinnenden Fasern in zu den Fig. gleicher Weise über separate Führungselemente zugeführt werden.In figure 3 Finally, dashed fibers indicate that in principle further fibers (dashed) can also be guided via a respective last guide element 5d, 5e, which, however, belong to another spindle or coil element (not shown), i.e. typically one parallel to the spindle or coil element 10 arranged further spindle or coil element, ie another spinning area, the spinning device 6 are supplied. It is also true for this other spinning area that the fibers to be spun into a yarn 3 there are fed in the same way as in the figures via separate guide elements.

Fig. 2 zeigt eine Prinzipdarstellung einer Vorrichtung 1 zur Herstellung eines durch Verspinnen wenigstens zweier einzelner Fasern 2a, 2b ausgebildeten Garns 3 gemäß einem weiteren Ausführungsbeispiel. Fig. 2 stellt eine schematische Aufsicht auf die Vorrichtung 1 dar. Fig. 4 zeigt eine vergrößerte Darstellung der in Fig. 2 gezeigten Einzelheit IV. 2 shows a schematic diagram of a device 1 for producing a yarn 3 formed by spinning at least two individual fibers 2a, 2b according to a further exemplary embodiment. 2 represents a schematic plan view of the device 1. 4 shows an enlarged view of the in 2 shown detail IV.

Anhand der Fig. 2, 4 ist zunächst ersichtlich, dass es im Rahmen des Verfahrens auch möglich ist, dass wenigstens drei Fasern 2a - 2c zur Ausbildung des Garns 3 miteinander versponnen werden. Die wenigstens drei Fasern 2a - 2c werden in dem Faserzusammenführungspunkt 12 zusammengeführt. Mithin können Garne 3 aus mehr als zwei Fasern 2a - 2c (Multifasergarne) hergestellt werden.Based on 2 , 4 It can first be seen that it is also possible within the scope of the method for at least three fibers 2a - 2c to be spun together to form the yarn 3 . The at least three fibers 2a - 2c are brought together in the fiber merging point 12 . Consequently, yarns 3 can be made from more than two fibers 2a-2c (multi-fiber yarns).

Das Verspinnen von wenigstens drei Fasern 2a - 2c zur Ausbildung eines Garns 3 kann, wie in den Fig. 2, 4 gezeigt, derart realisiert werden, dass wenigstens zwei Fasern 2a, 2c der Spinneinrichtung 6 gemeinsam über ein erstes Führungselement 5d und wenigstens eine weitere Faser 2b über ein zu dem ersten Führungselement 5d in einer Raumrichtung räumlich beabstandet angeordnetes weiteres Führungselement 5e zugeführt wird. Wenigstens zwei Fasern 2a, 2c können sonach über ein erstes Führungselement 5d zugeführt werden und wenigstens eine weitere Faser 2b über ein weiteres Führungselement 5e zugeführt werden. In diesem Zusammenhang sind gleich- oder ungleichmäßige Aufteilungen von Fasern 2a - 2c über eine gegebene Anzahl an Führungselementen möglich. Bei einer in Fig. 4 zusätzlich gezeigten beispielhaften Zuführung von vier Fasern (die vierte Faser ist strichliert angedeutet) und einer beispielhaften Anzahl an zwei Führungselementen 5d, 5e können zwei Fasern über ein erstes Führungselement 5d und zwei Fasern über ein zweites Führungselement 5e zugeführt werden oder drei Fasern über ein erstes Führungselement 5d und eine Faser über ein zweites Führungselement 5e zugeführt werden.The spinning of at least three fibers 2a - 2c to form a yarn 3 can, as in the 2 , 4 shown, can be implemented in such a way that at least two fibers 2a, 2c of the spinning device 6 are fed together via a first guide element 5d and at least one further fiber 2b via a further guide element 5e arranged spatially spaced apart from the first guide element 5d. At least two fibers 2a, 2c can thus be fed via a first guide element 5d and at least one further fiber 2b can be fed via a further guide element 5e. In this context, even or uneven distributions of fibers 2a - 2c are possible over a given number of guide elements. At an in 4 Additionally shown exemplary feeding of four fibers (the fourth fiber is indicated by dashed lines) and an exemplary number of two guide elements 5d, 5e, two fibers can be fed via a first guide element 5d and two fibers via a second guide element 5e, or three fibers can be fed via a first guide element 5d and a fiber are fed via a second guide element 5e.

Wenngleich in den Fig. nicht gezeigt, könnte das verfahrensgemäße Verspinnen von wenigstens drei Fasern 2a - 2c alternativ auch derart realisiert werden, dass die wenigstens drei Fasern 2a - 2c der Spinneinrichtung 6 über drei separate, in wenigstens einer Raumrichtung beabstandet voneinander angeordnete Führungselemente zugeführt werden, indem wenigstens eine erste Faser 2a über ein erstes Führungselement zugeführt wird, wenigstens eine zweite Faser 2b über ein zu dem ersten Führungselement in wenigstens einer räumlich beabstandet angeordnetes zweites Führungselement zugeführt wird und wenigstens eine dritte Faser 2c über ein zu dem zweiten Führungselement in wenigstens einer Raumrichtung räumlich beabstandet angeordnetes drittes Führungselement zugeführt wird. Jede Faser 2a - 2c kann sonach auch über ein separates Führungselement zugeführt werden.Although not shown in the figures, the spinning of at least three fibers 2a - 2c according to the method could alternatively also be implemented in such a way that the at least three fibers 2a - 2c are fed to the spinning device 6 via three separate guide elements arranged at a distance from one another in at least one spatial direction by at least one first fiber 2a being fed via a first guide element, at least one second fiber 2b being fed via a second guide element arranged at a spatial distance from the first guide element in at least one and at least one third fiber 2c being fed via a guide element to the second guide element in at least one Spatially spaced arranged third guide element is supplied. Each fiber 2a - 2c can therefore also be fed via a separate guide element.

In Fig. 4 ist schließlich noch angedeutet, dass es im Rahmen des Verfahrens auch möglich ist, dass wenigstens zwei Fasern 2a - 2c und wenigstens ein Filament 17 zur Ausbildung des Garns 3 miteinander versponnen werden. Die wenigstens zwei Fasern 2a - 2c und das wenigstens eine Filament 17 werden in dem Faserzusammenführungspunkt 12 zusammengeführt. Mithin können Garne 3 aus wenigstens zwei Fasern 2a - 2c und wenigstens einem Filament 17 hergestellt werden.In 4 Finally, it is also indicated that within the scope of the method it is also possible for at least two fibers 2a - 2c and at least one filament 17 to be spun together to form the yarn 3 . The at least two fibers 2a - 2c and the at least one filament 17 are brought together in the fiber merging point 12 merged. Consequently, yarns 3 can be produced from at least two fibers 2a-2c and at least one filament 17.

Das verfahrensgemäße Verspinnen von wenigstens zwei Fasern 2a - 2c und wenigstens einem Filament 17 kann derart realisiert werden, dass wenigstens zwei Fasern 2a - 2c der Spinneinrichtung 6 über zwei separate, in einer Raumrichtung beabstandet voneinander angeordnete Führungselemente 5d, 5e zugeführt werden und das wenigstens eine Filament 17 aus einem, insbesondere spulenartigen bzw. -förmigen, Filamentenspeicher 18, wie z. B. einer Filamentenspule, oder über ein zu den zwei separaten Führungselementen 5d, 5e separates drittes Führungselement zugeführt wird.The spinning of at least two fibers 2a - 2c and at least one filament 17 according to the method can be implemented in such a way that at least two fibers 2a - 2c are fed to the spinning device 6 via two separate guide elements 5d, 5e, which are spaced apart from one another in a spatial direction, and the at least one Filament 17 from a particular coil-like or -shaped, filament storage 18, such as. B. a filament spool, or via a separate third guide element to the two separate guide elements 5d, 5e.

Wenngleich in den Fig. nicht gezeigt, ist es neben der beschriebenen in einer quer zur Faserführungsrichtung verlaufenden Raumrichtung räumlich voneinander beabstandeten Anordnung von Führungselementen 5d, 5e alternativ oder ergänzend wenigstens prinzipiell auch möglich, dass wenigstens zwei in einer parallel zur Faserführungsrichtung verlaufenden Raumrichtung räumlich beabstandet voneinander angeordnete Führungselemente 5d, 5e verwendet werden. Mithin können wenigstens prinzipiell auch in Faserführungsrichtung versetzt angeordnete Führungselemente 5d, 5e verwendet werden.Although not shown in the figures, in addition to the described arrangement of guide elements 5d, 5e spatially spaced apart from one another in a spatial direction running transverse to the fiber guidance direction, it is alternatively or additionally possible, at least in principle, for at least two to be spatially spaced apart from one another in a spatial direction running parallel to the fiber guidance direction arranged guide elements 5d, 5e are used. Consequently, at least in principle, guide elements 5d, 5e that are offset in the fiber guide direction can also be used.

Im Rahmen des Verfahrens können Fasern 2a, 2b gleicher und ungleicher chemischer und/oder geometrischer und/oder physikalischer, insbesondere mechanischer, Eigenschaften zur Ausbildung des Garns 3 miteinander versponnen werden.As part of the process, fibers 2a, 2b of the same and different chemical and/or geometric and/or physical, in particular mechanical, properties can be spun together to form the yarn 3.

Im Rahmen des Verfahrens können sämtliche natürliche Fasern, d. h. z. B. Alpakafasern, Baumwollfasern, Kaschmirfasern, Mohairfasern, Seidefasern, Leinenfasern, Wollfasern, insbesondere Schurwollfasern, und/oder künstliche (synthetische) Fasern, d. h. z. B. Kunststoffasern, insbesondere Polyamidfasern, Polyesterfasern, Polypropylenfasern, Viskosefasern, zur Ausbildung des herzustellenden Garns miteinander versponnen werden können. Insbesondere sind auch Mischungen (einzelner oder mehrerer) natürlicher und (einzelner oder mehrerer) künstlicher Fasern denkbar. Bei den Fasern kann es sich, je nach Verfügbarkeit, um Endlos- oder Stapelfasern handeln.All natural fibres, e.g. H. e.g. B. alpaca fibres, cotton fibres, cashmere fibres, mohair fibres, silk fibres, linen fibres, wool fibres, in particular new wool fibres, and/or artificial (synthetic) fibres, d. H. e.g. B. plastic fibers, in particular polyamide fibers, polyester fibers, polypropylene fibers, viscose fibers, can be spun together to form the yarn to be produced. In particular, mixtures of (one or more) natural fibers and (one or more) artificial fibers are also conceivable. The fibers can be continuous or staple, depending on availability.

Auch eine (einzelne) Faser 2a, 2b kann aus wenigstens zwei chemisch und/oder geometrisch und/oder physikalisch unterschiedlichen Fasermaterialien gebildet sein bzw. wenigstens zwei chemisch und/oder geometrisch und/oder physikalisch unterschiedliche Fasermaterialien umfassen. Eine entsprechende demnach auch als Mischfaser (Mischroving) zu bezeichnende Faser 2a, 2b kann demnach z. B. aus einem ersten Fasermaterial (Rovingmaterial) und wenigstens einem weiteren Fasermaterial (Rovingmaterial) gebildet sein.A (single) fiber 2a, 2b can also be formed from at least two chemically and/or geometrically and/or physically different fiber materials or comprise at least two chemically and/or geometrically and/or physically different fiber materials. A corresponding one can therefore also be designated as a mixed fiber (mixed roving). Fiber 2a, 2b can therefore z.
