Abstract
Eine Vorrichtung zum Herstellen eines Scheinzwirnes enthält ein Streckwerk, welches an einer Ausgangsklemmlinie zwei nebeneinander laufende verstreckte Faserverbände einer Verdichtungszone darbietet. Im Abstand von der Ausgangsklemmlinie endet die Verdichtungszone mit einer einen Drallstopp bewirkenden Lieferklemmlinie, der ein die nunmehr verdichteten Faserverbände gemeinsam verdrehendes Drallorgan folgt. Die Verdichtungszone enthält einen mechanischen Verdichter, der zwei nebeneinander angeordnete und in Transportrichtung der Faserverbände sich verengende Verdichtungskanäle aufweist.An apparatus for producing a false twisting device comprises a drafting device, which presents at an output clamping line two juxtaposed drafted fiber bundles of a compression zone. At a distance from the output clamping line, the compression zone ends with a delivery stop line causing a swirl stop, which is followed by a swirl element that rotates the compressed fiber bundles together. The compression zone contains a mechanical compressor which has two compression channels arranged next to one another and narrowing in the transport direction of the fiber composites.
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen eines Scheinzwirnes, mit einem Streckwerk, welches an einer Ausgangsklemmlinie zwei nebeneinander laufende verstreckte Faserverbände einer Verdichtungszone darbietet, die im Abstand von der Ausgangsklemmlinie mit einer einen Drallstopp bewirkenden Lieferklemmlinie endet, der ein die nunmehr verdichteten Faserverbände gemeinsam verdrehendes Drallorgan folgt.The The invention relates to a device for producing a dummy pear, with a drafting system, which at a Ausgangsklemmlinie two next to each other running stretched fiber composites a compression zone, the distance from the Ausgangsklemmlinie ends with a swirl stop effecting delivery line, the a now dense fiber composites twisting together Swirl organ follows.
Scheinzwirne unterscheiden sich von echten Zwirnen dadurch, dass die Komponenten, aus denen der Scheinzwirn hergestellt ist, die gleiche Drehrichtung aufweisen wie der fertige Scheinzwirn. Beim echten Zwirn hingegen haben die den Zwirn bildenden Komponenten eine andere Drehrichtung als der fertige Zwirn. Scheinzwirne lassen sich dadurch herstellen, dass an einer Spinnstelle zwei Faserbänder oder Vorgarne verstreckt und in einem Arbeitsgang nach dem Verstrecken vor einer Dralleinrichtung zusammengeführt und gemeinsam verdreht werden.translucent threads are different from real plying in that the components, from which the false twist is made, the same direction of rotation exhibit like the finished apparent thread. By contrast, with the real thread the components forming the thread have a different direction of rotation as the finished thread. Pseudo-threads can be made by that stretched at a spinning station, two slivers or rovings and in one operation after stretching before a twisting device together and be twisted together.
Es hat sich gezeigt, dass dann, wenn in die genannten Komponenten sofort nach der Ausgangsklemmlinie des Streckwerks die Spinndrehung eingeleitet würde, in nachteiliger Weise an der Ausgangsklemmlinie für jede Komponente ein Spinndreieck auftreten würde, welches eine relativ breite Basis hätte. Dies liegt daran, dass die verstreckten Faserverbände, welche die Komponenten für den Scheinzwirn bilden, an der Ausgangsklemmlinie eine relativ große Breite aufweisen, während die eingeleitete Spinndrehung zu einem relativ kleinen Durchmesser führt. Spinndreiecke mit großer Basis enthalten Randfasern, die wenig oder nichts zur Festigkeit der entstehenden Fäden beitragen. Man ist daher bestrebt, durch Bündeln oder seitliches Verdichten der verstreckten Faserverbände die Basis der Spinndreiecke möglichst klein zu halten. Dadurch sollen Randfasern, die bei der Drehungserteilung nicht ordnungsgemäß eingebunden würden, weitgehend vermieden werden.It it has been shown that when in the components mentioned immediately after the Ausgangsklemmlinie the drafting introduced the spin rotation would, disadvantageously at the output clamping line for each component a spinning triangle would occur which would have a relatively broad base. This is because of that the stretched fiber composites, which the components for form the apparent thread, at the Ausgangsklemmlinie a relatively large width exhibit while the initiated spin rotation to a relatively small diameter leads. Spinning triangles with big ones Base contain edge fibers that have little or nothing to the strength the resulting threads contribute. One is therefore anxious, by bundling or lateral compaction the stretched fiber composites the base of the spinning triangles as possible to keep small. This is to edge fibers, which in the rotation distribution not properly integrated would be largely avoided.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zum Herstellen eines Scheinzwirnes zu schaffen, deren Verdichtungszone ohne jeglichen Unterdruck auskommt.Of the Invention is based on the object, an apparatus for manufacturing to create a mocking pear whose compression zone without any negative pressure gets along.
Die Aufgabe wird dadurch gelöst, dass die Verdichtungszone einen mechanischen Verdichter enthält, der zwei nebeneinander angeordnete und in Transportrichtung der Faserverbände sich verengende Verdichtungskanäle aufweist.The Task is solved by that the compression zone contains a mechanical compressor, the two juxtaposed and in the transport direction of the fiber composites itself narrowing compression channels having.
Zwar sind mechanische Verdichter im Anschluss an ein Streckwerk durch die WO 03/095 723 A1 Stand der Technik, jedoch ist dort keine Vorrichtung zum Erzeugen eines Scheinzwirnes offenbart.Though are mechanical compressors following a drafting system through WO 03/095 723 A1 prior art, but there is no device for generating a false twist.
Die beiden Verdichtungskanäle können vorzugsweise jeweils eine gekrümmte, den zugeordneten Faserverband umlenkende Auflagefläche aufweisen. Letztere kann durch eine sich in Transportrichtung des zugehörigen Faserverbandes bewegende Führungsfläche gebildet sein. Als Führungsfläche kommt beispielsweise der Umfang einer der Ausgangsklemmlinie zugeordneten Ausgangswalze des Streckwerks in Betracht. Die Führungsfläche kann dabei vom Verdichter tunnelartig überdeckt sein. Dabei ist es möglich, der Ausgangswalze außer der Ausgangsklemmlinie auch die Lieferklemmlinie direkt zuzuordnen.The both compression channels can preferably in each case a curved, Having the associated fiber structure deflecting bearing surface. The latter can by a in the transport direction of the associated fiber structure formed moving guide surface be. As a guide surface comes For example, the extent of one of the output terminal line assigned Outgoing roller of the drafting system into consideration. The guide surface can be from the compressor tunnel-like covered be. It is possible the output roller except the output terminal line also directly assign the delivery terminal line.
In besonders vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass sich die Verdichtungskanäle in Transportrichtung einander annähern. Dies führt zu dem Vorteil, dass bereits in einem kurzen Abstand nach der Lieferklemmlinie die beiden verstreckten und verdichteten Faserverbände sich zu dem Scheinzwirn vereinigen.In particularly advantageous embodiment of the invention is provided that the compression channels are approach each other in the transport direction. This leads to that Advantage that already at a short distance to the delivery nip line the two stretched and compacted fiber composites themselves to unite the false twist.
