Description

 DEVICE AND METHOD FOR KETTWIRKEN

The invention relates to an apparatus for warp knitting of weft fabrics having a weft transport for transporting weft yarn in the machine direction along a working plane spanned by the weft yarns, wherein the weft yarn transport comprises spaced apart transport means having machine direction movable transport hooks and a weft insertion apparatus for weft insertion transverse to the machine direction, wherein the weft yarns are alternately fed to the movable transport hooks of the spaced transport means by means of a weft thread driver of the weft insertion apparatus.

The invention further relates to a method of warp knitting in which a plurality of warp yarns juxtaposed in a common working plane are advanced in the machine direction, in which weft yarns are introduced into the area of the common working plane by means of a weft driver transverse to the machine direction in which the weft thread is transferred from the weft thread driver to a transport device of a weft transport for transporting the plurality of warp threads.

Generic devices and methods are known from the prior art, for example from DE 10 2007 004 315 A1, which describes a warp knitting machine.

However, such devices are often limited in their operating speed in that a weft insertion apparatus comprising a weft insertion carriage must be traversed transversely to warp threads for introduction of weft threads, in particular this weft insertion carriage must be constantly accelerated and decelerated, in order to carry out a corresponding traversing movement against the warp thread can.

BESTATIGUNGSKOPIE Furthermore, the weft threads run mostly over guide eyelets of the weft insertion carriage or the like, as a result of which the weft threads are subjected to a high mechanical load. This often has the consequence that individual filaments of the weft thread tear on or in and unfavorable case, which often leads to quality losses of the product to be manufactured.

The object of the invention is to further develop generic devices and processes and, in particular, to overcome the disadvantages mentioned above.

The object of the invention according to a first aspect of a device for warp knitting weft yarn goods with a weft transport for transporting weft yarn in the machine direction along a working plane spanned by the weft yarn, in which the weft yarn transport comprises spaced apart transporting devices, which are movable in the machine direction Transport hooks, and solved with a weft insertion apparatus for entry of weft yarns transversely to the machine direction, wherein the weft yarns are fed by means of a weft thread of the weft insertion alternately the movable transport hooks of the spaced transport means, and wherein the weft insertion apparatus continuously circulates.

The fact that the weft insertion apparatus rotates continuously, acceleration and braking operations can be omitted entirely, as is always the case for a reversal of direction in previously known from the prior art solutions.

In this respect, it is advantageous that the weft insertion apparatus continuously rotates in order to transfer the weft yarns alternately to a transport device of the spaced-apart transport devices of the weft thread transport.

Preferably, the present device without braking comes to a standstill of Weft insertion apparatus to pass the weft yarn alternately to a transport device of the spaced-apart transport means of the weft transport.

In contrast to previously known from the prior art solutions in terms of the general Kettwirkens means of a weft insertion productivity in the present solution is no longer or only negligibly limited by the inertia of moving masses, especially a conventional weft insertion carriage, since here the weft insertion apparatus continuously rotates , In this respect, the inertia of moving masses of a linear alternating movement in this regard no longer plays any role whatsoever.

In this respect, the present invention, compared to the prior art significantly increased working speeds or deposition speeds of weft yarn allows while reducing the Gamreibung between the weft and the weft thread driver. Advantageously, in this case an increase in the operating speed can be achieved by up to 200% compared to previous solutions with weft insertion carriage.

At the same time, the yarn friction in the present case can be reduced by at least 40%, in particular by almost 100%, compared with the coefficients of friction of conventional solutions between weft threads and a thread guide of a weft insertion carriage. The term "weft knitted goods" here describes all goods in which weft threads and warp thread can be arranged at any angle to each other and are connected by a meshing by knitting thread in the region of the so-called effective zone substantially slipping together.

The term "weft transport" describes any device which is suitable for transporting the weft threads in the machine direction. The term "machine direction" in the sense of the present invention describes the main transport direction of the device in which the weft threads, but also, for example, the warp threads in the direction of their longitudinal extent, can be transported, either continuously or intermittently. The warp threads can alternatively also be supplied later, for example shortly before an active unit.

In this context, the term "transversely to the machine direction" in the sense of the invention describes an orientation of the weft thread obliquely to a Kettfadenausrichtung. In other words, this also means layers and directions of the weft thread with respect to the warp threads, which deviate from a right angle.

The weft transport has at least two contested transport devices which extend in the machine direction and are designed such that the transport devices can bring about a forward movement in the machine direction, in particular on the weft thread. The transport facilities are equipped with transport hooks, which are movable in the machine direction.

The weft threads are placed around these transport hooks in order to be able to hold the weft thread in position relative to the warp threads at least until weft and warp threads are finally connected to one another at their crossing regions, in particular forfeited.

It is understood that these transport hooks can be designed manifold, for example, as a simple straight or curved pin elements, as needles, as hook-shaped elements or the like, wherein the transport hooks can be designed with a blunt or pointed end. The term "weft insertion apparatus" here a device is described by means of Which weft threads can be arranged individually or preferably grouped transversely to the machine direction with respect to the warp threads, so that warp thread and weft thread are ultimately arranged at an angle to one another.

"Grouped" refers to a multiplicity of weft threads which can be fed simultaneously with the weft insertion apparatus.

For the purposes of the invention, the term "weft thread driver" covers any means by means of which the weft threads can be guided individually or in groups along a feed path to the transport devices.

Such a weft thread driver can be designed differently here. Thus, for example, it may comprise passively or actively active driver elements acting on the weft threads.

For example, a passively acting driver element can already be realized by a hook element or the like.

By contrast, an actively acting driver element is characterized, for example, by the fact that weft threads are actively grasped and held.

In this context, it may also be advantageous if the weft thread driver comprises more than one driving element which is passive and / or active on the weft threads.

Furthermore, the present weft insertion apparatus is still characterized by driving means which continuously circulate on the weft insertion apparatus in the sense of the invention.

Suitable drive means can be configured in many ways, such as revolving belt elements or chain elements. Preferably, the driving means are self-contained, endlessly configured. Expediently, the drive means provided here take up at least one weft driver, but preferably a plurality of mutually spaced weft drivers.

In this case, the weft thread runner or the weft thread runners then run continuously with the drive means according to the invention.

In this respect, it is advantageous if the weft insertion apparatus comprises at least one curved path along which the drive centers extend and also move during operation of the weft insertion apparatus.

As a result, the weft driver also moves along such a curved path.

It is understood that the present curved path can be formed almost arbitrarily. A preferred embodiment provides that the curved path is realized as a stretched circular path, wherein the stretched circular path in the sense of the invention is characterized by opposing substantially arcuate Bahnabschnite the curved path, which are spaced by substantially straight Bahnabschnite the curved path from each other. Here, the substantially straight Bahnabschnite can also be curved.

A stretched circular path can also be described as an endlessly closed trajectory with a continuous tangential velocity within the meaning of the invention.

In any case, the term "curved path" in the context of the invention preferably describes an arbitrarily configurable path of movement along which the weft thread driver moves in order to transfer weft thread to the weft transport and in particular to transport hooks of the transporting means of the weft transport by means of the weft insertion apparatus. In the present case, the term "work plane" describes a region of the device in which the weft threads lie in the device, or else warp threads and weft threads can be joined together. This area is a substantially planar part of the device.

Here, the working level is essentially determined by the weft thread running side by side.

In this case, the working plane preferably extends in width preferably from a transport device of the weft thread transport to a transport device of the weft transport spaced therefrom, wherein the transport devices may belong to the extent of the working plane. In the length, the working level can extend from a transport infeed to a transport outfeed.

The object of the invention according to a second aspect of a device for warp knitting of weft yarn goods with a weft transport for transporting weft threads in the machine direction along a working plane spanned by the weft threads, wherein the weft transport comprises spaced apart transport means having transportable transport hooks in the machine direction , and with a weft insertion apparatus for entry of weft thread transversely to the machine direction, wherein the weft yarns are fed by means of the weft insertion apparatus alternately the movable transport hooks of the spaced transport means, and wherein the weft insertion apparatus comprises at least two weft insertion means, wherein the weft insertion apparatus is arranged such that a first weft insertion device of the weft insertion apparatus only with a first transport device of the weft transport and another Weft insertion device of the weft insertion apparatus interacts only with the other transport device of the weft transport.

In contrast to the prior art with one above the weft thread through In the tensioned working plane traversing weft insertion car, the present invention goes a completely different way, namely with a weft insertion apparatus, which does not seem to increase by a single weft insertion carriage, but by two weft insertion devices, whereby the structural complexity of existing device even seems to increase.

In any case, this solution of the present invention compared to the prior art significantly increased operating speeds or storage speeds of weft yarns allows while reducing the Gamreibung between the weft and the weft yarn driver.

Advantageously, in this case an increase in the operating speed can be achieved by up to 200% compared to previous solutions with weft insertion carriage.

At the same time, the yarn friction in the present case can be reduced by at least 40%, in particular by almost 100%, compared to the coefficients of friction of conventional solutions between the weft thread and a thread guide of a weft insertion carriage.

Conveniently, the weft insertion apparatus comprises two weft insertion devices, each of the weft insertion devices having a curved path.

It is likewise advantageous if the weft insertion apparatus comprises at least one continuous weft thread catcher.

Preferably, the entry of the weft threads by means of two counter-rotating, continuously moving means of propulsion takes place.

The drive means are preferably arranged in such a way that weft thread is guided from a region of the transport means, preferably arranged centrally in the transport means, in particular a weft thread presentation device, to a respective transport means of the transport means. The weft threads are in this case alternately coupled to one of the two driving means or a related Schussfadenmitnehmer. The object of the invention is also provided, according to a third aspect, by a device for warp knitting of warp knit goods with a weft transport for transporting weft yarn in the machine direction along a working plane spanned by the weft threads, in which the weft transport comprises transport devices spaced apart from one another, which have machine-directional transport hooks, and with a weft insertion apparatus for entry of weft yarn transversely to the machine direction, wherein the weft yarns are fed by means of the weft insertion alternately the movable transport hooks of the spaced transport means, and wherein the weft insertion relative to the plane spanned by the weft threads working plane arranged inclined is. If the weft insertion apparatus is inclined relative to the working plane spanned by the weft thread, it is structurally very easy to supply weft threads starting from a central weft thread feed to the transporting devices of the weft thread transport spaced apart from one another.

Advantageously, in this case an increase in the operating speed can be achieved by up to 200% compared to previous solutions with weft insertion carriage.

At the same time, the yarn friction in the present case can be reduced by at least 40%, in particular by almost 100%, compared to the coefficients of friction of conventional solutions between the weft thread and a thread guide of a weft insertion carriage.

If the weft insertion apparatus has at least two continuously rotating drive means, each with at least one weft thread driver, the weft threads can be supplied with two transport devices of the weft thread transport in a structurally simple manner. Insertion of weft thread, in particular from a weft threading device, to the weft insertion apparatus, in particular to the weft thread follower thereof, can be carried out particularly reliably if the weft insertion apparatus has at least two continuously rotating means of drive, each with at least one insertion aid for inserting weft thread into the at least one weft thread catcher ,

An advantageous embodiment variant provides that the weft insertion apparatus is set up in such a way that a driving means and / or a weft thread driver at reversing positions of a curved path, preferably at each point of the curved path, at the same speed or with respect to the maximum speed by at most 90% - reduced speed revolves.

Preferably, the driving means and / or weft thread drivers and / or inserting aids or the like run around at the same speed.

By virtue of the drive means and / or weft drivers and / or insertion aids or the like circulating at speeds which are reduced by at most 90% compared with the maximum speed, it is ensured that the speed need not be reduced to zero m / s, as is the case with conventional ones Weft insertion carriage is absolutely necessary. This alone can achieve a higher operating speed compared with the prior art.

The term "speed" specifically covers the tangential velocity.

Furthermore, it is advantageous if the weft insertion apparatus has at least two mutually different curved paths. As a result, the weft threads can be supplied in a structurally simple manner alternately to the transport devices of the weft thread transport which are spaced apart from one another.

Optionally, two curved paths can also be designed mirror-symmetrically. If appropriate, with a suitable design, this is also possible with a single curved track, if the weft threads are inserted in a suitable manner by the weft threading device and transferred to the transport devices of the weft transport.

If the weft insertion apparatus has at least one changeable curved path, the weft insertion apparatus can be adapted to different requirements. Considered here, for example, to be produced differently weft knit goods or the like.

Ideally, the variable curved path can be formed to an ideal curved path, whereby a particularly precise operation can be achieved.

Another very advantageous embodiment provides that a curved path of the weft insertion apparatus and the work plane spanned by the weft thread an inclination angle of more than 10 °, more than 25 ⁰ or more, preferably 45 °, with each other, whereby the weft in a compact design from a central weft supply, in particular from a weft thread presentation device, can be guided to the transport means of the weft transport.

In a specific embodiment, depending on the customer request, the angle of inclination be up to 180 ^0, so that a curve path of the weft insertion apparatus or a weft insertion means is arranged parallel or plane-parallel to the working plane.

In this case, the overall height of the device can be significantly reduced if a weft insertion apparatus, which is arranged inclined about a first axis of inclination relative to the working plane spanned by the weft threads, is tilted about a further tilting axis relative to this working plane.

In this case, the tilting axis and the tilting axis are different from one another, in particular with regard to their spatial positions. Furthermore, it is advantageous if the weft insertion apparatus is arranged with respect to the weft thread transport with an angle of attack a F 90 °, whereby structurally simple multiaxial laying of threads can be achieved.

If the weft insertion apparatus is arranged to be rotatable about a pitch axis relative to the weft thread transport, the pitch axis being arranged perpendicular to the weft transport, in particular to the working plane, the variability with regard to the arrangement of the warp and weft threads relative to one another can be achieved with the present device be chosen almost popular.

In any case, it is possible with the measures described above that the weft yarns and the warp yarns can be aligned with each other in a structurally simple manner with a transfer or insertion angle a F 90 °, whereby it is easily possible to transpose threads in a multiaxial manner.

As already mentioned above, weft threads on the weft insertion device or its weft insertion devices can be inserted reliably and thus advantageously when the device is also characterized by a weft threading device, by means of which weft threads into the weft insertion device, in particular into a weft insertion device Weft thread driver of the weft insertion apparatus can be inserted.

In this regard, it is advantageous for the weft insertion apparatus, with regard to its longitudinal extension from the weft threading device to a transport device of the weft insertion device, in particular weft insertion devices of the weft insertion device, to extend in each case from the weft threading device to one transporting device of the two spaced-apart transporting devices with respect to their respective longitudinal extent. As a result, centrally provided weft threads can be moved very easily and at extremely high speed in the direction of weft transport. A further embodiment, which is also advantageous independently of the other features of the invention, provides a transfer device for transferring weft thread from the weft insertion apparatus to the weft transport, wherein the transfer device is movably mounted with respect to more than one spatial axis. By means of a spatially movable transfer device of this type, it is possible to reliably transfer the weft threads from the present weft insertion device or weft insertion devices to the transport devices even at very high working speeds.

This alone can advantageously further develop a generic device, so that this feature combination is already advantageous without the other features of the invention.

It is likewise particularly expedient for the transfer device to be arranged so as to be rotatable about a pivot axis relative to the weft thread transport, wherein the pivot axis is arranged perpendicular to the weft thread transport, in particular to the working plane. As a result, the respective transfer device can always be positioned optimally with respect to the associated weft insertion device of the weft insertion apparatus on the one hand and with respect to the associated transport device of the weft transport in order to be able to reliably effect multi-axial displacements of threads.

In this respect, it is also advantageous if the transfer device is arranged so as to be rotatable about a pivot axis relative to the weft insertion apparatus, the pivot axis being arranged perpendicular to the weft transport, in particular to the working plane.

Cumulatively or alternatively, it is advantageous if the transfer device is movable in translation in the machine direction or counter to the machine direction, independently of the weft thread transport and / or the weft insertion apparatus, whereby the weft threads are structurally simple with a transfer point. or insertion angle a F 90 ° can be aligned so that even multi-axial transfers of threads are easily possible.

It should be mentioned at this point that, cumulatively or alternatively, the entire weft insertion apparatus can also be moved translationally in the machine direction or counter to the machine direction in order to achieve the effects explained above. However, the masses to be moved are higher.

A variant which is also particularly advantageous independently of the other features of the invention provides a transfer device for transferring weft threads from the weft insertion apparatus to the weft thread transport, wherein the transfer device comprises a weft wiper for discharging the weft thread from the weft thread catcher to a transfer device for transferring weft threads from the weft threading device Weft insertion apparatus to the weft transport has. Due to the additional weft scraper, an even more reliable transfer of the weft thread from the weft thread catcher to the transfer device succeeds.

Particularly effectively, the weft scraper can interact with a weft thread when the weft scraper is arranged at a terminal of the transfer device.

Basically, the weft scraper can be of different shape.

It is essential, however, that the weft wiper has a weft contact surface with which the weft wiper can interact with a weft thread.

In this context, it is advantageous if the weft scraper is designed such that the weft contact surface faces a terminal space of the clamp. Preferably, this weft contact surface protrudes at least partially into the clamp or its terminal space in order to be able to come into good contact with the weft thread.

Advantageously, the weft scraper comprises a sliding surface, along which the weft thread can slide out of the clamp, wherein in particular the sliding surface can be structurally embodied simply by the weft contact surface of the weft scraper.

By means of the transfer device described above, generic devices can also be further developed independently of the other features of the invention.

Just as independent of the other features of the invention, it is advantageous if a distance between adjacent, in particular between two immediately adjacent, transfer devices can be variably adjusted. As a result, in particular the weft thread density on the finished product can be easily determined.

It is also expedient if transfer devices are individually controllable with regard to their positioning relative to each other, in order to variably set the distances between adjacent transfer devices. By such a control, it is possible almost at any time to set intervals between the individual transfer devices.

A corresponding control technology can be easily implemented in existing control and / or regulating devices of the device. Or it can be provided without further ado an additional control and / or regulating device.

Furthermore, it is advantageous to provide a varying device for setting individual distances between transfer devices on the device 1. A corresponding varying device can be designed differently. For example, it can be equipped with corresponding displacement units.

It is understood that the device for this purpose can also comprise via corresponding individually controllable traversing carriage, which are movably mounted in corresponding rail assemblies.

On such traversing transfer devices can be arranged, either individually, in pairs or in groups, with a few transfer devices or traversing the highest variability can be achieved, but also the highest design effort must be operated. Constructively advantageous, such traversing carriages can also be formed by the transfer devices.

In any case, devices of the generic type can advantageously be further developed independently of the other features of the invention by means of the present variation device, so that the features described in this context can also justify an independent invention.

So that the weft threads can always be handled reliably on the device, it is particularly expedient if the device is cumulative or alternatively characterized by a weft thread tensioning device, by means of which weft thread can be prestressed for insertion into a weft thread catcher of the weft insertion apparatus.

A further improvement in terms of reliable handling of weft threads can be achieved if the weft thread catcher has an additional weft thread safety device by means of which a weft thread can additionally be temporarily fixed to the weft thread catcher. In particular, it is advantageous if this is an actively operating or acting weft thread captive.

It is advantageous if the additional weft thread captive is self-closing, which structurally simple active weft captive can be realized on the present device.

As a result, a high level of security can be achieved at the additional weft thread captive.

In particular, in the present case, a very reliably actively operating weft thread take-up can be achieved. By means of such an active entrainment device, the entrainment of a weft thread compared to hitherto passively active or operating entrainment elements is again significantly improved.

Such a weft yarn captive can be realized structurally simple on the weft insertion apparatus if the additional weft yarn captive has a driver element, in particular a hook-shaped driver element, and an additional clamp element, wherein in particular the additional clamp element is arranged prestressed relative to the driver element.

Such driver elements, in particular in the form of hooks, are already present, so that only an additional clamping element has to be integrated in order to construct the present weft thread safety lock in a constructively simple manner.

In addition, subsequent features mentioned in particular in connection with a weft thread eye are advantageous independently of the other features of the invention.

Thus, another embodiment which is likewise very expedient provides that a weft eye is provided with a plurality of eye holes, eyelets being connected to one another. are arranged individually displaced. By means of the individually displaceable eye-holes, it is advantageously possible, inter alia, to produce almost any desired weft pattern in the loop.

In this case, for example, only individual eye holes or all eye holes can be arranged individually displaceable, in particular to each other.

In order to be able to provide such displaceable eye holes in the present device in a constructively simple and defined manner, it is advantageous if eye holes have displaceable eye hole elements.

Such eyelet elements can be provided structurally simply as displaceable sliding blocks, with such sliding blocks being able to be purposefully positioned in corresponding slide guides or guide tracks. Advantageously, slide guides can be arranged superimposed.

So eye hole elements can be moved along about one, two or more axes who the.

Such displacement axes can be structurally easily implemented by appropriately arranged link guides. In order to be able to realize the eye-hole elements in a compact manner on the present device, it is advantageous if the eye-hole elements and in particular the eye-holes are arranged on a single weft eye.

In this respect, a preferred embodiment variant also provides that the eye holes and in particular the displaceable eye hole elements are arranged movably relative to one another on the weft thread eye. Moreover, it is generally advantageous if the weft eye can be moved independently of his Augenlöchem or eye hole elements. As a result, even more variations can be made available.

Such a weft eye can be of various shapes. For a related embodiment, reference is made at this point in particular to the exemplary embodiments shown in FIGS. 20 and 74 to 77, without describing the features or combinations of features realized there again.

According to a fourth aspect, the object of the invention is also achieved by a method for warp knitting of weft knitted goods in which a multiplicity of weft threads arranged side by side in a working plane are moved forwards in the machine direction, with which weft thread being transverse to the weft thread Machine direction are introduced into the region of the working plane, and in which the weft thread is transferred from the weft thread to transport means egg nes weft transport for transporting the plurality of weft, wherein the method is characterized in that the weft thread follower continuously rotates on an elongated circular path.

Characterized in that the Schussfadenmitnehmer continuously circulates on an elongated circular path, the Schussfadenmitnehmer need not be unnecessarily slowed down when feeding the weft threads to the transport means of the weft transport, so that in the present case higher operating speeds can be achieved.

In this respect, it is advantageous if a speed v of the weft thread driver is always at a reversal point of the extended circular path between a forward movement and a backward movement or vice versa v> 0. In this respect, a higher operating speed can be ensured compared with conventional generic devices. The present method can be designed particularly favorably when the weft yarner rotates at reversal positions of the stretched circular path, preferably at each point of the elongated circular path, at the same speed or at a speed which is reduced by at most 90% with respect to the maximum speed.

By virtue of, for example, driving means and / or weft drivers and / or insertion aids or the like circulating at speeds which are reduced by at most 90% with respect to the maximum speed, it can be ensured that the speed is not reduced to zero m / s, as it is is mandatory in conventional weft insertion car.

The term "speed" specifically covers the tangential velocity.

A particularly quiet and easily controllable operation of a device for warp knitting of weft knitted goods can be achieved if the weft thread taker rotates at a constant speed.

If the weft thread driver only comes into operative contact with the weft threads temporarily, namely during a forward movement to the transport device, then in particular the mechanical load on the weft threads can be considerably reduced.

The same can be achieved if the weft thread driver moves together with the weft yarn disposed thereon in a forward movement from a thread transfer device to the transport device and the weft thread catcher transfers the weft threads to the transport device alone, ie without weft threads, in a backward movement of the weft thread Transport device moved back to the Fadenvorleger- device to take along weft again temporarily. In addition, corresponding weft insertion devices of the weft insertion apparatus or related weft thread drivers can be operated at higher speeds.

It has been determined in experiments that the process can be performed even more reliable when weft and insertion aids of two with each other interacting weft insertion means are alternately engaged with each other to supply weft on the one hand by means of a first weft insertion device of a first transport device and on the other hand by means of a further weft insertion device of a further transport device.

All of the solutions described here are based on an optimization of the movement guidance for weft insertion or weft transport or for weft thread feeding.

Advantageously, in addition to the advantages already mentioned above, critical contact between the weft thread and the weft thread driver can also be reduced almost punctually and on edge regions near the transport means of the weft yarn transport.

Further advantages, which are to be mentioned again here with the present invention, on the one hand are a very high production speed with increased energy efficiency. This is due in particular to the fact that no energy expenditure has to be used for braking or acceleration processes, as in the case of traversing linear movements of a weft insertion carriage known from the prior art.

On the other hand, attention should be drawn at this point to the particularly high level of yarn sparing of the weft thread, since frictional contact between the weft thread and the present weft thread take-up takes place only in a locally very limited area of a weft thread section. This is especially true when achieving an ideal curved path or trajectory.

It should be noted that in the context of the present patent application indefinite articles and indefinite numbers such as "a ...", "two ...", etc. should be understood as a rule as at least-information, so as "at least one ... "," at least two ... "and so on, except in the context or the context The concrete text of a particular passage shows that about there only "exactly one .." exactly two ... ", etc. should be meant.

It should be mentioned at this juncture that in the context of the present patent application the expression "in particular" should always be understood to mean that this expression introduces an optional, preferred feature. The term is not to be understood as "and" and not as "namely".

It goes without saying that the features of the solutions described above or in the claims can optionally also be combined in order to be able to implement the presently obtainable advantages and effects in a correspondingly cumulative manner

Each of the transport devices 7 and 8 has a multiplicity of transport hooks 9 (numbered only by way of example), to which the weft threads 6 are transferred from the weft insertion apparatus 3 to the weft transport 2. The weft insertion apparatus 3 comprises two weft insertion devices 15 and 16, by means of which the weft threads 6 are introduced transversely with the laying direction 17 into a working plane 18 of the device 1.

The two weft insertion devices 15 and 16 each have an encircling drive means 20 (numbered only by way of example) in the form of a belt drive (not separately numbered), the respective belt drive being endlessly along a curved path 22 on the weft insertion apparatus 3 by means of pulleys 21 (numbered only by way of example) circulates.

The drive means 20 of the two weft insertion devices 15 and 16 have an opposite direction of rotation 23 (numbered only as an example).

By means of the pulleys 21, reversing layers 24 are formed on the cam track 22.

Each of the drive means 20 is equipped with at least one weft thread driver 25 and with insertion aids 26 for inserting weft thread 6 into the at least one weft thread driver 25.

The two weft insertion devices 15 and 16 each have a longitudinal extent 27.

In order for a transfer of the weft thread drivers 25 of the respective weft insertion devices 15 and 16 to the transport hooks 9 to function reliably even at very high operating speeds, the device 1 has a transfer device 30 for transferring weft thread 6 from the weft insertion apparatus 3 to the weft insertion device 3. 2, wherein the transfer device 30 is movably mounted with respect to more than one spatial axis 31, 32 (see in particular from FIG. 32), namely translationally at least with respect to the spatial axis 31 and rotationally at least with respect to the further spatial axis 32.

The weft insertion devices 15 and 16 and thus essentially also the weft insertion apparatus 3 are arranged opposite to the working plane 18 in each case about an inclination axis 34 and inclined by an inclination angle 35 in the device 1.

The weft threads 6 are here provided by weft threads 38 and always biased by means of a weft thread tensioning device 39 before the weft threads reach a weft thread laying device 40, from which they are inserted into the respective weft thread tappets 25.

In this case, the weft thread driver 25 comes into operative contact only temporarily with the weft threads 6, namely during a forward movement 43 to the respective transport device 7 or 8 of the weft thread transport 2, but not during a backward movement 44.

While in the exemplary embodiment according to FIGS. 1 and 2 the weft yarn carriers 25 are still designed as fixed driver elements 47, the weft yarn drivers 25 are designed as rotatable roller elements 48 in the exemplary embodiment shown in FIG.

Otherwise, the two exemplary embodiments of Figures 1 and 2 on the one hand and Figure 3 on the other hand identical.

According to FIGS. 4 to 9, the basic principle of operation of the device 1 is explained, with FIGS. 4, 6 and 8 on the left each showing a front view of the device 1 and FIGS. 5, 7 and 9 each showing the corresponding top views. FIGS. 4 and 5 show how the weft thread 6 is inserted by the weft threading device 40 with the aid of the insertion aids 26 of the first weft insertion device 15 into the weft thread catcher 25 of the second weft insertion device 16. This takes place in an insertion region 50 of the first ends 51 of the weft insertion devices 15 and 16, respectively.

FIGS. 6 and 7 show how the weft yarns 6 are guided by means of the second weft insertion device 16 to the transport hooks 9 of the second transport device 8, while the insertion aids 26 of the second weft insertion device 16 are again moved to the insertion region 50. At the same time, the weft thread carrier 25 is moved to the insertion region 50 on the first weft insertion device 15 so that it can cooperate with the insertion aids 26 of the second weft insertion device 16 in order to reliably insert the weft threads 6 into the weft thread catcher 25.

FIGS. 8 and 9 show how the weft yarns 6 in a transfer area 52 of the second weft insertion device 16 are transferred from the weft thread driver 25 to the transfer device 30 on the second transport device 8.

According to FIG. 10, the insertion of a weft thread into the weft thread driver 25 is shown in greater detail again, the illustration being self-explanatory. weft

6 are inserted from the weft threading device 40 by means of the inserting helix 26 on the second weft insertion device 16 into the weft thread guide 25 on the first weft insertion device 15.

According to FIGS. 1 1 and 12, it is once again shown how a weft thread 6 is guided in a depression 53 of a first insert part 54 (Zwille) of the insertion aid 26 and is fed to the insertion region 50.

According to FIGS. 13 and 14, it is shown how the insertion aid 26 and the weft thread taker 25 are always brought into overlap. According to FIGS. 15 to 18 it is shown how the weft thread 6 is pressed by a second insert part 55 of the insertion aid 26 into the weft thread driver 25 in order to ensure a secure insertion even at very high working speeds.

FIGS. 19 and 20 show a further exemplary embodiment of the device 1, in which the two weft insertion devices 15 and 16 are each equipped both with a multiplicity of weft thread drivers 25 and with a large number of insertion aids 26. In this way, it is ensured that during a weft yarn transfer (see below on the right) of the weft thread 6 from the second weft insertion device 16 further up the weft thread 6 is already inserted again into a weft yarn guide 25.

In this case, it is decided by means of the position of the weft threading device 40 whether the weft thread 6 is inserted at the weft thread guide 25 located in the insertion region 50 or not.

For this purpose, the weft tipping device 40 has a weft eye 59 translationally displaceable in the direction of movement 58 (see FIG. 20), by means of which the weft threads 6 can be correspondingly deflected above the insertion region 50, if insertion of the weft threads 6 should be skipped. A deflection in the direction of movement 58 of the weft thread eye 59 takes place here by means of a cam 60 along which a follower roller 61 of the weft thread eye 59 rolls off.

According to FIG. 21, a further exemplary embodiment of the device 1 is shown, in which each of the two weft insertion devices 15 and 16 has in each case a multiply deflected propellant 20. The driving means 20 are in this case selected to be so long that per driving means 20 two weft yarn guides 25 and two insertion aids 26 can be used. The distances 63 between the weft yarn guide 25 and the insertion aids 26 are designed so that insertion can always be done at the right time. According to FIG. 22, a further exemplary embodiment of the device 1 is shown, in which the weft insertion apparatus 3 also comprises an adjustment mechanism 65, by means of which the cam tracks 22 of the two weft insertion devices 15 and 16 can be varied almost arbitrarily, as a result of which Effective width 66 of the device 1 can be varied. The effective width 66 here is for example 1320 mm.

This embodiment shows a real belt configuration with eight weft thread elements, namely four weft thread drivers 25 and four insertion aids 26 each.

Figures 22 and 23 show a further embodiment of the device 1, in which the cam tracks 22 of the two weft insertion means 15 and 16 are formed by the number and location of the individual pulleys 21, wherein the section A of Figure 23, the real movement 67 and the ideal circular path 68 shows.

In this exemplary embodiment, the pulleys 21 each have a belt pulley axis 70 which comprises bearings 71 located outside the pulley 21, as illustrated in FIG. As a result, the pulleys 21 can be adjusted in a proportionate manner.

According to FIG. 25, a further exemplary embodiment of the device 1 is shown, in which the cam track 22 is predetermined by means of a guide rail 73, as a result of which belt slides 21 can also be dispensed with.

Referring to FIG. 26, another embodiment of the device 1 is shown, in which the weft biasing device 39 has a tension roller 75 which can be adjusted by means of a cam 76 on which a follower roller 77 can roll off, the follower roller 77 on a lever 78 the tension roller 75 is arranged. The lever 78 is rotatably mounted in a rotary bearing 79. The weft yarns 6 are fed to the tensioning roller 75 via a deflection roller pair 80 and discharged again. FIG. 27 shows an alternative weft thread tensioning device 39 for the device 1, in which case the tensioning roller 75 pretensions the weft threads 6 with the aid of a tension spring 81.

According to FIG. 26, a further exemplary embodiment of the device 1 is shown, in which a compensation of the offset time of the weft yarn carrier 25 and insertion aids 26 with respect to the two weft insertion devices 15 and 16 can be achieved by means of a gear 83.

With the exemplary embodiment of the device 1 shown in FIG. 29, the effective effective width can be varied by an additional amount 85.

Figures 30 and 31 show a further exemplary embodiment of the device 1, in which the weft insertion apparatus 3 is tilted in addition to the inclination angle 35 (see Figure 2) about a tilt axis 87 relative to this working plane 18, whereby a reduction in height by the amount 88 can be achieved can.

With the figures 32 to 57, the structure and the function of Übergabeeinrichtun conditions 30 are shown. FIGS. 32 to 33 show an embodiment of the device 1 with the transfer device 30, wherein the transfer device 30 comprises a clamp 90, an ejector 91, a hook 92 and a linear bearing 93. In this case, the transfer device 30 can, on the one hand, move linearly along the spatial axis 31 and, on the other hand, rotate about the further spatial axis 32. FIG. 33 is an illustration of the transfer device 30 according to the viewing direction 94.

FIGS. 34 and 35 show the beginning of how the weft thread 6 is transferred to the transfer device 30 by means of the weft thread driver 25. For this purpose, the weft thread 6 runs farther and farther into the clamp 90, as can be clearly seen in FIGS. 36 and 37, as a result of which the clamp 90 is opened by the weft thread 6.

In this case, the weft thread 6 is released from the weft thread 25.

Subsequently, the weft yarn 6 jumps into the hook 92, so that the weft yarn 6 is finally removed from the weft yarn guide 25 and held on the transfer device 30 (see Figures 38 and 39).

The weft thread 6 thus held in the hook 92 is then transferred further to a transport hook 9, as shown in FIGS. 40 and 41.

According to FIGS. 42 to 49, it is shown how a second weft thread section of the weft thread 6 is removed from the transfer device 30 by means of an ejector movement 95 of the ejector 91 and to the transport hooks 9 of the weft thread transport 2 is transferred.

According to FIGS. 50 to 57, it is once again shown in other perspectives how the second weft thread section of the weft thread 6 is removed from the transfer device 30 by means of an ejector movement 95 of the ejector 91 and transferred to the transport hooks 9 of the weft transport 2.

A further exemplary embodiment of the device 1 is shown in FIGS. 58 to 63, reference being made to the above description with regard to the explanation of this further exemplary embodiment in order to avoid repetition. In this further exemplary embodiment, the entire weft insertion apparatus 3 is arranged such that it can be rotated out of an otherwise conventional rectangular arrangement, as shown, for example, in the exemplary embodiment according to FIG.

In particular, according to the illustrations according to FIGS. 59, 61, and 63, it can be clearly seen that the relevant rotation of the weft insertion apparatus 3 around the z axis drawn there, also referred to as the setting axis, has taken place which is perpendicular to the working plane 18 of FIG Device 1 runs.

This means that the weft insertion apparatus 3, in particular with respect to the transport means 7 and 8 of the weft thread transport 2, and thus also with respect to the machine direction 4, has an angle of attack a F 90 °.

More precisely, therefore, the individual weft insertion devices 15 and 16 of the weft insertion apparatus 3 each have an associated angle of attack a F 90 ° (only indicated with respect to the weft insertion device 15) relative to the weft thread transport 2.

The above-mentioned features mean that the individual weft threads 6, which are arranged by means of the weft insertion apparatus 3 with respect to the weft thread transport 2 and are transferred to the two transport means 7 and 8, are inserted into the working plane 18 with a corresponding transfer or insertion angle α F 90 ° and against the warp thread 5 can be arranged.

As a result, multiaxial transfers of threads can be achieved with the present device 1 in a structurally extremely simple manner, which considerably extends the versatility of use of the present device 1.

Thus, the individual weft thread 6 of the weft thread take-up 25 of the weft insertion devices 15 and 16 particularly reliable to the transfer device 30th can be transferred, the transfer device 30 has a swivel angle ß relative to the machine direction 4.

In this respect, to transfer the weft thread 6 to the transport hooks 9 of the respective weft insertion device 15 or 16, the transfer device 30 is arranged with the swivel angle β relative to the respective transport device 7 or 8, the swivel angle β = 90 ° -a.

In addition, the respective transfer device 30 can also be pivoted independently of the weft insertion apparatus 3 about a pivot axis 100 relative to the weft transport 2 to pass the weft threads 6 also reliable from the transfer device 30 to the transport hooks 9 of the weft transport 2 or to insert there.

Thus, the transfer device 30 in the acquisition of the weft 6 of the weft yarn 25 with respect to the machine direction 4 and the weft transport 2 a pivot angle ß 0 °, as shown schematically in particular according to the illustration of FIG.

During the transfer from the transfer device 30 to the weft transport 2, the swivel angle is preferably set at .beta. = 0.degree., As is schematically illustrated in the illustration according to FIG. 63.

In this respect, the transfer device 30 is not only pivotable with respect to the weft insertion device 3 or its weft insertion devices 15 and 16, but also with respect to the weft transport 2 or its transport devices 7 and 8; and preferably independently.

In the present construction of the further exemplary embodiment, the respective transfer device 30 is for example pivotally attached to the weft insertion apparatus 3. The illustrations according to FIGS. 58 and 59 show how the weft threads 6 with the weft thread drivers 25 of the second weft insertion device 16 are moved in the direction of the second transport device 8 of the weft thread transport 2. In this case, the weft threads 6 have already been transferred from the weft thread drivers 25 of the first weft insertion device 15 to the first transport device 7.

The representations according to FIGS. 60 and 61 show the transfer of the weft threads 6 to the transfer device 30, the latter being arranged for this purpose with a swivel angle β F 0 °, in particular with respect to the machine direction 4.

The representations according to FIGS. 62 and 63 finally show the transfer of the weft thread 6 from the transfer device 30 to the transport hooks 9 of the second transport device 8, for which purpose the transfer device 30 is given away in such a way that the swivel angle β = 0 °, so that the transfer device 30 is aligned parallel to the individual transport hooks 9 of the second transport device 8.

Referring to Figures 64 to 70, another embodiment of the device 1 is shown, reference being also made to the above description with regard to the explanation of this other exemplary embodiment in order to avoid repetition.

In this other embodiment, the entire weft insertion apparatus 3 is arranged at right angles to the weft thread transport 2, as shown, for example, with respect to the exemplary embodiment according to FIG. In order nevertheless to be able to make multiaxial transfers of threads, as in the case of the above-described further exemplary embodiment (see FIGS. 58 to 63), the transfer devices 30 assigned to the transport devices 7 and 8 are arranged so as to be displaceable along the machine direction 4.

In other words, the transfer devices 30 are translationally axially movable in relation to the transport devices 7 and 8; both with a first direction of movement 1 10, which is directed in the machine direction 4, and with a second movement direction 111, which is directed counter to the machine direction 4.

In this way, it can be effected that the weft threads 5 can be inserted into the working plane 18 at a transfer or insertion angle α F 90 and arranged opposite the warp thread 5, although the weft insertion device 3 is arranged at right angles to the transport devices 7 and 8 It is understood that the most different mechanisms for the translational and axial displaceability of the transfer devices 30 on the basis of various constructions in question. For example, the weft transport 2 has suitable rail carriage systems (not shown here) to move the transfer devices 30 in the sense of the present invention. In this respect, the respective transfer device 30 could be designed as a translationally displaceable carriage (not numbered separately).

The illustrations according to FIGS. 64 and 65 show how the weft threads 6 with the weft thread drivers 25 of the second weft insertion device 16 are moved in the direction of the second transport device 8 of the weft thread transport 2, wherein the transfer device 30 assigned to the second transport device 8 lies exactly below the second weft insertion device 16 is to ensure a clean weft transfer from the weft yarn 25 to the relevant transfer device 30.

In this respect, the transfer device 30 of the second transport device 8 is arranged congruently with the second weft insertion device 16 of the weft insertion apparatus 3.

In contrast to this, however, the transfer device 30 assigned to the first transport device 7 is already displaced in the first direction of movement 110, that is to say in the machine direction 4. As a result, the transfer device 30 of the first transport device 7 with respect to the first weft insertion device 15 of the weft insertion apparatus 3rd deflected so that the transfer device 30 and the first weft insertion device 15 are no longer aligned congruent to each other.

The illustrations according to FIGS. 66 and 67 show the time at which the weft yarn transfer from the weft yarn guides 25 of the second weft insertion device 16 to the transfer device 30 of the second transport device 8 is imminent. With regard to the transfer device 30 of the first transport device 7, a transfer of the weft threads has already taken place.

The representations according to FIGS. 68 and 69 show how the transfer device 30 of the first transport device 7 has now been moved in the second direction of movement 11 1, ie opposite to the machine direction 4 and thus again coincides with the first weft insertion device 15, by new weft threads 5 to be able to receive from the first weft insertion device 15.

The transfer device 30 of the second transport device 8 also moves with the weft thread 6 counter to the machine direction 4, namely also according to the second direction of movement 11, into a targeted transfer position (not additionally marked), so that the weft threads 5 can be transferred to the weft thread conveyor. port 2 with respect to the warp 6 can be aligned with a transfer or insertion angle a 90 °.

The further illustrations according to FIGS. 71 to 73 each show a cutout 120 of the upper insertion region 50 of the weft insertion apparatus 3, in which the weft insertion devices 15 and 16 of the weft insertion apparatus 3 are closely opposite each other at their upper deflection positions to be alternated by the weft threading device 40 (see FIG For example, Figure 1) to take over the weft 6.

The weft insertion apparatus 3 is further modified in this exemplary embodiment and comprises an alternatively configured clamping weft thread driver 25 which, in this exemplary embodiment, is still adjacent to the hook-shaped entrainment element 47 characterized by a hereby corresponding additional terminal element 121.

Due to the additional clamping element 121, the weft thread 6 is not simply taken hooked by the hook-shaped driver element 47, but in the interaction between the hook-shaped driver element 47 and additional clamping element 121, an ideally closed region (not separately numbered, but also 142) is created in which the weft thread 6 is securely enclosed, in particular during transport, so that the weft thread 6 can not unintentionally leave this closed area.

The closed area is designed according to the invention such that it has, at least temporarily, a border which the weft thread 6 can not unintentionally pass.

With regard to a variant embodiment, the weft thread 6 can move freely in this closed area.

Alternatively, however, it may also be advantageous if the weft thread 6 is additionally jammed on the hook-shaped carrier element 47 by means of the proposed clamping element 121, which significantly reduces the risk that the weft thread 6 inadvertently slides off the weft thread catcher 25, for example - By a sudden change in the weft tension.

As a result, an active driving device is created.

In this respect, the clamping weft thread driver 25 is characterized by a weft thread captive 122, this weft thread captive 122 essentially being embodied by the additional clamping element 121, which clamps the weft thread 6 against a corresponding catch element.

In this embodiment, the driver element 47 is hook-shaped, but it does not necessarily because of the additional terminal element 121. In this exemplary embodiment, furthermore, both the hook-shaped driver element 47 and the clamp element 121 are arranged on the rotating drive means 20, so that the hook-shaped driver element 47 and the clamp element 121 rotate together with the drive means 20 designed as a belt drive.

In this case, the additional clamping element 121 and the hook-shaped driver element 47 are fastened separately from one another on the belt drive.

In an alternative embodiment not shown here, however, the additional clamping element 121 can also be fastened to the hook-shaped driver element 47 so that the additional clamping element 121 is carried by the hook-shaped driver element 47. In any case, the hook-shaped driving element 47 and the additional clamping element 121 are arranged largely parallel to one another with regard to their longitudinal extent.

The additional clamping element 121 is designed to be longer than the hook-shaped driver element 47, so that it can more easily come into operative contact with an actuating device without this actuating device coming into contact with the hook-shaped driver element 47.

Such a suitable actuating device can be realized in a structurally simple manner, for example by means of an insertion aid 26 of one of the weft insertion devices 15 or 16 or the like. The additional clamping element 121 can be provided physically diverse, which in this exemplary embodiment consists of a thinner sheet metal. But also a wire or the like, for example also made of plastic or the like, can realize the additional clamping element 121.

In this embodiment, the thinner metal sheet has an inherent rigidity, which is sufficient to allow a clamping function of the weft thread 6.

Due to its inherent rigidity or inherent stress, the additional clamping element 121 is preferably designed as a prestressed resilient element, as is the case in this exemplary embodiment.

However, helical springs (not shown) or the like may also be used on the clamping weft driver 25 to bias the additional clamping element 121 accordingly.

The further illustrations according to FIGS. 71 to 73 now visualize the process of inserting the weft thread 6 into the alternative clamping weft thread driver 25 shown on the first weft insertion device 15, whereby, according to the illustration according to FIG. 71, the weft thread 6 additionally with the aid of an illustrated insertion aid 26 of the second weft insertion device 16 is brought to the clamping weft thread driver 25 of the first weft insertion device 15.

According to the illustration according to FIG. 72, the additional clamping element 121 is already lifted or spaced from the hook-shaped driver element 47 by the insertion aid 26 displaced further in the direction of the clamping weft thread driver 25, as a result of which the clamping weft thread driver 25 is opened, so that the Weft 6 reliable between the hook-shaped driver 47 and the additional terminal element 121 can be spent.

With a suitable embodiment of the clamping weft thread driver 25, the additional clamping element 121 can be opened solely by pressing in the weft thread 6 between the hook-shaped catch element 47 and the additional clamping element 121.

As shown in FIG. 73, the insertion aid 26 is again removed from the clamping weft thread driver 25 so that the clamping weft thread driver 25 is closed again (compare FIG. 71). Here, the additional clamp member 121 is due its springy properties zurückgeschnellt back in the direction of the hook-shaped driving element 47, so that the weft thread 6 between the hook-shaped Mitnehmer- member 47 and the additional clamping element 121 held or insofar temporally fixed or clamped in the clamping weft thread driver 25.

995 In other words, this means that the additional clamp member 121 has itself returned by its bias from the open state to the closed state.

In the area of the transport device 7 or 8 (cf., for example, FIG. 1), the weft thread 6 is removed again in a suitable manner from the clamping weft thread driver 25

1000 and transferred by means of the transfer device 30 to the respective transport device 7 bzw.8.

According to the representations according to FIGS, 74 to 77, alternative weft thread eyes 59 (cf., FIG. 20) are shown, which can be advantageously used on the device 1 in the context of the present weft threading device 40 (cf., for example, FIG

1005 NEN.

FIG. 74 essentially shows again the exemplary embodiment from FIG. 20, in which the weft thread eyes 59 are arranged translationally displaceable in the direction of movement 58 so that the weft threads 6 can be deflected correspondingly above the insertion area 50 should an insertion of the weft threads 6 occur ¬

1010 jumps, with a deflection of the weft eye 59 in the direction of movement 58 by means of a cam 60 along which a follower roller 61 of the weft eye 59 can roll.

In this embodiment, the weft eye 59 has a total of four eye holes 130 (numbered only as an example), these four eye holes 130 zuei¬ rigid

1015 are arranged one above the other.

In other words, that means that the four eye holes 130 on the weft eye 59 immutable to each other, so passive to each other, are arranged.

According to the representations of the further FIGS. 75 to 77, an alternative weft eye 59 (only partly shown, cf., FIGS. 20 or 74) is also shown with four eyes 1020 (only numbered by way of example), which, as in the exemplary embodiment can be moved from the figures 20 and 74 as a whole with the direction of movement 58, wherein the alternative weft eye 59, however, differs from each of the four eye holes 130 is associated with a displaceable eye hole element 131 (also numbered only as an example).

Such a displaceable eye-hole element 131 can be structurally simply implemented, for example, by a ball stone (not numbered here again) with a through-hole, with corresponding slide guides or slide tracks not being explicitly drawn in here again.

For example, the weft eye 59 such Kulissenfuhrungen or Kulis- 1030 senbahnen, in which the eyelet elements 131 are slidably mounted as sliding blocks.

This means that preferably each of the eye hole elements 131 and thus also each of the eye holes 130 can be moved independently of each other and individually on the weft eye 59.

In particular, each of the eye-hole elements 131 and therefore also each of the eye holes 130 can be displaced individually or individually in the direction of at least two axes 132 and 133 formed on the weft eye 59, cumulatively or alternatively by the movement of the weft eye 59.

By means of the eye hole elements 131 1040 or eye holes 130, which are individually movable on the weft thread eye 59, it can be determined individually for each weft insertion which weft threads 6 (cf., in particular, FIG. 1) are inserted, whereby any weft thread pattern in the context can be generated very simply. For this purpose, the individual eye-hole elements 131 are individually movably mounted on the weft thread eye 59 or the like along the axes 132 and / or 133.

1045 Insofar, the weft eye 59 of the exemplary embodiment shown in FIGS. 75 to 77 has an active eyelet adjustment 135 by means of which the individual eye-hole elements 131 on the weft eye 59 can be displaced individually.

At this point, it should be mentioned that the number of eye-hole elements 131 can also be selected as desired, depending on the number of weft threads 6 to be inserted

1050 can.

According to the illustration according to FIG. 75, the individual active eye-hole elements 131 are arranged at the same distance and aligned with one another on the active weft eye 59, as is the case with the passive weft eye 59 with its eye holes 130 from FIGS

1055 or 74 is the case.

For example, according to the representation of FIG. 75, all four eye-hole elements 131 with their weft eye 59 are each in a loading position (not separately numbered), in which weft thread 6, possibly coming from the weft threading device 40, can be successfully inserted into the weft thread eye 59.

1060, on the other hand, in the figure 76, another configuration is set on the weft eye 59 in which the eye hole member 131A disengaged along the first axis 132 is disengaged to a non-loading position (not separately numbered).

The situation is similar in the case of FIG. 77. There, another configuration is chosen on the weft eye 59, in which the object disengaged along the second axis 133

1065 eye hole element 131 A is also in a non-insertion position (not separately bezif fert) disengaged, while the remaining eye-hole elements 131 are still in their respective Einlegpositionen. According to the illustrations according to FIGS. 78 to 83, an exemplary embodiment with respect to an alternatively designed transfer device 30 with an additional 1070 weft scraper 140 is illustrated, whereby the area of the device 1 at the lower reversal ply 24 of the second transport device 8 of the weft insertion device 3 is shown by way of example is.

In this case, a discharge from the weft yarn 6 temporarily arranged on the weft yarn carrier 25 to the transfer device 30 is triggered by the additional weft yarn stripper 140, wherein the weft yarn 6 from the weft yarn yarn guide 25 is already affected by the contact between the weft yarn 6 and the weft wiper

140 dissolved or such a release is initiated.

The additional Schussfadenabstreifer 140 reduces the risk that the weft thread 6 critically clamped to the clamp 90. As a result, the transfer device 1080 can operate more reliably, since the weft thread 6 can be released more precisely from the transfer device 30 and transferred to the hook 92.

The additional weft scraper 140 in this case has a weft contact surface

141, against which the running into the terminal 90 and in their terminal chamber 142 running weft thread 6 and thereby is transferred to the hook 92.

In this case, FIGS. 78 and 79 essentially show the start of the weft transfer from the weft thread driver 25 of the weft insertion apparatus 3 to the terminal 90 of the transfer device 30, the terminal 90 being opened by the weft thread 6. For this purpose, the terminal 90 is disposed displaceably at least with a terminal component with respect to the weft contact surface 141.

1090 The weft thread 6 continues to run into the terminal space 142 of the clamp 90 until it encounters the weft scraper 140 of the transfer device 30 or the weft contact surface 141 located in the terminal space 142, as already described with reference to FIGS Case is, and the terminal 90 in this case by the weft 6 is open. As a result, the weft yarn 6 ge of the weft yarn 25

1095 finally releases and arrives at the hook 92.

According to the illustrations according to FIGS. 82 and 83, the weft thread 6 has already been introduced into the hook 92, so that, as a result, the weft thread 6 is finally removed from the weft thread catcher 25 and held on the transfer device 30.

FIGS. 84 and 85 also show an exemplary embodiment in which on the device

1100 tion 1 transfer devices 30 (numbered only as an example) can alternatively also be arranged with variably adjustable distances 145, 146 or 147 relative to one another, for example while the transport devices 7 or 8 (cf., for example, FIG. 1) of the device 1 with the transport hooks in FIG Machine direction 4 are moved, or cumulatively or alternatively before or after a movement in the machine direction. 4

According to the illustration according to FIG. 84, the individual transfer devices 30 are each still arranged at the same distance 145 from one another, while in FIG. 85 the information about the additional distances 146 and 147 indicates that the distances 146 and 147 denote the individual transfer devices 30 can also be variably arranged differently from each other, at least temporarily.

This makes it possible, as required, to achieve an active "concertina effect" with respect to the transfer devices 30.

For example, a variation of distances between transfer devices 30 in a time range after receiving the weft thread 6 in a transfer device 30 and before the transfer of the weft thread 6 to the transport devices 7 and

11 15 8 or the relevant transport hooks 9 take place, whereby in particular a weft thread density of the product to be produced can be easily varied.

In this case, it is conceivable that distances 146 and 147 between transfer devices 30 can be varied both uniformly and individually differently (unevenly), whereby, for example, goods with variable weft thread patterns are simple 1120 can be produced.

In this case, the transfer devices 30 can be placed individually, in groups or otherwise as one another with different distances 145, 146 or 147 relative to one another.

In this case, the transfer devices 30 can be moved relative to one another on the device 1 with virtually any desired variing devices 150 individually, in pairs, and / or in groups of 125 or so.

It should be explicitly pointed out at this point that features of the solutions described above or in the claims and / or figures can optionally also be combined in order to be able to implement or achieve the explained features, effects and advantages in a cumulative manner.

It is understood that the exemplary embodiments explained above are merely first embodiments of the invention. In this respect, the embodiment of the invention is not limited to these exemplary embodiments.

All features disclosed in the application documents are claimed as essential to the invention if they are new to the prior art individually or in combination with each other.
