Abstract

A loom simultaneously forms a plain weave ( 16 ) and a gauze weave ( 15 ) in a textile ( 9 ) in one weaving cycle. To form the plain weave ( 16 ), the adjacent warp threads ( 1 L ,2 L) that are used to form the upper shed and lower shed are alternately lifted from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position by the same drop wire/needle shank ( 4 ). To form the gauze weave ( 15 ), only the warp threads ( 2 D) that form the upper shed are raised by the drop wire/needle shank ( 4 ) from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position.

Description

Process for producing a fabric in plain weave and leno weaves and weaving machine for carrying out the process

The invention relates to a method for producing a fabric that has both plain weaves consisting of weft and warp threads as well as leno bindings consisting of weft and warp threads according to the features of the preamble of claim 1, and a weaving machine for carrying out the method according to the features of the preamble of claims 4 and 12.

The invention further relates to a shoulder lamella for a lamella and needle shaft of the weaving machine mentioned in claims 4 and 12.

From DE-PS 360 112 is a needle shaft device for the manufacture of

Known types of fabric with changing plain weave and leno weave.

The shafts are lifted in a controlled manner here, specifically when the drawer falls by a driver connected to the stilts. By changing the

Raising the shafts can be plain weave and by successively following

The same shaft can go up when it is laterally displaced

Lathe binding.

When the compartment is closed, an ordinary shaft is moved laterally to form the leno shed, so that the warp threads of this shaft over the needle tips and

Warp threads of the other shaft, which is a needle shaft, can be guided away.

Now the needle shaft, over whose needle tips the warp threads of the second

The shaft, that is, the ordinary shaft, has been lifted, this creates the leno pocket.

When the canvas compartment is formed, the lateral displacement of the warp threads is canceled; the shafts are raised alternately on a regular basis.

It is clear from the sequence described for the formation of a leno and linen compartment that a fabric with alternating linen and leno weaves can be produced, i.e. first a plain weave and then a leno weave can be formed in the fabric.

It is not disclosed how within a weaving cycle, i.e. from leaf stroke to

Leaf stop both a plain weave and a leno weave

Fabric can be produced. It is therefore not disclosed which means for simultaneously producing such

Ties could be provided in a fabric.

To make a fabric with leno weaves and plain weaves is out

DE-PS 646 462 discloses a device which has two needle combs one above the other in one plane.

The needle combs are controlled independently of one another, which makes it possible to change the weave while the weaving machine is running so that plain weave can also be realized after one or more leno weaves.

However, the document does not disclose how canvas and leno weaves can be formed at the same time in a fabric and what means for their

Training.

A weaving machine for producing a fabric consisting of upright, leno and weft threads is known from DE 101 28538 A1.

This document also does not disclose how plain weave or leno weaves can be realized at the same time in fabric production.

It is an object of the invention to realize plain weave and lathe weaves within a fabric to be produced, with the saving of costly subject-forming means within a weaving cycle.

The task is accomplished by a method and a weaving machine

Process implementation solved.

According to the method according to the invention, plain weaves and leno weaves can be formed simultaneously in a weave to be produced.

In an embodiment of the invention, it is provided to form the

Plain weaves alternately or alternately from one position of the same lamella and needle shaft from the position of the lower compartment into the one serving for forming a lower compartment and an upper compartment

To lift the position of the upper compartment and vice versa to return to the position of the lower compartment.

Simultaneously with the formation of the canvas pocket, the formation of the leno pocket is effected with the same lamella and needle shaft, in such a way that only those which serve to form the leno top pocket serve in a manner known per se

Warp threads are raised. When the canvas and leno compartments are essentially raised, as is known per se, at least one weft thread is inserted into the compartment. The inserted weft thread is then struck on the fabric edge. When the at least one weft thread is struck, the second lamella and needle shaft, which lifts the warp threads to form the upper compartment, goes into the lower compartment position via the compartment closure. At the same time, the first lamella and needle shaft is displaced transversely to the course of the warp threads, so that the warp threads guided in the first lamella and needle shaft are laterally offset or offset with respect to the warp threads guided in the second lamella and needle shaft. When the warp threads are laterally offset, the warp threads previously realized in the canvas upper compartment now form the canvas lower compartment, while the warp threads of the original canvas lower compartment are used to form a new canvas upper compartment and at the same time the warp threads originally used to form the leno upper compartment be used again to form a lathe upper compartment.

With this mode of operation of the first and second lamella and needle shafts disclosed above, a plain weave and a leno weave are realized simultaneously within one weaving cycle.

In the case of light medical dressing material, for example, which is woven as a tape in plain weave, separate leno devices can be dispensed with to form firm fabric edges, because according to the method according to the invention, plain weave is carried out together with at least one leno weave on the fabric edges of the tape with only two lamella and needle shafts can.

To carry out the method according to the invention, a weaving machine is provided which has means for forming a shed, means for inserting weft threads into the formed shed and the means for striking the weft thread inserted into the shed against the stop edge of the fabric to be produced.

As is known, the means for forming the shed consist of a first lamella and needle shaft, which is connected to a drive that allows a reciprocating movement of the first lamella and needle shaft that oscillates transversely to the warp threads and thus oscillates transversely to the weaving plane.

Furthermore, the means for forming the shed consist of a second lamella and needle shaft adjacent to the first lamella and needle shaft, which is connected to a suitable means which engages in a rotationally fixed manner on a shaft which is remote from the loom shaft of the weaving machine, and the drive of this shaft is derived from the loom shaft.

For the simultaneous production of plain weave and leno bindings in a fabric, it is now provided according to the invention that on a section of the working width of the first and second lamella and needle shafts determined for the formation of leno bindings, between two in each case in the upper and lower shaft collar of the first and second lamellae - and needle shaft locked rod lamellae each a needle lamella is connected with thread guide eyes directed away from each other, and that on another section intended for the formation of plain weaves the working width of the first and second lamella and needle shaft, in the first lamella and needle shaft, that of the sley of the Weaving machine is closest, a plurality of spaced-apart bar lamellae is arranged next to one another, which bar lamella in the second lamella and needle shaft is known as either each even-numbered or each odd-numbered bar lamella of the first lamella and needle shaft e shoulder lamella is assigned to a single or double-sided shoulder. In a further embodiment of the invention, the shoulder slats consist of an elongated, flat, preferably metallic body, which according to the invention has a laterally outstanding first and second shoulder at one point of its longitudinal extent, on which alternately a warp thread from the lower compartment of the warp chain to form a canvas pocket Upper compartment and vice versa from the position of the upper compartment to the position of the lower compartment. The shoulder can have a special design; the shoulder can have a trough-like depression in order to be able to safely lift and lower the warp thread; the surface of the shoulder carrying the warp thread can be level and aligned at an angle α <90 ° to the longitudinal extent (longitudinal axis of the shoulder lamella).

The outstanding shoulders can be connected to the elongated body by an inseparable connection and enclose an angle β <180 °. However, each shoulder lamella can also consist of a first, elongated, flat body with a shoulder bent out from the flat side of the body and a second body formed in mirror image of the first body. Both bodies are then joined in the upper and lower shaft collar of the lamella and needle shaft in such a way that these bodies form the shoulder lamella with the shoulders facing away from one another. In a further embodiment of the invention, each of the even-numbered or each of the odd-numbered bar lamellas of the first lamella and needle shaft, that is to say of the lamella and needle shaft moving transversely, ie horizontally to the weaving plane, can also have a shoulder lamella to form the canvas-binding fabric, which has at least one shoulder on one side for holding down the linen-bound warp threads not involved in the formation of the upper compartment. The shoulder of the shoulder slats holding down the canvas-binding warp threads is formed approximately in the plane of the thread guide eyelet of the needle slats of the first slat and needle shaft.

In a preferred embodiment, the shoulder is designed in the manner of a trough-shaped recess which is open at the bottom. In contrast, the shoulder of the shoulder lamellae of the second lamella and needle shaft forms a trough-shaped recess that is open at the top.

In a further embodiment of the invention, the shoulder lamella is designed as an elongated, flat, preferably metallic body which, on one side in the area of its longitudinal extent, has a shoulder pointing counter to the feed direction of the warp.

Instead of the shoulder, a trough-shaped recess can be provided in the corresponding rod lamella in the relevant area of its longitudinal extent. The trough-shaped recess runs out into a hook shape. The recess can also be of different geometrical shapes; it is crucial that the relevant warp thread can be grasped through the respective recess in the bar lamella of the first lamella and needle shaft and is held down in its predetermined position when the shed is formed.

With the solutions according to the invention it is possible for the first time to produce fabrics in plain weave and leno weaves on weaving machines without an additional shedding machine, including shafts with heddles and beams, within a weaving cycle.

With the omission of additional shafts, the front compartment can be made shorter in such weaving machines. The warp threads of the lower compartment are in relative rest, so that, for example on air jet weaving machines, the lower compartment is not displaced far below the lower nose of the weft insertion channel extending in the reed. With the solution according to the invention, there is also advantageously no need for a hold-down device for the warp threads in the area of the rear compartment; Warp thread stapling in the area of the specialist facilities is completely avoided and fabrics with faulty plain weave are excluded.

Further advantageous effects of the invention emerge from the patent claims and from the following exemplary embodiments.

The invention is explained in more detail below using an exemplary embodiment.

FIG. 14 shows the schematic representation according to FIG. Figure 13, wherein the first lamella and needle shaft assumes the right reversal position transverse to the weaving plane.

The weaving machine shown schematically in FIG. 1 executes a movement sequence, according to which the warp threads 1 and 1 _{D of} a first warp thread family are located in the lower compartment and are caused to move horizontally transversely to the inflow of the first and second warp thread families, while the warp threads 2 _{D of} the second warp thread family only be moved vertically into the upper and lower compartment. Accordingly, the lamella and needle shaft 3 only moves transversely to the warp thread coulters, while the lamella and needle shaft 4 alternately executes a substantially vertical up and down movement with the warp threads 1 _L and 2.

The insertion of a weft thread into the entry channel of a reed 5 mounted on a sley 6 takes place in the time interval in which a shed 7 is formed, that is, the lamella and needle shaft 4 is in its position shown in FIG. 1. The stop of the weft thread, not shown here, at the binding point 8 of the

Fabric 9 takes place, for example, at a point in time at which the warp threads 1 _{D change} their position transversely to the feed of the warp thread groups or in the horizontal direction.

With such a sequence of movements, the fabric is produced in leno weave 15, see also FIGS. 9 and 10.

The rollers mentioned are in a machine frame shown in sections

23 rotatably mounted, which also carries the fabric table 17.

The drives assigned to the rollers are known per se and are not shown further.

In the area between the point 24a of the match tree 24 and the lamella and needle shafts 3, 4, the warp threads 1, 1 D and 2 _L , 2 _{D run} through one

Warp thread monitor 25, whose 1 _L , 1 D! 2 _L , 2 _D spreading slats 26 as well as the warp threads 1 _L , V. 2 _L , 2 _D are easily accessible from above in the event of a warp thread breakage.

The sley 6 with the reed 5 is on supports 27 with one in the

Machine frame 23 rotatably mounted, an oscillating rotary motion executing shaft, the so-called shutter shaft 28, firmly connected to the

The axis of rotation is a reciprocating one that serves to weft stop

Movement.

The drive of the shaft of the shutter is generally known, so that further explanations are not necessary. The basic structure of the lamella and needle shafts 3, 4 can be seen from FIGS. 2 and 3.

The lamella and needle shafts 3, 4 have a lower collar 29 and an upper collar 30. Both shaft bundles are enclosed by a frame, the so-called shaft frame 31.

Both lamella and needle shafts 3, 4 have a multiplicity of spaced-apart rod lamellae 10, the respective ends of which are anchored in the upper and lower shaft collar 30, 29.

In order to be able to simultaneously form a plain weave 16 and a leno weave 15 in a fabric 9 in accordance with the method according to the invention, as shown in FIGS. 9 and 10, a first one is provided according to the invention

Longitudinal section of the weaving width of the lamella and needle shaft 4 according to the invention is a so-called between two adjacent lamellae 10

Shoulder lamella 12 is provided and so-called needle lamella 11 with a thread guiding eyelet 11a are provided between the bar lamellae 10 on a second predetermined length section of the same lamella and needle shaft 4, best seen in FIGS. 3 and 4.

Furthermore, on a second one identical to the first length section

Longitudinal section of the weaving width of the lamella and needle shaft 3, between each two bar lamellae 10, a needle lamella 11 with a thread guide eyelet 11a is arranged.

The thread guide eyelets 11a of the needle blades 11 of both blade and needle shafts

3, 4 are directed away from each other.

A shoulder lamella 12 according to the invention is shown in FIG. 5.

The shoulder lamella 12 here consists of a first single-bar lamella 13 with a so-called half-shoulder 13a and a second single-bar lamella 14 with one

Half shoulder 14a.

Both half-shoulders 13a, 14a have a trough-shaped recess as a temporary warp thread carrier.

In FIGS. 9 and 10, the shoulders that temporarily support a warp thread 1 _L , 2 _{L are} flat. In FIG. 7, the shoulders are oriented at an angle β 90 90 ° to the longitudinal extension of the slats 13, 14 in such a way that the relevant warp thread 1L, 2 _L can be safely lifted out to form a shed and can slide safely off the shoulder in the lower shed. According to the sectional view AA in FIG. 6, both shoulders 13a, 14a can enclose an angle α <180 ° and have a leg length L in such a way that, on the one hand, there is no contact with the neighboring rod slats 10 and, on the other hand, that there is a sufficiently large lateral air gap between the shoulders 13a, 14a and the adjacent bar lamella 10 for a mutual picking up and taking off of warp threads 1 _L , 2 _{L is} present.

FIG. 8 shows the side view of a shoulder lamella 12 with the trough-shaped recess in the shoulder 13a, 14a for a warp thread 1 or 2.

The method of making a fabric with the simultaneous formation of

Plain weaves and leno bindings will be explained with reference to FIGS. 9 and 10.

The lamella and needle shafts 3, 4 shown schematically in FIG. 9 have, as stated above, rod lamellae 10 and needle lamellae 11 with a thread guide eyelet

11a.

Only the lamella and needle shaft 4 additionally has shoulder lamellae 12.

The lamella and needle shaft 3 leads transversely to the inlet of the warp threads 1 _L , 1 _D ; 2, 2 _D an oscillating reciprocating motion. The back and forth

Movement is indicated by the directional arrow 32.

The lamella and needle shaft 4 executes a substantially vertically oscillating up and down movement, as indicated by the directional arrow 33.

In the gaps between the shoulder slats 12 and the bar slats 10 des

Lamella and needle shaft 4 on the one hand and in the gaps between the

Rod slats of the slat and needle shaft 3, on the other hand, the warp threads 1 _L , 2 _{L are} drawn in to form a plain weave 16. In each case a warp thread 1 _D is in the thread guide eyelet 11a of each needle plate 11 of the plate and needle shaft

4 and in each case a warp thread 2 _D is drawn into the thread guide eyelet 11a of each needle lamella 11 of the lamella and needle shaft 3 in order to achieve a leno binding.

When lowering the shaft 4 in the lower compartment, according to. Direction of the downward-pointing double arrow 33, this corresponds to the position of the warp threads 1 | _, 1 _D in FIG. 9, and with simultaneous transverse movement of the lamella and needle shaft 3 to the right in the direction of the double arrow 32, the corresponding warp threads 2 are applied to the by means of the lamellae 10 left shoulder 14a or right shoulder 13a of the shoulder lamellae 12. Then the lamella and needle shaft 4 moves from the position of the Lower shed in the position of the upper shed, whereby the warp threads 1 and 2 form a plain weave shed.

In the same way, all the warp threads 2 _{D of} the lamella and needle shaft 4 guided through the thread guide eyes 11 a are moved from the position of the lower shed to the position of the upper shed, whereby the warp threads 1 _D and 2 _{D form} a leno shed. Subsequently, a weft thread 34 is inserted into the formed canvas and leno pocket 7, through the reed 7 according to FIG. Figure 1 struck at the binding point 8 and tied by changing the lamella and needle shaft 4 from the upper compartment to the lower compartment by means of the warp threads 2 _L and 2 _D.

According to FIG. 10, while the slat and needle shaft is in the sub-compartment position, the linen-binding warp threads 1 _{L are placed} on the shoulder 13a or 14a of the respective shoulder slats 12 by a new transverse movement of the slat and needle shaft 3 in order to again have a canvas pocket and a To be able to form a lathe operator.

In a further embodiment of the invention, there are means for producing a fabric with plain weave and leno weaves in accordance with. FIG. 11 from a weaving chain supplied by a warp beam, not shown here, consisting of plain-weave warp threads 1 _L and 2 _L and of twine-warp warp threads 1 _D and 2 _D. The warp threads mentioned are, starting from the binding point 8 of the fabric 9, one after the other into a weaving reel 5 which is pivotally driven about the central axis 28a of the weaving shaft 28, into a first lamella and needle shank 3 and in which are driven so as to be movable back and forth transversely to the weaving plane 35 a second lamella and needle shaft 4 is pivotally driven about the center axis 36a of a swivel arm shaft 36 which is arranged at a distance from the reed shaft.

As already disclosed above, the first lamella and needle shaft 3 has a multiplicity of rod lamellae 10 and a needle lamella 11 with a thread guide eyelet 11a at provided locations between each two rod lamellae 10, see also FIGS. 9 and 10.

Between the bar slats 10 of the first slat and needle shaft 3, the warp threads 1 _L and 2 are alternately received to form a plain weave fabric 9, while in each thread guide eyelet 11 a of the needle slats 11 a warp thread 1 _D for forming a leno fabric 9 or for forming a leno edge as Completion of a canvas section of tissue is performed. Accordingly, the second lamella and needle shaft 4 also has a large number of bar lamellae 10, a so-called shoulder lamella 12 having a shoulder 13a, 14a for alternately receiving a warp thread 1 or 2 being positioned between the two bar lamellas 10 in each case. Also in the lamella and needle shaft 4, a needle lamella 11 with thread guide eyelet 11a is provided at provided locations between two rod lamellas 10, which, together with the needle lamella 11 with thread guide eyelet 11a of the first lamella and needle shaft 3, realize the leno fabric 9 or individual leno bindings.

In a further embodiment of the invention, for the purpose of avoiding defective plain-weave fabric 9, the cause of which is to be found in clinging warp threads in the area of the rear pocket 7a, a shoulder lamella is alternately provided between each even-numbered or each odd-numbered bar lamella 10 of the first lamella and needle shaft 3 12 arranged, or the relevant bar lamella 10 is designed as a shoulder lamella 12, specifically with a trough-like, vertically downward opening 13a, which runs out to form a hook, in order to alternate the warp threads 1 | _ or 2, if these are not during the weaving shed formation the second lamella and needle shaft 4 are moved into the upper compartment to hold down, see also 11 to 14.

The means for forming a shed 7 formed from the upper and lower shed here consist of the second lamella and needle shaft 4 with those already mentioned

Rod, shoulder and needle slats.

The lower collar 4a of the lamella and needle shaft 4 is at the free end of at least one swivel arm which rotatably engages on the swivel arm shaft 36

37 connected.

The swivel arm shaft 36 has a connecting strap 38

Shutter shaft 28 equipped with a connecting strap 39. Both

Connecting straps 38, 39 are coupled via a rod 40.

In FIG. 12, the warp threads 2 _L and 2 _D are guided through the second lamella and needle shaft 4 into the lower shed position, that is to say positioned below the weaving plane 35. During this position, the first lamella and needle shaft 3, corresponding to FIGS. 13 and 14, is moved transversely to the weaving plane 35 according to double arrow 32 from its outer right position, see also FIG. 14, into the outer left position, see via a drive, not shown here also Figure 13, moved. Accordingly, the first lamella and needle shaft 3 causes a new one to be formed canvas-weaving shed, the warp threads 2 _L guided into the lower shed are led out of the recess 13a of the shoulder slats 12 of the second slat and needle shaft 4 and into the recess 13a of the shoulder slats 12 of the first slat and needle shaft 3, while those in the recesses 13a of the Shoulder slats 12 held warp threads 1ι_ out of these and into the recess 13a of the shoulder slats 12 of the second Lamellβn- and needle shaft 4 are guided.

Due to the fact that the relevant slats of the first slat and needle shaft 3 are designed as shoulder slats 12 and the relevant warp thread 1 _L or 2 is held down during the shed formation, weaving errors in the canvas fabric are excluded.
