It is a very durable material Twist thread, z. JB. made of polyamide or similar Kims ts tof f, which is stretched over the edge of the fabric.

The ends 7a_, 8 <α, 9a_ of the weft cases are wrapped around the twisting thread I1 in the direction of the inside of the fabric towards one another, and each thread is tied through the loops of two, also preferably very resistant, binding threads 13 »1 ^ ι ^ζ · ^π · Po lyaniLdf äden or the like., Constricted.

In this embodiment, each of the two binding threads runs alternately over the bottom and top of the successive weft threads.

The folded weft threads are tightly constricted between the twist thread 11 and the first warp thread I by the loops formed by the two binding threads 13 and \ h.

This creates a very durable bar that prevents the warp threads from sliding sideways; they are namely by the two binding threads

however, for the or ti Lt; (ni) nachfo l.iond.'U weft threads that are not looped:>'"» Lten, like 20, below the level of the following wefts, the twisting thread II and the two binding threads 13 are at the same time , 1H kept lowered, then only the IJrelif udfii H aiigehobori for the ri-fcen weft thread (1?) To be looped,

In Fig. 5 is a different from f iihrim ..r ^ possible 1 i ohki>; ί the method for forming the bar according to the invention shown; it orders that in the manner previously described along the fabric edge, iwe l Ifvisf.en are achieved, which are designated in their Ge stunt no it with 22 and 21 , then between the two strips, /. . ß, the weft threads have been cut by means of a knife for 2 hours. The bar 23 remains on the edge of the fabric, while -lie bar 2'i forms a waste in the form of a cord.

It goes without saying that these strips can be manufactured in any of the shapes listed above s ί nd.

The device for forming a bar on a gripper chair according to FIGS. 6 to 10 consists of an arrangement with two identical vertical, in this example cylindrical rods 31 »32 for fastening to the leaves of a crockery, which are driven in opposite configurations, such as z. B. those used for canvas painting. For this purpose, the ends of these two rods carry slotted heads 33 t 3 ^ or 3.51 3i> »which can be mounted on the corresponding harness sheets 37» 33 and 39 , ~ IO , which serve as supports for the strands, such as. B. kj, kh serve. Every head, so z. B. 3b, has an adjusting screw k5 , by means of which it can be determined on the corresponding crockery sheet.

009829/0232

On the two rods 3I and 32 two consisting of hollow blocks ha, k9 elements are freely displaceable, which under the action of an elastic means, for. B. the spring 51 'move away from each other; the spring 51 "consists of an arched steel wire which lies in a plane extending parallel to the plane of the two rods 31» 32 and whose curved ends engage in openings 52, 53 which are let into the two blocks k & and 'φ.

Cotter pins 5 '·· »55 going in into the curved ends of this spring Recessed holes engage, prevent these ends from sliding out of their respective blocks.

The upper sliding block kS carries a leno thread guide. This consists of an eyelet 53 which is let into the lower end of a needle 59. This needle 59 is vertically connected to the block with its approach by means of two screws b1, 62. The rotary thread 11 also runs in an upper guide which consists of a catch 63 which is let into the upper part of the attachment for fastening the needle on the block.

As can be seen from the drawing, in this example the upper slide block k8 is equipped with a second needle 59a, because the device shown is a double device for producing two strips lying next to one another, e.g. for the production of a fabric from several strips when a double strip with a cord is to be made on the edge of a fabric, which, as shown in FIG. 9 of the main patent, is separated.

In the following, only one half of the device for forming finer bar is described, the mechanism for forming the second bar with respect to the? through the axes of the two rods '31, "} 2 laid plane is symmetrical to the first mechanism and sr-im? organs are designed according to those of the first and are denoted by the same reference numerals with the addition of the TndfX" .a ".

The lower sliding block HS carries a double thread guide 65 with two eyelets 66, ό7> in each of which the two binding threads 13, 1 * 4 run; the thread guide 65 is fixedly connected to an axle 68, which is free in the upper part of the block ¹ I ^'1 about a horizontal geometric axis swingably, which runs parallel to the plane of the axes of the two rods 31, 32nd The pivot axis 68 of the thread guide 65 lies in the vertical longitudinal plane which runs through the thread guide 58, ie through the needle $ 9 for guiding the rotary thread.

The yarn guide 65 may alternately two in the illustrated example (substantially, by 5 '*) taking inclined positions, then each of the two binding yarns 13, 1 k alternately to the left and the vertical longitudinal plane to the right is represented by the eyelet 58 for guiding the Twist 11 goes ♦

The regularly recurring pivoting movement of the thread guide 65 is ensured by a drive with a crank pin 71 which is attached to the end of the axis 6 , which is opposite the one carrying the thread guide, a connecting rod 2, one of which is curved at the end of the crank pin 71 hinged and the other end of which is applied to one on one end of a dump truck 75

Axis 74 is rolled up. This tipper consists of one small part in the form of an obtuse, wide open angle, the two legs of which with a large gap of the two vertical rods 31, 32 via two corresponding ones Openings 76, 77 are traversed. The dump truck 75 lies between the lower end of the lower slide block 49 and the lower heads of the two slide bars 31 »32.

When one of the two vertical rods, e.g. B. the rod 31 assumes its upper position, as shown in Fig. 10, causes its lower head 34 the corresponding arm of the tipper 75 to rest on the lower end of the lower sliding block 49, so that the connecting rod 72 assumes its upper position with respect to the block 49 and the crank pin 71 and the thread guide 65 assume the corresponding inclined positions shown in FIGS. If, on the other hand, the other rod 32 assumes its upper position (FIGS. 7 and 3), then this time its head 36 forces the corresponding arm of the tipper 75 to rest against the lower side of the block 49, so that the connecting rod 72 assumes its lower position and the The crank pin 71 and the thread guide 65 each assume right-angled positions with respect to the preceding, ie with respect to the vertical longitudinal plane which runs through the needle 59 for guiding the rotary thread 11 (symmetrical positions).

In Fig. 6, two continuous warp threads 77, 78 are shown, each in the corresponding strands 43, 44 are drawn in, three weft threads 7> 8, 9 »their ends have already turned over in the bar, a weft thread 19, the end of which has not yet turned over, and finally a weft thread 17 which is still in the shed; the crest is shown partially at 81.

009829/0232

The operation of the device is as follows:

In the position shown in FIGS. 6, 9 and 10, the harness sheet 37 and consequently the warp thread 77 and the rod 31 are in the upper position, while the harness sheet 39 and consequently the warp thread 78 and the slide bar 32 are in the lower position.

The two slide blocks are brought closer to each other by the upper head 35 of the rod 32 and the lower head of the rod 31 against the force of the spring 51. The needle 59 guiding the rotary thread 11 is lowered between the two binding threads 13 and 14, the thread 13 being on the left (FIG. 6) of this needle and the thread 14 on the right. The weft thread 17 t, which has just been introduced into the weave and which is located below the warp thread on the one hand, is simultaneously below the two binding threads 13 and on the other hand above the warp thread 78 and at the same time above the twist thread 11.

If, when changing the position of the strands, the rod 31 lowers at the same time as the rod 32 is raised, there comes a moment when the two rods are at the same height, so that the head 36 of the rod 32 slightly lifts the tipper 75 while the Head Jh of rod 31 allows the corresponding arm of this dumper to drop slightly. This pivoting movement of the tipper 75 occurs at the moment when the two sliding. blocks k8 _f k9 are furthest away from each other and the eyelet 58 for guiding the rotating thread 11 is located somewhat below the thread guide 65 , in which the two binding threads 13, \ k engage. The two binding threads now cross under the twisting thread, so that the binding thread I3 is now to the right of the vertical plane of the needle 59

0098 29/02 3 2

for guiding the twisting thread, but the binding thread Ik is to the left of this plane.

The movement of the strands stops, i.e. h, the rod 32 is raised further while the rod 31 continues to descend, and the slide blocks 48, 49 now begin to approach each other so that the needle 59 moves the twisting thread between the lowers both interlaced binding threads. Is the pole 31 in its lowest position and the rod 32 in its highest (Figs. 7 and 8), then the rotary thread 11 takes off a new subscript, which essentially, the plane of the lower shed, while the two binding threads their essentially corresponding to the plane of the upper shed Assume superscript.

In summary, it can be said: every time a strand changes from its upper to its lower position, it goes corresponding strand from its low to high position and the two sliding blocks 48, 49 lead during this Time out a moving away movement, followed by an approaching movement, so that the twisting thread begins to rise again, while the two binding threads fall off with a weft thread constricting; then cut the two binding threads below the twisting thread and the latter rises again between the two crossed over Tying threads on, so that the shed is formed again to take up a new weft thread.

According to FIG. 6, the two binding threads pass through always achieved above the weft threads, the passage of the twist thread always below the weft threads and the cutting of the two binding threads alternately on one side and the other underneath of the twisting thread.

009829/0232

In the same way as the weft thread ends are released during weaving, they are immediately released by the corresponding Fold over the loop of the two binding threads towards the inside of the fabric.

It will be noted that in the representations according to Fig. 1 to 5 of the Drehfaderi always in the upper compartment and the There are binding threads in the lower shed, while in this embodiment the twisting thread in the lower shed and the binding threads lie in the upper shed, so that the weft thread ends fold downwards, while they are upwards in FIGS. 1 to 5 were handled; However, this does not change the basic idea behind the formation of the bar.

Of course, the invention is not limited to the above listed embodiments limited, but numerous modifications are possible without departing from the spirit of the invention.

For example, strips on parts with several Fabric widths are formed in the same way.
