Device for producing short warps, especially for fabric patterns in color weaving

The invention relates to a device for producing short warps, in particular for fabric patterns in colored weaving.

In a known device of this type, the threads of different colors are wound up one after the other and next to each other, after which the resulting group of threads is separated in the transverse direction. Here, the thread guide device can be moved along the circumferential contour of the winding device, with the carrier of the winding device being fixed. The winding surface is transverse to the direction of movement of the thread guide device.

The thread guide is designed as a catch hook to move the thread around the deflection rollers. The thread guide is attached to a

The object of the invention is to make the described device, in particular for the production of short chains, more efficient in a simple manner. The invention is characterized by the fact that more than ^one

Thread guides or catch hooks are attached to the circulating belt. The circulating belt is preferably provided with two thread guides or catch hooks, the thread guides being arranged at a distance of ²⁵ from each other, half the length of the belt.

The device is achieved with little expenditure on the additional parts.

In special cases it is possible to provide more than two thread guides in one and the same conveyor belt. The distance between the thread guides is evenly distributed over the length of the conveyor belt.

The invention is explained below using an embodiment shown in the drawing.

Fig. 1 shows an embodiment of the device for producing short chains according to the invention in elevation and diagram.

Fig. 2 shows the device of Fig. 1 with the feeding of the thread to the circulating belt in front view and on a larger scale.

Fig. 4-5 show a control option in the diagram

for switching from a single thread guide operation to a two thread guide operation and vice versa.

The device 1 for producing short chains and the like of a standing design has frame parts 2 and 3 and a

deflection elements 6 and 7, preferably as deflection rollers, are rotatably mounted, on which conveyor belts 8 are guided and moved in the longitudinal direction to receive the thread to be wound up. The device 10 for feeding the thread to be wrapped around the deflection rollers 6 and 7 has an endless circulating belt 11 which is guided around the disks 12. To form

-j 5 crosshairs in the thread group guided around the deflection rollers 6 and 7 are the part shafts 14 and 15. 16 designates a cover hood which serves as a guide element for the thread to be folded over.

To change the threads of different colors, thread guides fixed to the circulating belt 11 are used, e.g. the thread guides 18 and 19, which are preferably designed as catch hooks. The thread guides 18 and 19 are suitably arranged at a distance of half the length of the circulating belt. This significantly shortens the idle path compared to the arrangement of only one thread guide, and with two thread guides on the circulating belt it is reduced to half.

The catch hooks 18, 19 work together with swivel arms 20. There should be as many swivel arms as different colored threads are to be processed simultaneously in a chain. Each color is assigned a

&bull;&igr; · · < · ··<■ ■&bull;&bull;&bull;(&bull;I ·· H « · ··

The free end of the swivel arms 20 is provided with a hook 21 into which the thread can be installed. The swivel arms 20 can be controlled individually and independently of one another by rotating magnets 22. The spools 25 with threads of different colors for producing, for example, short warps for colored weaving are located on the spool stand 24. The threads 28 run from the spools 25 through movable eyelets 26 to the hooks 21 of the swivel arms 20. The threads are hooked into these hooks 21 and then run on to be attached to the frame 3.

In the rest position, the swivel arms 20 assume position I shown in Figure 3, i.e. a position behind the deflection disk 12. The threads 28 run at a large distance from the circulating belt 11 or the thread guide 18 or 19 to the hooks 21 of the swivel arms 20, so that when the thread guide or catch hook 18 or 19 rotates, the threads 28 running along the line 29 are not caught by the catch hook 21.

However, if a thread from the spools 25 is to be laid around the deflection rollers 6, 7, the swivel arm 20 associated with the spool 25 is swiveled by the corresponding rotary magnet 22 into position II shown in Fig. 3, whereby the thread 28 now takes the path 30, since the end of the thread 28 is firmly connected to the band 8 of the deflection roller. The thread path 30 is brought in front of the catch hook 18 or 19 in such a way that it can pick up the thread when it rotates by means of the band 11 and lay it around the deflection rollers 7. The other threads, on the other hand, remain in the path 29, in which the threads are caught by the catch hook 18 or 19.
