The invention relates to a method and a device for the production of short chains, especially for fabric samples in colored weaving.

According to the main patent, threads of different colors are consecutively single-layered wound next to each other, and it is the so obtained as an endless thread sheet band in Split crosswise, forming two crosshairs.

The distance between the deflection elements, i.e. H. «> The guide rollers, corresponds to half the chain length. If the distance is made variable by the fact that the outer deflecting element, i. H. the outer deflection roller, between the frame parts of the machine towards the other deflection roller is displaceable, there is probably the possibility of changing the length of the thread sheet, but only up to a maximum chain length for which the machine is intended. But there is no change the chain length according to the conditions given by the overall dimensions of the machine.

The invention is intended to make it possible to use different chain lengths on one and the same machine. It has been found that different on the same machine long chains can be produced without changing the center distance of the deflection rollers. This is done in that the crosshairs after a predeterminable, arbitrary number of 3 » Thread circulations are formed and that the thread forming the crosshair is separated by cutting will. If you want a longer chain, the length of which is greater than a wrap around the two Deflection rollers, so the thread is guided a multiple of one turn around the two deflection rollers, but without the crosshair being formed in the meantime. So you switch during the multiple handling of the thread around the two deflection rollers the activity of the crosshair direction the end. The rotatably driven to form the crosshairs partial shafts are here only after the first and last turn around the pulleys so that the crosshair is only at the beginning and the end of the chain which is guided several times around the guide rollers. If with the so educated Fadenschar a separation is made only with that thread in which the crosshair is formed is, you get a chain with a multiple length of the simple chain thread circumference, as the case may be, with how many turns the thread is guided around the deflection rollers without a crosshair being formed.

In this way it is achieved that the overall length or the overall height of the machine, in particular the Distance of the deflection rollers, can remain unchanged and, one on a maximum value of the chain length nicEx is restricted. You can achieve a chain length with the same distance between the deflection rollers, which corresponds to any multiple of the simple handling of the thread around the guide rollers. Here one is only informed by the width given to the machine, i. H. the length of the guide rollers, limited. This allows you to meet all demands on chain lengths for the production of Do justice to fabric patterns. The distance between the deflection rollers can be proportionate from the outset Keep it small, since a multiple or multiple of the simple chain length is produced in each case can. As a result, the overall length or overall height of the machine can be kept relatively small. You save space and material.

The invention is explained below with reference to the embodiment shown in the drawing.

3 4 cut through the machine of FIG. 1 and is mounted displaceably in the longitudinal direction of the partial shaft. cut schematic. This tie rod has a to the path of the thread The sample chain winding machine of the standing type guide 58 directed hook 72 on. It is under has side frames 1 and 2 and the lower transverse effect of a return spring 73 and a tension cross member 4. In the frame parts 1 and 2, the 5 magnets 74, which are in the partial shaft, for. B. 26 b, is arranged on the head deflection elements 5 and 6 in the form of deflection ends of the same. The hook 72 of the rollers rotatably mounted, on which the longitudinal tie rod protrudes through a slot 75 of the partial shaft, the roller belts 9 as a support for the wind-up - the head end of the partial shaft on the back of the thread are guided and movable. Is provided with a bevel 76 as a transport.
Device 12 for feeding the thread for the i ° The actuation of the pull magnet is dependent on the turning around the deflecting rollers 5 and 6, an end of a counting device is provided for the revolutions of the loose belt 13, which controls the thread guide around the discs 14. For this purpose a photocell (cannot run around it. To form the crosshairs of the posed) photocell can be used. 5 the revolutions of the circulating belt 13 or the thread are rotatably mounted. The partial waves are determined on the free leader 58 and counted. The UmEnde with an angled approach provided as racing counter operates with a switch (not dardieser α at 26 and 27a of Figs. 2 and 3 made visible) together by the tie rods 71 is connected. The clamping sleeve 28 is in the flange sleeve 50 with the hooks 72 alternately in the upper and by means of roller bearings 51, z. B. needle bearing, rotatably mounted. ² ° lower partial waves are pushed forward. The thread A rotary thread guide 58 designed as a catch hook on the magnet 52, which is attached to the traverse 53 and slotted head end 77, serves as the drive for the clamping sleeve 28 and thus the shaft that is inserted into the clamping sleeve attached to the circulating belt 13. Due to the different dimensions of the anchor hook 72 by the screws 54 with the stand, the thread is alternately firmly connected. The shaft 55 of the rotary magnet ² S nately in front of and behind the slotted portion 77 52 is stored by means of the wedge 56 with the clamping. The sleeve 28 stored behind the anchor hook 72 is connected in a rotationally fixed manner. The thread stays on the partial wave, and the one in front of the The control of the rotary magnets 52 for the part anchor hook 72 deposited thread is stripped off at the next wave depending on the movement of the advancement of the anchor hook 72 from the slotted thread feeding tape 13 with the 3 ° head end 77 of the part shaft located on it and arrives at the thread guide so that when dealing behind the relevant partial wave. The same thing takes place from the thread around the guide rollers 5 and 6, a thread change in which a cross is formed on the same side of the machine. If a chain length is desired located part of the shaft. The short projection 58 α am, which is responsible for handling the thread around the deflection catch hook 58, has the task of ensuring that the running Fawalzen corresponds, if the crosshair does not jump out of the hook prematurely. He speaking rotation of the partial shafts 26 and 27 between works with the hook 72 and the draw hook 71 see these partial shafts formed. However, if on together, so that the thread can be made into a longer chain by this projection of the machine, it is deposited safely behind or in front of the hook 72, in particular in a multiple of the chain length during the changing process. The thread is easy to handle, so with the help of a cross-feed of the roller belts 9 in the pulse reducer (not shown) the formation of the direction to the clamping point of the partial shafts transporder crosshairs is switched off by the partial shafts. When warping multiple warp lengths, 26 and 27 will be transferred to the neutral position. The anchor hooks 72 are arranged one below the other In the embodiment of FIG. 5 is the partial operation of the partial waves by corresponding DRE shaft 26 c with respect to the tie rod 71 with the hung same about its longitudinal axis, so that a hook-shaped seal 72, which Rück2Ugfeder 73 reticle only at the beginning and end of the multiple and the solenoids 74 is formed in the same way multiple thread circumference. If after 5 ° as in Fig. 4. The on the frame part 2 out-completion of the chain thread pairs only those removably mounted partial shaft 26 c is separated by cutting at the free end threads, which are provided with a cone 78, from which the hook 72 at the beginning and at the end of the multiple chain circulation of the Tie rod protrudes. The control for the leg when the crosshairs are run in, so an action of the tie rod can be pulled off alternately with the sub-chain on the sample chain winding machine, 55 mutually supported partial waves are also carried out with the length a multiple of the simple means of a rotary counter and a photocell as well Chain length corresponds. The corresponding circuit of a changeover switch controlled by this, through which and control of the rotary magnets 52, can be pushed forward alternately by means of the hooks 72 of the aforementioned two partial shafts customary electrotechnical or electronic.
