    The invention relates to the textile industry, in particular, to a device for preparing a weft yarn on a weaving loom with a wave-shaped shed containing a weaving roto with combs for inserting the weft yarn and dam for the weft yarn, at least one measuring roller for constant measuring and feeding the weft yarn , sheath) to cut the introduced weft yarns and a device for inserting weft yarns into the ridges for insertion; , weft yarn weaving rotor.
    The purpose of the invention is to increase the reliability of the device.
    FIG. 1 shows a device for preparing a weft yarn in isometric view, FIG. 2 - scissors in isometry; in fig. 3 and 4 — parts of the weft yarn; figure 5 (CL, J) is a schematic representation of the process of preparing the weft yarn.
    The main components of the device (Fig. 1) are a weaving rotor 1 with orienting and surf crests 2, a fixture 3 for measuring the weft yarn, a means 4 for cutting the laid weft yarns and a fixture 5 for directing the weft threads to the orienting crests A tool3 for measuring the weft yarn contains four measuring rollers 6,7, 8 and 9 for continuous measuring and feeding the weft yarns installed with the possibility of free rotation on the axis x 10 and driven in rotation
    friction disk 11. The tool for cutting the laid weft yarns contains scissors 12, 13, 14 and 15 assembled in a single holder 16.
    Each scissors (FIG. 2), for example 12, has a pneumatic tube 17 for feeding the weft yarn. To the four pneumatic tubes, compressed air from the common channel 18 is supplied from
    pneumatic systems of the machine. It passes through a channel 19, angled to the pneumatic tube 17, and a longitudinal slot 20 in the wall of the pneumatic tube 17. The weft thread is sucked into the pneumatic tube and fed to the weaving rotor 1.
    The pneumatic tube 17 is provided with a cutting edge 21 interacting with the stationary cutting member 22. This cutting member 22 has a lateral recess 23 for each pneumatic tube for passing the weft yarn. Pneumatic
    the tube is provided at its other end 24 with a protrusion 25, one side 26 of which can slide up and down in the guide 27 of the bracket 28. The cutting movement, respectively, the forward movement of each pneumatic tube is provided by the cutting lever 29 .. The latter is fixed on the axis 30 entering the gearbox 31 of the weaving machine, and is directed to
    it through the lever and the follower roller on the cam washer (not showing ana). The end of the cutting lever 29 is equipped with two pins 32 and 33, located 1 min at the height of the inlet 34 of the device 5
    for guiding the weft yarn. Thus, each time the protrusion of the pneumatic tube, which is located in front of the inlet 34, is covered. The means 4 for cutting the laid weft threads rests on the rod 35, which is movable up and down with the help of the lever 36. The lever 36 is mounted on a shaft, which is inserted into the gearbox 31 and directed through the lever and the follower roller on the cam disc (not shown). The cam disc of the gearbox is shaped so that the rod 35 moves the cutting device down in such a way that the scissors 12, 13, 14 and 15 take up space in front of the input 34 of the device for directing the weft yarn. After that, the bar lifts the means 4 for cutting back to its original position so that the nubs 15 are again in front of the entrance 34. The device 5 for guiding the weft yarn consists of a body 37 rigidly fixed on the hinged machine and moving up and down the closing plate 38, which the device for closing and opening, alternately closes and opens the guide channel 3 that opens in the housing and opens on the side facing the weaving rotor 1 Mention the device input 34 To direct the weft yarn to start Channel 39 and is located before the exit of the pneumatic tube of those scissors, for example, scissors 12, which with the help of rod 35 occupied places before the entrance 34. The channel exit 40 is located on the path of laying the weft yarns before the entrance ridge for the weft rotor 1. The closure plate 38 rests on shoulder 41 on rmo 42 which periodically raises and lowers with two cam washers 43 and 44. When moving up the frame, the closing plate rises to channel 39, while moving down the plate leaves a channel on the free cable tse open. The return force for the chassis is provided by a spring 45 located in the sleeve 46 on the housing 37. The cam-shaft axes are passed through and driven into the gearbox 31. In the housing 37, in addition, a channel 47 is connected to the compressed air supply system and entering the red line 39 before its outlet 40. The device operates as follows. Suppose that the weaving machine is in operation and the weaving rotor 1 rotates in the direction of the arrow. The measuring rolls 6, 7, 3 and 9 simultaneously remove four weft threads a, b, c, d from the rigidly fixed spare coils. The weft threads pass through the pneumatic tube of each scissors 12, 13, 14 and 15. The rod 35 lifts means 4 for cutting so that the scissors 12 are in front of the entrance 34 of the device for directing the weft thread. The weft threads a, b, c, F enter when the weaving rotor 1 is rotated, for example, through recesses 23 in the cutting element of the respective scissors 12 , 13, 14 and 15 and are located on the way to the corresponding pharynx in the ridges for orientation weft thread of the rotor 1 with an offset of 1 / 4. width of the throat. The weft yarns here, through the edge of the mouth, correspond to a pneumatic tube (in FIG. 2 for weft yarns a in scissors 15). The previous weft thread at this time approached due to the rotation of the Kawstein's pharynx rotor and was introduced across the full width of the pharynx. At this moment the cutting arm 29 moves forward and moves the corresponding pneumatic tube 17 of the scissors 12 along with the weft thread oh forward along the cutting edge 22 of the cutting element 22 so that the exact thread is cut. The remaining thread from the pneumatic tube is drawn by the air flow remaining in the pneumatic tube and sinks as the next weaning to the guide channel 39 closed by the closing plate 38 to guide the weft thread and from there, supported by the air flow from channel 47 to the incoming next a comb for orienting an exact thread of a weaving rotor. The thread does not stop on the path T of the measuring rollers to the weaving and moves continuously at a constant speed. The rod 35 lowers the cutting tool 4 to the half-legs, so that
    the pneumatic tube which leads the weft thread about is located in front of the inlet 34 of the guide channel 39. The loose end of the weft thread and immediately before cutting as the cutting lever 29 moves is gripped by the clamping element, so that the movement of the weft thread is braked before stopping. The weft q is nailed next to the ridge to guide the weft yarn with a surf ridge to the fabric. Thereafter, the locking plate 38 moves backward, so that the newly received weft thread can exit from the guide channel 39 and be gripped by the bore rotor. The specified string f is cut and nailed in the same way as the weft thread ", as described above,
    The cut tool 4 is lowered into the next two stages and weft weft yarn is inserted. Thereafter, the bar 35 lifts the cut pieces to four steps at once, again reaching the starting position with the scissors 12 before entering 34, and the steps described are repeated.
