They wear heavy wear on the planks and are destroyed, the Halevs no longer control the thread of the warp, the latter of of the plotter. In addition, as a result of the unequal size of a gantry, fasteners are warped, having a negative effect on the operation of the device. The purpose of the invention is to reduce the breakage of the main threads and increase the reliability of the device. In order to achieve this goal, the fastening elements of each shroud are connected by at least one flexible element, with the helix mounted slats with a gap. In addition, every fastener ale. The cop is U-shaped. the length of the side sides of which exceeds the maximum displacement of the shafts, and the flexible elements are fastened in the fastening elements with rods. FIG. 1 and 2 schematically depict the proposed shedding device, side view and section; in fig. 3 sheds and plotters in it; in fig. 4 - hemot side view; in fig. 5 the section in FIG. four; in fig. 6 end of the rod; FIG. 7 shows a recess for a bar in a fastener; Fig, 8 - heddle, another option, front view; FIG. 9 is the same side view; in fig. 10 and 11 — means for tensioning the shank. The yaw-forming device contains eccentrics 2 fixed to the shaft 1 (Fig. 1) with successive shifts relative to each other 2, connected by collars 3 with two-arm levers 5 that sit on the axis 5, which are {{}. associated with the uprights 6, located in the rails 7, on each rack 6 mounted fastening element 8, connected to the fastening element 9 gib. KIM element 1O (Fig. 1, 2 and 4,5). . Each of the fastening elements, 8, 9 is made of two connected plates 11, II 12, 12, (Fig. 5, 8), which are installed so that their sides are parallel, while the fastening elements can be U-shaped (Fig , 5). The length of the O. of the sides of the plates 1 11 and 12, 12 is greater than the maximum displacement - and the contacting shafts (Fig. 2), which ensures the constant contact of the sides of the connected shafts. On the side of each plate there is a recess 13 (FIGS. 4, and 8, 9) with a hole (the hole is not indicated) for fastening the strip 14 with eyelets 15 mounted on it, gale lfc) | into the eyes of which the warp threads 17 are formed, forming a wave gap (fig. 3) for plotters 18. The fastening elements 8, 9 can be connected alone, and the flexible element 10 (figs, 4, 5). For this, the flexible element 10 has lugs 19, which are put on the rods 20, mounted in the holes of the recesses 2 Ij made on the sides of the fasteners c of the elements (Figs. 4, 5). Reliable fastening of the slats 14 with galevdmi 16 and their simple removal are achieved by at the ends of the bars 20, grooves 22, and in the recesses 21 - figured-slots 23 (Fig. 6, 7) for fixing and releasing the bars 20. The fastening elements 8, 9 can also be connected by two flexible elements 1O, Then the ears 19 flexible elements 10 are mounted on the limb 24 of the plates 11, 11 and 12, 12 (FIGS. 8, 9). Such fastening of the flexible element 1O allows to reduce the width of the plates 11, II 12, 12 and, consequently, the dimensions of the shaft and shedding mechanism. The number of flexible elements 10 in this case is larger than when using the shims of FIGS. 4, 5, therefore, in the second case, the elimination of the broken threads of the main threads 17 is simplified. The means for tensioning the shimmer is made in the form of an elastic element 2 4 (fig. 10, 11-) (cushioning cord or rubber strands), clamped at both ends in hooks 25, 26. Use as a tool for tensioning the shim of the specified types the elastic elements allows to reduce the height of the heddle system, which facilitates the elimination of the broken threads of the warp 17, the hook 25 (fig. 1, 2) is attached to the rod 27 of the upper link 26 of the machine, and the hook 26 is connected to the creme hem 9 of the heald, with the hook 26 can be put on the bar 29 ($ ir, 8, 9) or entered into the hole ZO fastener 9 (Fig, 4, 5). Rows of fasteners V (9 are separated by guide strips 31 fixed to the upper link of the machine 28; The length of the flexible element 10 is such that there is a vertical gap C between the helixes 16 and the strips 14. For reliable mutual direction of the fasteners The elements 8, 9 of the adjacent reels. 566 width d of the recesses should not exceed the width e of the plate (Fig. 4). The shedding device works as follows: The rotation of the shaft 1 with a set of eccentrics 2 is transformed by collars 3, with two shoulders 4, into reciprocating movement. , and cl consequently, the shim, the tension of which is carried out by the elastic elements 24 through the flexible elements 10. The gap C between the lugs 15galev 16 and the laths 14 allows the lugs 15 of the heel 16 to be positioned along the laths 14 so that the pressure exerted by the glands 16 on the warp 17 is the smallest, which reduces the breakage of the warp 17, When the warp of the warp 17 is broken, the weaver unwinds the Galeb 16 and the flexible elements 10 by a convenient distance, stretching the elastic elements ..24, finds the galevo 16 and starts the thread 17 in his peephole. The numbers of hellwood 16 on the heddle (fig. 8, 9) II are changed by separating the plates 11, 11 and 12 ,. 12, in which the laths and galeva 16 are released. Halev on heddle of FIG. 4, 5 are replaced by compressing the strut against the action of the elastic element 24; the rods 2O come out of the figured slots 23, the rigidity of the retaining is reduced dramatically, which makes it possible to further change the helium 16 in the manner described. After the helium 16 is replaced, the rods 20 are set to their original position. The last variant of fastening the slats 14 is more reliable, since In the working position, the fastening elements 8, 9 possess 97726 rather high rigidity ensuring reliable fixing of the strips 14 in the fastening elements. Using the invention allows reducing the breakage of the main threads and increasing the reliability of the machine, the formula of the invention of a weaving machine with waveform phase movable throat containing shafts, each of which has one located above the other bar with galevy, rigidly installed in fasteners, one of which is kinematically connected to with a shaft drive, and the other with a tool for tensioning it, so that, in order to reduce the breakage of the main thread 20 and increase: the reliability of the device, fasteners: elements of each heddle interconnect at least one flexible element, with the gale5va smontnrsmvany on the slats with a gap. 2. The device according to claim 1, which means that each fastener has a P-oz form, the length of the lateral sides of which makes the value of the maximum relative to the shafts displacements, and flexible elements secured in fasteners by bars.
