    The invention relates to the textile industry, and in particular to a heald for a shed-forming mechanism of a loom for producing three-dimensional fabrics.
    Known heald shaft shedding 'loom mechanism for generating three-dimensional fabric, made in the form of an elongate plate mounted in a guide mechanism with a WHO-0 possibility of moving in the directions of shedding and weft insertion and having a' nose portion with eye for the yarn at the end thereof and a fixing portion with parallel ribs, protruding above the nasal section on one side and in contact with the guides of the mechanism £ 1].
    A disadvantage of the known device 2 θ is the inability to ensure reliable operation of the shed forming mechanism in the development of three-dimensional fabrics on fast-automatic machines. 25
    The purpose of the invention is to increase the reliability.
    This goal is achieved by the fact that in the heap of the shed forming mechanism of the loom for the production of three-dimensional fabrics, made in the form of an elongated plate mounted in the guide mechanism with the ability to move in the directions of yawning and laying the weft thread and having a bow and mounting section with parallel ribs protruding above the nose section on one side and contacting with the guide mechanism, the fixing section of the heald is made with a constant cross-section and on the side, prot vopolozhnoy serving, has a groove to accommodate the guide mechanism, and the bow portion is formed with a cross section decreasing towards the porthole, wherein the maximum thickness of the nose portion is less than the thickness of the fixing portion.
    In this case, the nasal section in the eye area is made with edges bent in opposite directions from the longitudinal plane of the plate, and its end is rounded.
    In addition, the fastening section is smoothly interfaced with the nasal section of the concave surfaces and its freedoms; at least a mega-group of the main threads is used, which is diagonal with respect to the fabric line and intersecting which end is rounded and beveled on the sides.
    Figure 1 presents a perspective image of a heald; figure 2 is a perspective image of a number of heatsinks in conjunction with the guides of the shedding mechanism; Fig. 3 nasal patch; figure 4 section aa in figure 1.
    Remizka 1 is made in the form of an elongated plate and is intended for the manufacture of three-dimensional fabrics of which there are one single longitudinal group of the main thread, and also pass diagonally. relative to the longitudinal line of the fabric.
    The machine for manufacturing three-dimensional fabric includes a device 2 for separating the warp into parts for obtaining Ze®a, which provides longitudinal movement of the weft row of hems in the process of separating the warp into parts, and a device 3 for moving the hems along the weft threads to move the corresponding 4 main threads diagonally manufactured fabric. The remixes are arranged in such a way as to interact with the opposite identical row of heels (not shown) for re-separation into the ’part of the base V passing through the headers to the fabric covering.
    The weaving machine is also equipped with appropriate guiding means 5 for healds, which interacts with the device 3 for guiding 40 the corresponding row of healds in accordance with yaw formation. The pharynx can be obtained when the hems are in either the fully retracted position or the fully extended position, although the main threads are adjacent to one side of the plane of the fabric covering, when the hems occupy one of the open pharynx positions, and the main threads intersect and are adjacent to the other side of the plane hardened the tissue when the heels take a different position of the open pharynx.
    The device 2 for separating the base for obtaining the pharynx may include a separating rod 6 extending in the direction of the weft threads (shown in FIG. 2 as being in the extended position of the open pharynx). The rod 6 can move forward and backward and has an elongated protrusion or rib 7 extending towards the weft threads, which serves for mutually renewed threads 4 in the three-dimensional fabric.
    so that a dense three-dimensional fabric, to cut 10 10
    5Ώ actions with each of headers 1 in the corresponding row.
    The dividing rod .6 may be located under the device 3 for moving the heald blocks. The device 3 is made in the form of an elongated part in the direction of the weft yarns and a moving heald rod 8, provided with protrusions 9, which are shown extending downward from the rod 8 in the direction of the separation rod 6. The protrusions or sidewalls 9 are spaced in order to form passages or 10 holes between them, which serve to receive the protruding parts of the respective heatsinks. Thus, the rod 8 for moving the heald serves also as a movable guide part for heald. The distance between the centers of adjacent slots 10 in the rod 8 for displacing the heald determines the distance between the centers of adjacent
    It was necessary to get such lags quite close together and the hems were relatively thin so that they could be properly guided in the slots 10 during the operations of dividing the base into parts to obtain a pharynx.
    The means 5 for directional supply of the heald can be oblong, going in the direction of the weft threads of the part or the rod 11, which can be fixedly fixed. The rod 11 is provided with a row of protrusions or sidewalls 12 that protrude, fall down and with a gap forward from. of corresponding protrusions 9 of the separation rod 8 for biasing the heald. The protrusions 12 of the rod 11 for the directional supply of the headers define the slots or slots 13 between them, which extend forward and backward and are located in a line with the slots 10 of the device 8 for moving the healds during any current interaction of any of the healds with slots 10 and 13 in both rods 8 and 11.
    The separation device 3 for moving the heald block may contain appropriate means (not shown) for communicating movement or progress to the dividing rod 8 for moving the heald in the same weft direction and relative to the guide rod 11 by a distance equal to the sum of the distances between the centers of adjacent slots 10 in accordance with the backward movement of the dividing rod 6 and the heap. from a fully extended position (figure 2), to the floor
    9730 32 bone stowed position depending on a given order of operations.
    To ensure the operation of transferring each subsequent heald from the front end of a row of hedges to the rear end of an identical row of 5 opposite headers (not shown) behind the cache-active displacement by the weakening stroke of the rod 8, an appropriate means of moving the healds can be used for this purpose. Since 10 such an opposite row of heaps can be mixed in the opposite weft ’direction from the row shown in FIG. 2, consecutive front heaps can be carried out from the opposing row of 15 heaps to the rear end of the row. Following each active (movement of the biasing rod 8 and after the subsequent forward movement of the separating rod 6 and the reamers 1 to 20 in the extended position, the rod 8 can be informed of the movement in the opposite weft direction in order to return it to its original position. 25
    The remixes 1 should be located out of engagement with the stationary guide rod 11 during any weft movement of the headers, which is carried out due to the interaction of the headers 1 with the slots 10 of the rod 8 during the active stroke of the dividing rod 8. And vice versa, the headers 1 should be in full position 35 or in the forward process to the indicated position, approaching the fully extended position, when there was no passive weft movement of the rod 8 to the initial position of the heald. Therefore, the headers 1 are in sliding interaction with the stationary guide rod 11 and therefore must be out of engagement with the mixing rod 8 in the process * 5 of each passive stroke of the rod 8.
    Each heald is an elongated structure, which can be made of any material suitable for this purpose, 50 which does not deteriorate due to changes in the temperature and / or humidity of the environment, for example, plastic or any other metal, t but it is preferable to produce from tape stainless steel.
    Depending on how close to each other the main threads should be located to obtain the desired plane of the three-dimensional fabric, heald 1 can have a thickness in the range of 0.380.81 mm, length 95-127 mm and the width of the main part 9.525-12.7 mm.
    Each heald 1 is made in the form of an elongated plate with a fixing section 65 of a constant width 13, the continuation of which is an elongated, less wide front part 14, which may have a width two times smaller than the width of the fixing section 13, and it ends with a nose section 15, which also narrowed compared with the mounting section: 13 and is made rounded or in the form of a half ring (figure 1). Section 15 is provided with an opening or eyelet 16, which serves as a guide for the corresponding main thread, and since the latter can be in the form of textile yarn and pass along section 15 during its movement through hole 16 during fabric manufacturing, the nose section 15. at least partially offset, and these offset parts 17 form an opening 16 between them, which eliminates the possibility of abrasion of the main thread 4 when it passes through the guide hole 16.
    Since the nose portion 15 of each of the hems 1 is at least partially bifurcated to form a hole 16 at the bifurcation location, it is preferable that the distance between the outer surfaces of the parts 17 when measured in the transverse direction relative to the toe 15 is no more than the thickness of the heald portion 13. Therefore, the elongated front portion 14 of the heald 1 can be narrowed, as indicated by the position 18 in the direction of the free end, as a result of which part of the length of the strip material defining the portion 15, significantly less thickness than the thickness of at least the rest of the length of the main part of the heald 1.
    The mounting section 13 of the heald 1 has opposite parallel longitudinal ribs 19 and .20 (figure 1). As at least the middle part of the heald is wider than the front part 14 and the section 15 of reduced width, and the part 14 of heald 1 is offset from the first rib 19 in the direction of the second rib 20, then the rib. 19 thus defines a protruding part or protrusion 21 at least in the middle section of the heald, which extends along one edge of this part. Preferably, the rib of the narrowed front portion 14 extending in the opposite direction from the protruding portion 21, i.e. the lower edge of the front part 14 was a continuation of the second longitudinal rib 20 of the mounting section 13 of the heald 1.
    In addition, the heald is equipped with means for interacting with other parts of the machine to move the heald in the longitudinal direction. To do this, the back of each remise
    Ί ki 1 is provided with a groove 22, which includes the elongated rib of the device 2, for example, for the purpose of communicating the longitudinal or shedding movement of the heald 1. The hook-shaped protrusion 23 is integral with the plot 5 13 of the heald, forming the rear end of the heald 1. It is preferable that the hook-shaped protrusion 23 partially determined in cut 22 and ended near a plane adjacent to the second longitudinal 10 rib 20 of section 13 of heald 1 so that when the cutout 22 and the protrusion 23 interact with the dividing rod 6 (Fig. 2), the dividing rod 6 and the longitudinal rib 20 each | heddle 5 can be set in the position of the sliding interaction with the corresponding flat guide surface which is represented by a fixed guide 24 tiles.
    o The hook-shaped protrusion 23 is designed to engage it with the rib 7 of the device 2. In addition, the cut-out 22 and the hook-shaped protrusion 23 of each heald 1 are easy to move in the weft direction along the rib 7 of the shedding rod 6 at any time when the heald moves along the weft threads using the rod 8 to move the heatsink, as shown in figure 2. The shape of the groove 22 and the protrusion 23 may be different in relation to the shed forming device used in the loom.
    The distance between the upper surface of the stationary guide plate 24 and those surfaces of the rods 8 and 11, from which the corresponding protrusions or sides 9 · and 12 extend, may be · slightly larger than the width of the part 13 of the heald 1. Thus, the first longitudinal or upper ribs 19 of the part 13 of the heald can be moved during their sliding interaction with the guiding slots 10 and 13 for the heald 1, and the heald 1 can be slidably supported by its ribs 20 on the upper surface of the stationary guide tile 24.
    Since it is preferable that the longitudinal ribs 19 and 20 of each heald 1 are parallel, the heeldoms can be properly engaged with the corresponding parts 55 when occupying or any desired position (inclined, horizontal or vertical). For example, the design shown in Fig. 2 can be positioned in such a way that the separation 6, the moving 8 and the guiding 11 rods and headers are turned upside down, and installed below the stationary guide plate 24. With this inverted position> - ^ 5, the tabs 9 and 12 are positioned upward of the rod 8 for moving the healds and the guide rod 11, respectively, and the healds 1 in this case, when moving, slide their first longitudinal ribs 19 on the connecting sidewalls of the slots 10 and 13.
    Thus, the ribs 19 and '20 serve as oppositely spaced and parallel longitudinal edges for the heald 1, as a result of which the heald can be selectively positioned with any longitudinal edge on the surface to ensure the heald slip.
    Since the protruding parts 21 of the healdges are included in the slots 10 and 13 of both respective rods, the length of the protruding part 21 of each heald is such that it protrudes from the length of the protrusions 9 and 12, so that the protruding parts 21 can be disengaged from the protrusions 12 of the stationary guide rod 11 for remizing and enter into engagement with the protrusions 9 of the rod 8 to move the remiz in the course of each movement of the remizok 1 under the action of the rod b to separate the base into parts from the extended position in full new position. Thus, the protruding parts 21 of the heald are positioned so as to allow the rod 8 to feed the heald 1 in the direction of the weft threads of the loom relative to the stationary "guide rod 11.
    Since the front portion 14 of each heald 1 is narrowed relative to the fastening portion 13 and is further offset from the first longitudinal rib 19 towards the second longitudinal rib 20, the elongated front part 14 of each heald is spaced from the protrusions 12 as the protruding parts from the fastening section 13 of the heatsink come out of the slots 13 and enter the slots 10 ·. Those. narrowed front parts 14 of the hems are located between the stationary plate 24 and the stationary guide rod 12, while these parts do not interact with the protrusions 12 when the hems take up the fully retracted position of the open pharynx.
    When the headers 1 occupy a fully retracted position, their front ends 15 are located inward or forward, i.e. to the left of the stationary guide rod 11 and the guide tile 24 so as to prevent tearing of the main threads 4 due to their engagement with the stationary guide rod 11 and / or plate 24.
    Even when the hems 1 occupy the last of these positions in the process of their movement in the direction of the weft threads, it should be noted that the narrowed front part 14 of the heald 1 is outside the shaft 11 ,. as a result of which, 5 a constipation is formed for the cuts and a precise movement of the straps past the guide slots 13 is provided with the help of the moving rod 8. 10
    However, before the subsequent movement of the rod 8 goes in the opposite direction and returns to its original position, the healds 1 can be moved inward so that the protruding parts 21 of the heald can be brought out of interaction with the displacement rod 8 as the rib 7 on the dividing rod 6, it engages and pushes in front the rear 'J0 surface of the part 13 of each heald, this surface being defined by a groove 22. Thus, the heel 6 brings the heald 1 to its fully extended position. 25 projecting portion 21 of the heald frames 1 are introduced in sliding engagement with the slots 13 and along these openings when the rear ends of the heald frames 1 are output completely from the interaction with peremeschayu- vn conductive rod 8. The rod 8 is then moving can return to its initial position, during which the heats 1 remain in the desired spatial arrangement relative to each other using the guide bar 35. The operation is repeated so that the heats can be moved sequentially in the direction of the weft threads of the loom so as to locate the main tee 40 ni- diagonally with respect to the manufactured fabric.
    To facilitate the directional supply of the protruding part 21 of each remiz-45 ki 1 to the corresponding guide slot 13 of the guide rod 11 during each movement forward of each remiz from the retracted position to the extended position, it is provided that each protruding part 21 has a leading edge 25 of reduced thickness, and this edge is beveled or rounded at the point of its passage into the front narrowed part 14 of the heald 1. In addition, it is preferable that the thickness of the edge 26 of the rear end of the heald 1 is less than m, the thickness of the fastening section, for example, by beveling or rounding, in order to facilitate 60 directed feeding of the protruding part 21 of the heald into the corresponding slot of a series of guiding slots 10 in the transferring rod 8 during longitudinal movement of the corresponding 65 healds 1 when moving backwards , i.e. from left to right (figure 2), In order to further facilitate the directed flow of the protruding part 21 of each heald 1 into the guide slots 10 and 13 from the respective rods, it is preferable that the edges 25 and 26 of reduced thickness are also inclined along a converging line relative to the first longitudinal hems edges 19, with the leading edge 25 of the protruding part 21 generally tilting backward from an adjacent longitudinal edge of the leading part 14, the trailing edge 26 is usually tilted forward from the outer surface of the hook. ridge 23.
    With a temporary arrangement of the separation rod 6 behind the transferring rod 8 of the healdock 1, the latter can be easily installed so that the cutouts 22 and hook-shaped protrusions 23 will mesh with the edge 7 of the rod 6. Then, by moving the separation rod 6 forward, the protruding parts 21 of the heald can be easily installed in line with the slots 10 and 13 and feed them into these, the slots when setting up the machine for work on the manufacture of three-dimensional fabric. If necessary, each heald 1 can have a corresponding through hole, for example, in the form of a groove 27 made in the fastening section 13 of the heald, which serves to facilitate proper installation and / or fixing of heald 1 in the manufacturing process.
    The proposed remiza has a more perfect design, can move longitudinally in the process of performing operations to divide the base into parts to obtain a pharynx and transversely, “ie along the weft threads, and to ensure reliable operation of the shed forming mechanism at a high-speed operation mode of the machine.

    The invention relates to the textile industry, namely, a heel length. a shedding mechanism of a weaving machine for making three-dimensional fabrics.  The known remise of the shedding mechanism of the weaving machine for generating three-dimensional fabrics is made in the form of an elongated plate mounted in the guide mechanism with the possibility of moving in the directions of forming the yarn and laying the weft yarn and having a nose section with an eye for the thread at its end and a fastening section with parallel rerami, protruding above the nasal area on one side and in contact with the guides of the mechanism 1.  A disadvantage of the known device is the impossibility of ensuring reliable operation of the shedding mechanism when generating three-dimensional fabrics on high-speed automatic machines.  The purpose of the invention is to increase the reliability of work.  The goal is achieved by the fact that.  in a shedding mechanism of a weaving machine for working three-dimensional fabrics, made in the form of an elongated plate, installed in a guide mechanism with the ability to move in the directions of forming and laying the weft yarn and having a nose and fastening section with parallel edges, protruding above the nose section with one of its side and in contact with the guide mechanism, the mounting portion of the shank is made with a constant cross section and on the side opposite to the protruding part has a groove d The guide mechanism is located at the location of the guide mechanism, and the nose section is made with a cross section that decreases towards the eye, while the maximum thickness of the nose section is less than the thickness of the fixing section.  In this case, the nasal portion in the area of the eye is made with edges bent in opposite directions from the longitudinal plane, and its end is rounded.  In addition, the fastening section is smoothly mated with the nasal section by concave surfaces and its free end is rounded and chamfered.  FIG. Figure 1 shows the perspectives of her image of a res14ieki; in fig.  2 is a perspective view of a p and a shank in conjunction with the guides of the shedding mechanism; in fig. H Nose stretch; in fig. 4 section A-A in FIG. 1.  Remizka 1 is made in the form of an elongated plate and is intended for the manufacture of three-dimensional fabrics in which at least one group of main threads is used, extending diagonally relative to the longitudinal line of the fabric and crossing another group of main threads that also pass diagonally relatively longitudinal fabric lines.  The three-dimensional fabric making machine includes a device 2 for dividing the base into parts for receiving the throat, which provides longitudinal movement of the pe / I of the weft row in the process of dividing the base into parts, and a device 3 for moving the shafts along the weft threads for moving the respective main threads 4 along the diagonal of the fabric being manufactured, Remizki are arranged in such a way as to interact with the opposite identical row of shims (not shown) for re-dividing you V, extending through the healds to zastilu manufactured fabric.  The loom is also equipped with an appropriate helix guiding means 5, which cooperates with the device 3 for direct feeding of a corresponding series of shafts. OK in accordance with the formation of a pharynx Zev can be obtained when the shafts occupy either a fully retracted position or completely. The extended position, although the main threads are adjacent to one side of the plane of the fabric, when the shims occupy one of the open mouth positions, and the main threads intersect and lie adjacent to the other side of the flat surface of the fabric, when the shims occupy another position of the open pharynx.  A separation device 2 for preparing the pharynx may include a dividing rod going in the direction of the weft yarns (in FIG.  shown as occupying the open position of the open pharynx).  The rod 6 can be moved back and forth and has a protrusion or rib 7 extending in the direction of the weft yarns, which serves to interact with each of the shims 1 in the corresponding row.  The dividing rod ,, 6 may be located under the device 3 for moving the shafts.  The device 3 is made in the form of an elongated in the direction of the weft threads and a heddle-moving part or rod 8, provided with protrusions 9, which are shown extending downward from the rod 8 in the direction of the separator.  Stern n 6.  The projections or sidewalls 9 are spaced in order. to form passages or slots 10 between them, which serve to receive the protruding parts of the respective shafts.  Thus, the shaft 8 for moving the shroud also serves as a movable guide part for the shim. The distance between the centers of the adjacent slots 10 in the rod 8 for displacing the hem op. determines the distance between the centers of the adjacent base threads 4 in the three-dimensional fabric being manufactured.  Thus, in order to obtain a dense three-dimensional fabric, it is necessary that the slits 10 are located quite close to each other and the shims are relatively thin so that they can be properly guided into the slits 10 during the process of dividing the base into parts. for receiving a pharynx.  The means 5 for the directional feeding of the shafts may have the shape of an elongated part or rod 11 extending in the direction of the weft yarns, which may be fixedly mounted.  The rod 11 is provided with a series of protrusions or sidewalls 12, which protrude downward and spaced forward from the respective protrusions 9 of the separator rod 8 to displace the heddle.  The protrusions 12 of the rod 11 for directional feeding of the shafts define slots or slots 13 between them, which go forward and backward and are placed in line with the slots 10 of the device 8 to move the shafts during any ongoing interaction of any shafts with slots 10 and 13 in both rods x 8 and 11.  A separation device 3 for moving shafts may contain appropriate means (not shown) for maintaining movement or movement to the dividing rod 8 for moving the shim in one weft direction and relative to the guide rod 11 by a distance equal to the sum of the distances between the centers of adjacent slots 10 according to the backward movement of the separating rod b and the shank from the fully extended position (Fig.  2), fully retracted position depending on the set of orders of operations. To ensure the operation, transfer each subsequent heddle from the front of it to the back of the row of shafts to the back end of an identical to the number of opposite shafts (not shown) behind the active offset of the weft stroke of 8 you can use the corresponding.  appropriate, for this purpose, the movement of shafts.  Since such an opposite series of shafts can be mixed in the opposite direction of clarification from what has been shown in FIG.  2 p yes, consistent front re. The bars can be made from the opposing row of shafts to the rear end of the row.  Following each active movement of the rod 8 and after the subsequent forward movement of the dividing rod 6 and the shims 1 in, it is advanced. It is possible to tell the rod 8 to move in the opposite direction of the weft direction in order to return it to its original position.  Remixes 1 must be placed out of engagement with the stationary guide rod 11 j in the process of any weft movement of the shafts, which is carried out by the interaction of the shafts 1 with the notches 10 of the rod 8 during the active stroke of the dividing rod 8.  Conversely, the shafts 1 must be in the fully extended position or, in the course of the forward stroke, to the specified position, approaching the fully extended position when the passive weft movement of the rod 8 does not occur in the initial position of the shim.  Consequently, the shafts 1 are in sliding interaction with the stationary guide rod 11 and therefore must be out of engagement with the mixing rod 8 during each passive stroke of the rod B.  Each shim is an elongated structure that can be made from any suitable material for this purpose that does not deteriorate when the temperature and / or humidity of the environment changes, such as plastic or any suitable metal, but it is preferable to make shims of ribbon non-aging steel. Depending on how close the main threads should be to each other to obtain the desired plane of the three-dimensional fabric, the hem can have a thickness in the range of 0.380, 81 mm, length 9 5-127 mm and the width of the main part of 9.525-12.7 mm.  Each shim 1 is made in the form of an elongated plate with a fastening section 13 of constant width, the continuation of which is an elongated, less wide anterior part 14, which may have a width that is two times smaller than the width of the fastening section 13, and ends with a nose section 15, which the second is also narrowed in comparison with the mounting area; 13 and is rounded or in the form of a semi-ring (FIG. one).  Section 15 is provided with a hole or eye 16, which serves as a guide for the respective main thread, and since the latter can be in the form of textile yarn and pass along section 15 as it moves through hole 16 during fabric manufacture, the nose section 15 is at least partially offset, and these offset portions 17 form an opening 16 between them, which eliminates the possibility of abrasion of the main thread 4 as it passes through the guide hole 16.  Since the nose section 15 of each trimming 1 is at least partially bifurcated with a hole 16 at the splitting point, it is preferable that the distance between the outer surfaces of the parts 17 when measured in the transverse direction relative to the nose 15 is no more than the thickness of the shimding section 13.  Therefore, the elongated front portion 14 of shim 1 can be tapered, as indicated by position 18 in the direction of the free end, with the result that part of the length of the strip material defining section 15 has a much smaller thickness than at least the rest of the length of the main part of shim I .  The fastening portion 13 of shim 1 has opposite parallel longitudinal ribs 19 and. 20 (FIG. one).  As at least the middle part of the shim is wider than the front part 14 and the section 15 is of reduced width, and part 14 of the shim 1 is offset from the first edge 19 in the direction of the second edge 20, then the edge.  19 thus defines a protruding portion or protrusion 21 at least in the middle portion of the heddle, which extends along one edge of this portion.  Preferably, the rib of the constricted front portion 14 extending in the opposite direction from the projecting portion 21, i.e. e.  the lower edge of the front part 14 was a continuation of the second longitudinal rib 20 of the fastening portion 13 of shim 1.  In addition, the heddle is provided with means for interacting with other machine parts to move the hem in the longitudinal direction.  For this, the rear part of each shim 1 is provided with a groove 22, into which the elongated edge of the device 2 enters, for example, in order to communicate the longitudinal or shedding movement of the shim 1.  The hook-shaped stage 23 is integral with the pitch section 13, forming the rear end of the panty 1.  Preferably, the hook-shaped protrusion 23 is partially defined 22 and terminates near a plane adjacent the second longitudinal edge 20 of the section 13 of the shim 1 so that, when the notch 22 and the protrusion 23 interacts with the dividing rod 6 (FIG. 2) the dividing rod b and the longitudinal edge 20 of each heddle could be installed in the position of a sliding interaction with the corresponding flat guide surface, which was presented on the stationary guide tile 24.  The hook protrusion 23 is intended to engage it with the edge 7 of the device 2.  In addition, the notch 22 and the hook-shaped protrusion 23 of each strand can easily be moved in the weft direction along the rib 7 of the shed forming rod 6 at any time when the shims are moved along the weft yarn with the help of the shank 8 to move the shims, as shown in FIG. 2   the groove 22 and the protrusion 23 may be different with respect to the shedding device used in the loom.  The distance between the upper surface of the stationary guide plate 24 and those surfaces of the rods 8 and 11, from which the corresponding protrusions or sidewalls 9 and 12 extend, may be somewhat larger.  than the width of part 13 of shims 1. Thus, the first longitudinal or upper ribs 19 of part 13 of the shims can be moved when they slide together with the guide slots and 13 for shims 1, and the shims can slidly rest upon their movement by the fins 20 on the upper surface of the stationary guide tile 24.  Since it is preferable to.  the longitudinal ribs 19 and 20 of each shim 1 were parallel, the shims can be properly engaged with the corresponding parts during the occupation or at any desired position (inclined, horizontal or vertical).  For example, the construction shown in fig. 2, can be positioned in such a way that the separating b, moving and guiding 11 rods and shafts will be inverted, and installed below the stationary guide n. feed us 24.  With such an inverted arrangement, the protrusions Ei 12 are located upwardly of the rod 8 to move the shafts and the guide rod I, respectively, and the shafts 1 in this case, when moving, slide their first longitudinal ribs 19 onto the connecting sides of the slots 10 and 13.  Thus, the ribs 19 and 20 serve as opposed and parallel longitudinal edges for heddle 1, with the result that the heddle can be selectively placed on any longitudinal edge. surfaces with a slip slip.  Since the protruding portions 21 of the shafts fit into the slots 10 and 13 of both respective rods, the length of the protruding portion 21 of each heddle is such that with respect to the length of the projections 9 and 12 with respect to the distance from the projections 9 to the projections 12, that the protruding portions 21 can be derived from meshing with the projections 12 of the stationary guide rod 11 for hedging and engaging with the projections 9 of the rod 8 to move the hedging during each movement of the helix 1 under the action of the rod b to separate the base into parts from the extended position in Tew retracted position.  Thus, the protruding portions 21 of the shims are positioned so as to allow the rod 8 to feed the shafts 1 in the direction of the weft threads of the loom relative to the stationary guide rod 11.  Since the front part 14 of each shim 1, is narrowed relative to the fastening section 13 and, moreover, is offset from the first longitudinal edge 19 in the direction of the second longitudinal edge 20, the elongated front part 14 of each shim is spaced from the protrusion 12 as the protruding the parts from the fastening portion 13 of the shafts exit from the slots 13 and are included in the slots 1U.  T. e.  The tapered front portions of the shims 14 are located between the stationary plate 24 and the stationary plate. the guide rod 12, while these parts do not interact with the protrusion 12 when hemming the fully retracted position of the open mouth.  When the shafts 1 occupy a fully retracted position, their front ends 15 are located inward or outward. red, t. e.  to the left of the stationary guide rod 11 and the guide plate 24 so as to prevent rupture of the main threads 4 by hooking them to the stationary guide rod 11 and / or the plate 24.  Even when remises 1 occupy the last of these positions in the course of their movement in the direction of the weft yarns, it should be noted that the narrowed front part 14 of the shims is out of the rod I, resulting in constipation for shafts and provides weft movement of the shims past 13 by means of a moving rod 8.  However, before the subsequent movement of the rod 8 in the opposite direction and returning to its original position, the shims 1 can be moved inwards so as to pull the protruding parts 21 of the shims out of interaction with the moving rod 8 as the rib on the dividing rod b the engagement engages and pushes the rear surface of the part 13 of each shim from the front, and this surface is defined by the groove 22. Thus, the rod b feeds the shims 1 into the fully extended position.  The protrusions of the 21 shafts 1 are introduced into a sliding engagement. with slots 13 and along these holes when the rear ends of the shafts 1 are completely out of engagement with the displacement rod 8.  Then the moving rod 8 can return to its original position, during which the shafts 1 remain in the desired spatial arrangement relative to each other with the help of the guide rod 11.  The operation is repeated so that the shims can be sequentially moved in the direction of the weft yarns of the loom so as to position the main yarns diagonally with respect to the fabric being produced.  In order to facilitate the guided supply of the protruding part 21 of each heddle 1 to the corresponding guide slot 13 of the guide rod 11, during each forward movement of each heddle from the retracted position to the extended position, it is foreseen that each protruding part 21 has a front edge 25 of reduced thickness this edge is made skhdna or rounded at the point of its passage into the front narrowed part 14 of shim 1.  In addition, it is preferable that the thickness of the edge 26 of the rear end of the shim 1 is less than the thickness of the fastening section, for example by beveling or rounding, so as to facilitate the directional feeding of the protruding part 21 of the shim to the corresponding slot of a series of guide slots 10 the moving rod 8 in the process of longitudinal movement of the corresponding shafts 1 when moving backward, t. e.  from left to right (fig. 2) In order to further facilitate the directional feeding of the protruding part 21 of each heddle 1 into the guide slots 10 and 13 from the respective rods, it is preferable that the edges 25 and 26 of a reduced thickness are also inclined along the converging line relative to the first longitudinal edge 19 heddle , the front edge 25 of the protruding part 21 is usually inclined backward from the adjacent longitudinal edge of the front part 14, the rear edge 26 is usually inclined forward from the outer surface of the hook-.  23  With temporary arrangements of the dividing rod 6 at the rear of the displacing rterzh 8 shafts 1, the latter can be easily installed so that the notches 22 and the hook-shaped protrusions 23 will engage with the edge 7 of the rod 6.  Then, moving the dividing rod 6 forward, the protruding parts 21 of the shims can be easily installed in line with the slits 10 and 13 and fed to these slits when setting up the machine for working on the fabric of three-dimensional fabric.  If necessary, each shim 1 may have a corresponding through hole, for example in the form of a groove 27, made in the shim fastening section 13, which serves to facilitate proper installation and / or fixing of the shims 1 during their manufacture.  The offered hem has a more perfect design, can be moved longitudinally in the process of performing operations for dividing the base into parts to obtain the pharynx and transversely, t. e.  along the weft threads, and ensure reliable operation of the shedding mechanism at the high-speed mode of the machine.  Claim 1.  Remizka of the shedding mechanism of the weaving machine for producing three-dimensional fabrics, made in the form of an elongated plate installed in the guide mechanism with the ability to move in the directions of forming and laying the weft yarns and having a nose section with an eye for the thread at its end and the fastening section with parallel edges, acting on the nasal section on one side of it and in contact with the mechanism of the Shay mechanism, so that, in order to increase the reliability of the work, the fixing section is with a constant cross-section and
    on the side opposite to the protruding one, has a groove for accommodating the guide mechanism, and the nose section is made with a cross section, reducing the direction toward the eye, while the maximum thickness of the nose section is less than the thickness of the fastening section.
