    (54) Weaving machine with ripplingly movable along the main thread ZEV
    one
    The invention relates to textile machinery and relates to the design of a loom with a wave-like moving along the main ones.
    tey zeom
    Known weaving machine with a wave-like movable along the main threads with a throat, containing alternately-mounted multi-faceted bearing disks for the main threads and friction disks. Bearing disks ensure the yawning and retention of the main threads and are placed in accordance with the desired weave with the necessary angular displacement one relative to another. The main yarns are fed to the carrier discs from the side through the fixed reed t.l3.
    The disadvantage of this machine lies in the fact that the change of interlacing is associated with the restructuring of the arrangement of the disks on the shaft.
    A weaving loom is known with a wave-like movable along the main threads with a shed that contains shaft-mounted surfing plates and shedding elements for the upper and lower branches of the main threads. In front of the plates
    to the positive direction of arrival of the main yarns, a means for moving the main yarns in the transverse direction is established. The indicated means provides (in accordance with the program) the arrangement of the main threads on one or another shedding element, which obscures the interchange of weaves. Each element is provided for a greater number of main threads than usual. The machine provides a change of weaves without rearrangement of the arrangement of the pharynx 11 elements | 2.
    The disadvantage of this machine is that the main yarns may be unevenly distributed in the intervals between the surf plates entering them, which leads to cuts into the fabric. In addition, the placement of a larger number of main threads on the shedding element necessitates a significant transverse movement of the main threads. At the same time, the course of means for moving the main threads can reach values corresponding to the course of the remise in classical weaving, which reduces the speed capabilities of the machine. Closest to the proposed technical essence and the achieved result. is weaving. a machine with a throat wavy and moving along the main threads, containing breaking plates parallel to each other, uniformly spaced around the circumference of the tissue-forming drum and forming plate ridges along its forming, dividing plates located in the direction of the weft threads between the breaking plates, and component ridges located along the drum-forming, shedding elements for the lower and upper branches of the main threads, alternately arranged between the dividing plates, and vehicle for movement. main threads along the ridges, located in front of the tissue-forming drum. Yawning elements, surf and separation plates are located in each plate ridge. To change the weave, the above tool displaces the warp threads before entering the next ridge. The movement is carried out by an amount sufficient to transfer the threads to the shed forming element of another branch of the throat. The warp threads are inserted precisely into the required gap between the surf plates of the next ridge (i.e., distributed evenly in it), due to their orientation with the surf plates of the previous ridge and the means for moving the main legs L3. The disadvantage of the machine lies in the fact that even if the means for moving the main threads are close to the drum, there is little reliability of the uniform placement of the main threads between the surf plates. The purpose of the invention. - improving the quality of the fabric by increasing the uniform distribution of the main threads. For the implementation of the specified Delhi in the loom with a throat wavy under the main yarn along the main yarns, containing surf plates, parallel to each other and evenly spaced around the circumference of the cloth-forming drum and forming plate ridges along its forming, dividing plates arranged in the direction of the weft threads. plates and component ridges located along the forming drum, shedding elements for the lower and upper branches of the main threads, arranged alternately between the dividing plates and the means for moving the main yarns along the ridges, located in front of the fabric-forming drum, the ridges formed by the dividing plates are displaced along the main yarns relative to the ridges formed by the dyking plates. The fabric-forming drum is made in the form of a pipe with grooves directed along its forming slots for mounting plate-like ridges. The yawning element for the upper branch of the main yarns is made in the form of a hook, bent in the direction following the shedding element, along the path of the tissue-forming drum, the surf plate forming the channel for inserting the weft yarn with the surface of the tissue-forming drum. As a parallelogram, the bottom side of which corresponds in the form of int. Right edge of the hook. Moreover, the ridges including the surf plates / contain spacer plates located between the surf plates, the thickness of the surf plate being equal to the thickness of the separating plate, and the thickness of each shed forming element and the spacer plate is three times larger than the thickness of the surf plate. Figure 1 presents the proposed weaving machine, a cross-section; figure 2 is a view along arrow A in figure 1; on fig.Z - elements of figure 2 on an enlarged scale; in Fig.4 section bb on Fig.2; Fig, 5 - details of the tissue-forming drum, axonometric; in fig. 6 - tissue-forming drum, cross section. The loom with a wave-shaped opening (Fig. 1) moving along the main yarns contains 1, rock 2, 3 means for moving the warp threads 4 along the crests of the tissue-forming drum 5, chest b, valn 7 for picking cloth 8 and the product roller 9. By The circumference of the tissue-forming drum 5 (FIG. 2) along its generators are the lamellar ridges 10 and 11. The lamellar ridges 10 contain surf plates 12 for the weft filaments. The lamellar ridges 11 consist of separator plates 13 located between the shed-forming elements 14 and 15 alternately arranged for the upper and lower branches of the main threads. In this case, the separation plates 13 are located in the direction of the weft threads between the tread plates 12. The coverage angle of the tissue-forming drum is approximately 1200. At one of the ends of the tissue-forming drum 5, there is a block 16dl for preparing and laying weft threads. In this case, any system for laying weft yarns can be used: shuttles, microchips, rigid rapiers, or a jet of liquid. The means 3 for moving the main threads 4 along the ridges is composed. from several, in particular, four rods 17, placed parallel to the direction of laying weft threads. The rods 17 are set in motion in the direction of the double arrow from the actuator 18. The rods 17 are equipped with guide eyes for the main threads 4. The number of rods 17 is selected depending on the nature of the interlacing, when there is only two interlacing webs, there are enough rods x, respectively, the number of rods increases. The actuator 18 is similar in design to the helix carriages of conventional weaving machines, however, it has the following advantages as compared to the latter: the weight of the rod 17 is much less than the weight of the remise, so that its movement requires much less energy; the size of the rod 17 is significantly smaller than the dimensions of the shaft, so that a much larger number of rods can be placed on the same space; the amount of movement of the main yarns, and consequently of the rods, is much smaller than the stroke of the remise, since this movement should not be consistent with the parameters of the shed, but only ensure the transition of the main yarn from one gap between the spacer plates to another. Thus, the movement of the rod 17 can be done in a significantly shorter period of time than the movement of the remise, and the frequency of movement of the rods can be several times the frequency of the reciprocating movement of the remise, which at the present time limits the speed capabilities of high-performance flat-weaving looms. The fabric-forming drum of the machine (Fig. 4-6) is made in the form of a pipe 20 connected to the drive shaft 19 with the grooves 21 and 22 directed along its forming to install the lamellar ridges 10 and 11, the grooves 21 and 22 have an L-shaped cross section, transverse grooves of sections of different grooves 21 and 22 are directed in different directions. The number of grooves of each type is fourteen. With such a construction of a tissue-forming drum, it is possible to dispense with special shedding elements 15 for the lower branch of the main threads. In this case, the role of these elements is borne by the surface of the pipe 20. The spacer plates 23, which slightly project above the surface of the pipe 20, can play the role of shedding elements 15 for the lower branch of the main threads 4. Each shedding element 14 (Fig. 6) for the upper the branches of the main threads 4 are made in the form of a hook, bent in the direction following the shedding element 14, along the rotation of the cloth-forming drum 20, the surfboard 12. The upper portion of each separating plate 13 is made in the form e parallelogram, the lower side of which corresponds in shape to the inner edge of the hook. Thus, the shedding elements 14 for the upper branch of the main yarns and the separation plates 13 form with the surface of the pipe 20 and the surfacing plates 12 a channel 24 for inserting the weft yarn. The upper part of the tread plates 12 has a crescent shape, with the tip of the sickle directed against the direction of rotation of the cloth-forming drum 20, and the outer edge is most radially protruding among the edges of the other plates and serves for the weft threads. The outer edge of the upper part of the separation plates 13 lies somewhat closer to the surface of the drum 20. The level is external-. The surface of the shedding elements 14 for the upper branch of the main threads 4 is somewhat closer to the surface of the drum 20 than half the distance between the surface of the drum 20 and the outer edge of the upper part of the surfacing plates 12. As can be seen from FIG. 6, the shape and size of the separating 13 and surfing 12 plates, as well as the mutual removal of the grooves 21 and 22 and lamellar ridges 10 and 11 are chosen so that between the lamellar ridges there is a small distance less than the thickness of the breaking 12 and separating 13 plates is equal, shedding the same elements 14 and 15 and the spacer plates 23 are made considerably thicker, preferably three times as thick as the surf plate 12.
    The individual elements of each lamellar ridge 10. and 11 are joined, for example, by gluing together in blocks of a length of, for example, 100 mm. The blocks during assembly of the machine are inserted into the corresponding grooves 21 and 22 and fixed. If it is necessary to change the thickness of the plates (in the present embodiment of the fabric-forming drum 20), only the plate-like ones are replaced; ridges 10 and And without dismantling the entire drum 20.
    Tissue-forming drum 20 can be mounted along freely rotating reed weaving looms with a wave-like movable across the main threads with a shed, i.e. from segmented plates with protrusions.
    According to the gas station, in each gap between the breaking plates 12 of the lamellar ridge 10 and between the dividing plates 13 of the ridge 11 there are two main yarns 4. In the gap between the dividing plates 13 there are two main yarns 4 of the lower or two yarns of the upper branch of the pharynx . In the interval between the surf plates 12, one main thread 4 is placed from the upper and one from the lower branch of the pharynx. Such a position of the main threads 4 corresponds to a weave with four rods 17. For greater consistency, FIG. 2 and 3, the number of main threads 4 and rods 17 is halved. In this case, every second gap between the surf plates 12 is empty. I.
    The machine works as follows.
    The warp threads 4, which enclose the tissue-forming drum 20, form, with the help of shedding elements 14 and 15, wavy throats, which during rotation of the drum 20 move along the main threads 4. A weft thread is laid in each of the throat using unit 1 to prepare and lay weft yarns which is nailed to the edge of the fabric of the chest area 6.
    In accordance with the flight program, before immersing the ridge 10 and 11 (FIG. 2) into the main threads 4, the actuator 18 moves the rods 1 to one of the two extreme positions. In the extreme position of the rods 17, the main threads 4 are pressed against the left or right breaker 12, or the separator 13 plate of the previous ridge 10 and 11. This makes it possible to reliably distribute the main threads 4 into the required gap between the plates of the subsequent lamellar greon.
    The process of distributing the main yarns 4 in the lamellar ridges 10 and 11 is carried out as follows (Fig. 3). Before entering the ridge 11 into the main yarns 4, the yarns are located in the ridges 11 and 10, and the yarns marked with one line are controlled from the rod 17 and form the lower shed branch in the area of the ridge 11, and the main yarns 4 controlled by the rod 17 marked with two lines, form in the zone of the ridge and the upper branch of the pharynx. If according to the program, the main threads 4, controlled by the rod 17, form a ridge and a lower branch in the zone, and the main threads 4, controlled by the rod 17, form the upper branch, then the rods 17 and 17 move the actuator 18 to the position corresponding to the position of the main threads 4, shown in solid lines; Otherwise, the rods 17 and 17 move in the direction corresponding to the arrows. In this case, the threads 4 occupy the position depicted by dotted lines. In both cases, the main threads 4 in these extreme positions are pressed against the surf plates 12, which ensures that the separator plates 13 enter between the main threads 4, dividing them according to the interlacing program, which in the area of the ridge 11 form the upper and lower branches of the pharynx.
    The use of the present invention will improve the reliability of the uniform distribution of the threads in the fabric and the reliability of reproduction of the interlaced programmed pattern.
