Description

Since the loops are wound and the weft is laid behind the backs of the needles, the warp threads are not controlled by anything from the guide elements to the loops and with local process disturbances in the boom can spontaneously shift relative to the desired position and when lifting the needles ki Such a spontaneous transition leads to defects in the web. A disruption in the process of a knight arises from one to three threads on the warp of knots, cones, bulges, which can be gripped by lowering needles and wound up. In addition, violations can occur as a result of the interaction of the warp threads with the moving loop-forming thread, which in the course of the yarn covers them from the inside of the web. Displacements of the warp threads can also occur when complex weaves with missed needles appear as a result of unbalanced lateral pressure from the loops on the warp threads, which limits the range of possible weaves. If the loop-forming yarn breaks and the loops are dropped, the warp threads that are not held by the loops are assembled into bundles. The ring-shaped comb of the known Maiya does not ensure the restoration of the predetermined position of the warp threads when they are displaced. Putting them in place must be done manually, which is associated with the time spent on manual labor and reduces the productivity of the machine. The famous circular grinding machine, which has radially movable guide plates for the base, is made at the end in the form of a SPZ tube. This machine can only be made of a low class due to the features of the power supply design for the base. Other disadvantages of the machine are the inaccessibility for the threading of the yarn feeders for piercing the looping thread of the detected base, as well as the limited view of weaves that can be worked out on it. Also known is a circular grain bus, which has radially movable lugs of an L-shaped C4. The same machine has the same drawbacks as the previous machine. Moreover, the high location of the ears relative to the needles does not ensure reliable laying of the foundations in the inter-needle gaps for the reasons stated above. Thus, the problem arises, to create such a circular die machine, the design of thread-bearing devices, which would ensure a reliable process in a draw, would not limit the class of the machine, would reduce the number of cartons of southern weaves with a different arrangement of the warp threads and weft relative to the loops, facilitate the process of maintenance machines, would reduce the number of manual operations. The purpose of the invention is to increase the reliability of the process in a range, facilitate maintenance and expand the technological capabilities of the machine. The goal is achieved by the fact that in a round-shaped machine for the manufacture of weft knitwear, the loops of which hold the main and weft threads containing a needle cylinder with vertically movable tongue needles, a platinum bed with radially movable platinum, which have forked nozzles forming a V-shaped mouth, needle and platinum locks, which form in the hall systems and serve to move the needles and platinum, respectively, during relative rotation of the cylinder and locks, the thread feeding system of the base, to torus is mounted above the needle cylinder annular comb for inserting warp yarns in mezhigolnye intervals, feed yarn looping system for inserting it under the needle hook, nitepoda- system. In order to lay the weft yarns behind the backs of the needles outside the annular comb, the annular comb has an outer conical surface on which grooves are made along the generators, carries movable cleats in the grooves made in the form of straight plates that have a hem in the middle, and at the end, protruding from the comb, the peephole for the warp thread is covered on the outside with locks forming channels that interact with the catholes and serve to drive the ears during relative rotation of the locks and the comb. The annular comb in the machine can be mounted with the possibility of movement relative to the needle cylinder in height and in the circumferential direction. The locks of the locks of the machine carvings in each system have areas that ensure that the eyelets are located at the level of the needle backs in their lower position, the area for moving the ears to the position in front of the needles when lifting needles, the area that ensures the arrangement of the eyelets in front of the needles in their upper position, as well as areas for moving eyelets behind the backs of the needles when they are moved to the lower position. Structurally, lug locks can be made in the form of separate blocks, having an outer conical surface and connected to a ring that is installed with the possibility of circumferential movement with respect to needle and platinum locks. In addition, the thread-forming system of the loop-forming threads of the machine may contain yarn drivers located in different sleeping systems in the sleeping systems or inside the ring-shaped comb, and the yarn feeders located outside the comb have the top of the scientific research institute contour that interacts with the warp threads and is located below the movement path. heads of tongues IG.G. Such an implementation of the mini-mines allows controlling the positioning of the warp threads relative to the loop-forming organs (needles and plates), as well as thread feeders of loop-forming and weft itey in the process of knitting. The use of a conical comb with straight, movable lugs moved with the help of locks allows to locate the eyes of the gaps, into which the warp threads are threaded, most expediently in the process of diving. In the phases of the knitting process, when the needles are located in the lower position and the location of the warp threads is not controlled by the needles, the proposed machine implementation makes it possible to significantly reduce the uncontrolled length of warp threads and more accurately guide them to the inter needle areas, using also platinum, equipped with forked v-shaped spout. In addition, it provides the most favorable conditions for laying the yarn threads behind the backs of the needles, excluding duck emissions over the nozzles, since it allows you to position the warp threads vertically at the level of the backs of the needles during the duck laying. In the phases of the looping process, when the needles are in the upper position, the tabs are located outside the needle cylinder and are moved upwards from the extraction plane. This makes it convenient to position the yarn feeders both from inside the comb to lay the loop forming yarn under the edges of the needles from the inside of the warp crown, and outside the comb to lay the loop forming yarns under the hooks of the needles outside the base using a yarn feeder, the upper contour of which interacts with the warp threads and is located below needle trajectories. Alternating the thread guides outside and inside the comb in different systems allows to significantly expand the number of possible weaves that are cut by a machine with a different arrangement of the stitches of the loops relative to the main threads. The proposed machine design allows movement of the tabs from the axis of the machine and upwards from the extraction plane when the needles are lifted, which means that the exact direction of the warp threads in the inter-needle gaps, if due to process disturbances in the undercuts (passing the knots, breaking the loop-forming thread, etc.) P.) the warp threads shifted from the desired position, i.e. the machine becomes self-priming. The self-replenishing of the warp threads into the inter-needle gaps, in addition to increasing the reliability of the knitting process, allows complex interlacing with needle selection, as it compensates for the unbalanced pressure of the loops on the warp threads in interlacing with missed needles (jacquard, lined, etc.). Making the outer surface of the conical locks in the form of a cone makes it possible to make room for convenient maintenance of the zone in the undercarriage and ease of refilling the yarn feeders of the loop-forming and weft threads. In addition, the proposed design increases the ease of maintenance of the machine and eliminates the manual operations of filling the main threads in the needle needle spaces, which reduces the time spent on maintenance and, therefore, increases the actual performance of the machine. The described machine can be structurally made with a fixed or rotating needle cylinder. When the cylinder is stationary, rotary wheel needle and platinum locks, a thread-forming system of loop-forming and weft threads, are made. The threading system of the base and the ring-shaped comb are fixed, the locks of the comb rotate synchronously with the locks of the needles and platinum. When the needle cylinder is rotating, the machine has fixed needle and platinum locks, a thread-forming system for loop-forming and weft threads; The threading system of the main threads and the comb are made rotating synchronously with the needle cylinder, the locks of the comb are fixed. FIG. 1 shows a machine with a rotating needle cylinder, general view; in fig. 2 - needle center-ring and ring-shaped comb in the intake system, where the yarn feeder of the loop-forming thread is located inside the comb, a partial section; in FIG. 3, a zonal system, where the yarn feeder of the loop-forming thread is located outside the comb, a partial section; in fig. 4 shows a yarn feeder for feeding the loop forming yarn outside the comb in FIG. 5 is a scan of the locks of the comb in FIG. 6 - the simplest interlacing of the basic weft knit, for the formation of which the yarn feeders of the looping yarn are used, which are located only inside the comb; in fig. 7 and 8 are examples of weaving basic knitwear with the use of looper and thread looper thread outside and inside the comb; FIGS. 9 and 10 are the frontal and horizontal projections of the combined paths of the loop-forming organs and the location of the yarn feeders for the interlacing of FIGS. 6; FIGS. 11 - 17 of the phase of the process in the yarn of the weave of FIG. 6; FIG. 18 and 19 — frontal and horizontal projections of the combined trajectories of the loop-forming organs and the location of the yarn feeders for the underlay according to FIG. 7; FIGS. 20-30 are phases in the undercover of FIG. 7,

The proposed round grating machine has a core 1 (FIG.), In one of the racks 2 of which the drive 3 of the machine is mounted. The frame contains a table on which the mechanisms / s of the pulling 5 and the winding 6 of the blade 7 are mounted, which is guided into the stretching mechanism by the spreader 8,

On the upper table 9 of the core 1, three pillars 10 are mounted, supporting table 11, on which the basis threading system 12 of the warp and the stationary system 13 of the thread-forming loop-forming and weft threads are mounted.

Base threading system 12 is mounted on a ring-shaped gear and holds four sections 14 with devices to bring them

the movement and the device 15 for guiding the warp threads into the zone in the stand, secured on the uprights 16.

The thread-forming and weft-thread yarn system 13 comprises a spool 17, having two zones for placing bobbins, thread guides 18 and thread watchers 19, which serve to guide the yarns into the zone in the under and outside of the warp. In the outer area 20 of the spool core 17, reels 21 are placed for feeding the yarns to yarns placed inside the warp. In the inner area 22 there are reels 23 for feeding the yarns to yarns placed outside the warp.

On the upper table 9 of the cage 1, the mechanism 24 is also mounted in the boom, which contains a rotating needle cylinder 25 (FIG. 2) carrying vertically movable tongue needles 26 in its grooves, the heels of the latter interacting with fixed locks 27 surrounding the needle cylinder 25ji Under the needles 26 in the slots of the cylinder 25 are placed the pushers 28, which serve for selective lifting

The needles 26 and interacting with the locks 29, also covering the needle cylinder 25, Locks 27, providing one cycle of moving the needle up and down, form one into the filling system. By car around the needle cylinder can be placed several in the hall systems, the number of which depends on the class and diameter of the cylinder. For example, for small class 10 with a cylinder diameter of 650 mm, you can place 26 in the hall systems

A platinum ring 30 is attached to the needle cylinder 25, in the radial grooves of which there are radially movable platinum 31 and 31a. Two platinum are placed in each groove, the tips of which are separated and form a V-shaped shed for the warp thread. Ptki platinum 31 and 31a interact with platinum locks 32, mounted on a ring 33, which is mounted on brackets 34, covering fixed racks 10. On platinum locks 32 weft yarn thread 35, feeding weft threads 36 outside the base 37 under the nozzles of platinum 31 and 31a for inserting the weft yarn behind the backs of the needles 26,

On the platinum locks 32, the yarn feeder 38 can also be strengthened (FIG. For feeding the loop-forming yarn 39 under the hooks of the needles 26 outside the base 37. The thread carrier 38 (FIG. 4) has an upper contour 40 that interacts with the base yarns 37 and is located below the path of the heads zychkovyh needles 26, Thread guide 35 and 38 can alternate in adjacent in the hall systems.

Above the needle cylinder 25 there is mounted an annular comb 41 (FIG. 2), having an outer conical surface on which grooves are made along the generators. In the grooves of the comb 41, there are arbors 42, made in the form of straight plates, which have, at the end protruding from the comb 41, an eye 43 for the warp and hem 44, cooperating with locks 45, the latter have an inner conical surface that encloses the outer conical the surface of the comb 41, Last attached to the intermediate ring 46 with the possibility of circumferential movement relative to it. The ring 46 is fixed by means of adjusting screws 47 on the uprights 16, through which it is possible to change the height of the ring 46, and with it the comb 41, relative to the needle cylinder 25. This design allows the comb 41 with the earholes 42 to be set to the required position relative to the needle cylinder height and in the circumferential direction so that the lugs 42 are split in the middle of the inter-needle projection at a given height relative to the platinum 31 and 31a. A ring 48 is also fixed on the ring 46, in which there are holes for directing the warp yarns 37.5.

A suit 49 is fixed inside the comb 41, on which the yarn feeders 50 are mounted to lay the loop forming yarn 51 under the hooks of the needles 26. The disk 49 is mounted on a JQ spindle 52 (FIG, which is attached to the spool 17. The yarn guides 50 and weft feeds 35 are mounted in one room. The thread guides 38, underlaying the loop-forming thread 39 underneath the base, and the thread guide 5D, the positioning loop-forming thread from the inside of the base, can alternate in adjacent rooms.

Locks 45 lugs 42 are attached to blocks 53, the number of which is equal to the number in the hall systems of the machine. The blocks 53 have an outer conical surface, thereby facilitating access to the zone in the yoke, freeing up space for installing the weft yarn feeder 35 or yarn feeder 38 for the loop-forming thread, facilitating their dressing.

The blocks 53 are fixed on the ring 54 mounted with the possibility of displacement in height and in the circumferential direction on the brackets 55 which clasp the pillars 10. Such a design allows to establish the necessary clearance between the locks 45 and the comb 41.35 a. also shift the paths of the tabs 42 relative to the path of the needles 26 in order to provide them with the necessary interaction in the process of the fabric.

Locks 45, mounted on blocks 40 53, each in a gate system consist of two wedges 56 and 57 Fig. 5, between which a channel 58 is formed. for a current of 44 lugs 42; The channel 58 has a section 59, which provides the location of the eyes 43 of the lugs 42 at the level of the backs of the needles 26. At the same time, due to the lugs' arrangement 42 c. conical comb 41, eyes occupy the lowest position. The needles 26 are also in this lower position at this point.

The portion 60 of the channel 58 serves to move the tabs 42 to a position in front of the needles. The needles are also raised to the top position. S5

Section 61 of channel 58 provides the location of the eyes 43 of the lugs 42 in front of the needles. Due to the conical surface of the comb 41, the eyes 43 of the artifacts 42 are in the up-60 position. The needles are also in the upper position. In the region 61, the lugs are in the zone where the yarn feeder is located. 50 for looping 5

forming yarn 51 from the inside of the warp. Or the yarn feeder 38 for laying the loop-forming thread 39 outside the warp. Thread guides 50 and 38 may alternate in adjacent systems.

A portion 62 of channel 58 serves to move the tabs from the front and top position to the rear and bottom (initial position. The needles are also lowered at this time.

On the described machine, it is possible to produce knit knitwear, the loops of which hold the warp and weft threads, various weaves.

FIG. Figure 6 shows the interlacing of a smooth basic weft knit, in which the weft yarns 36 are located between the cores of the loops 63 and the yarns of the warp 37, which, in turn, are covered by the stitches of the loops 64, with the loops formed of the thread 51.

FIG. Figure 7 shows an interlacing in which the loops 65 are formed from yarn 39, the weft 36 is located between the cores of the loops 65 and the yarns of the warp 37. The warp threads are covered with the inside of the outline 66, which also encompasses the stitches 65 and are formed from the yarn 51.

Fig. 8 shows an interlacing in which the loops, warp threads and weft are arranged similarly to the weave of Fig. 6, but selectively some loops hold the sketches 67 formed from the yarn 39, and the stretches 68 between the sketches are arranged similarly to weft yarns between the skeletons and thread basics.

The proposed machine works as follows.

. From the actuator 3, the rotation is transmitted to the needle cylinder 25, the pulling mechanisms 5 and the winding 6, the base threading system 12, and with it the comb 41. In the process, the blade 7 is straightened by the spreader 8, pulled by the pulling mechanism 5 and is wound into a roll by a winding mechanism 6.

To form the web, the warp threads 37 are wound up from the sections 14 on the side and with the tabs 42 tabs. are in the inter-needle gaps. The loop-forming yarns 39 or 51. are unwound from the reels 22 or 21 and, with the help of yarn feeders 38 and 50, are directed under the hooks of the needles 26.

The weft yarns 36 are wound from bobbins, 22 and the yarn feeder 35 are guided through the spikes of the needles by platinum 31 and 31a.

When the needle cylinder 2 rotates, the needles 26 and the pushers 28, by moving the fixed locks 27 and 29, move vertically. Platinum 31 and 3 under the influence of locks 32 moved in the radial direction. When the combs 41 rotate by the action of the locks 45, the caps 42 move at an angle to the needles 26 and the platinum 31 and 31a. To form a web, the interlacing of which corresponds to the fig in all loop-forming systems, sets yarn feeders 50 for looping yarn 51 and yarn drivers 35 for weft yarns 36. Yarn feeders 38 are not used. In order to carry out the process, the needle heads .26 move along the path 69 (FIG. 97, the necks of the plates 31, 31a move along the path 70 (FIG. 10), and the eyelets 43 of the ears 42 move relative to the needles and platinum, so that on the frontal projection (FIG. 9, the lower edge of the peephole 43 outlines the trajectory 71, and on the horizontal projection (FIG. I, the inner edge of the peephole 43 outlines the trajectory 72. In the initial position (AA, FIG. 9 and iO) the head of the needle 26 (FIG. 11) located at the level of the extraction plane, formed by the chins of platinum 31 and 31a, which are retracted from the axis of the machine to the extreme The anterior position of the Arrows 42 is located in the lower position, defined by the section 59 of the channel 58 of the locks 45, and the distance of the heads 43 to the extraction plane formed by the chins of the platinum 31 and 31a is the smallest, the warp threads 37 are arranged vertically (FIG. 11J, the weft thread 36 is located below the nozzles of the platinum 31 and 31a. When moving to the next position (BB Fig. 9 and 10, the needles 26 and the ears 42 stand and the platinum 31. And 31a move to the axis of the machine so that the neck of the platinum is occupied La posterior position at the level of the back of the needle 26 (Figs 12 and 13). In this movement, the nozzles of the platinum 31 and 31a (Fig. 13) seize the weft thread 36 and the plant behind the backs of the needle 26. At the same time, the V-shaped opening of the double platinum nozzle captures the vertical threads of the warp 37 and directs them to the middle of the inter needle gap. The vertical arrangement of the warp threads facilitates the process of inserting the weft yarn behind the needle backs and reduces the likelihood of it being ejected over the platinum nozzles if the process goes down (knot passing, sharp fluctuations in the tension of the weft yarn). . If due to the passage of knots on the warp threads, breakage of loop-forming threads, etc. when the process fails, the Ornov 37 is shifted by an amount less than half of the needle pitch, then the V-shaped jaw of the nozzles of the platinum 31 and 31a, seizing it, sets it in place. The short distance between the eyelet 43 of the bristle 42 and the chin of the platinum 31 and 31a (for example, 5 mm) significantly increases the reliability of this process. When moving to the next position (B-B in Figures 9 and 10), the platinum 31 and 31a stand and the needles 26 move upwards. At the same time, the tabs 44 of the tabs 42 move along the section 60 of the tabs 45, which cause the eyes 43 to move upward from the cutting plane and move away from the axis of the machine due to the conical surface of the comb 41. The mutual movement of the tabs 42 and the needles 26 is such that their paths do not intersect. When the needles 26 and tabs 42 move from position B-B to position B-B (Figures 9 and 10), the warp threads 37 are moved between the needles 26 to the front side of the needles. If a malfunction in the knight (passage of a knot on the warp, filling and reloading the warp, breaking of the loop-forming thread with loops from the needles) is lost, the warp of the warp has shifted from a predetermined position to the next needle needle gap (i.e. more than 3/4 needle pitch). ) and the previous movement of the plates did not restore the position of the base, then when the needles 26 and tabs 42 are moving together, the threads of the base 37 are twisted around the backs of the lifting needles and set to the desired position (Fig. 14). The joint movement of needles and tabs provides self-refilling of the warp threads in the inter-needle gaps. Upon further movement of the looping organs, the raised needles 26 are prevented from moving the warp 37, which are located in the inter-needle spaces. In the next stage of the process, the tabs (YYD of Figures 9 and 10) are arranged in an anterior and an upper position, making room for the yarn feeder 50 of the loop-forming yarn 51. The needles 26 rise up, completing the conclusion at which the loop 63 comes off the tip of the open tab on the needle core. Platinum stand in the rear position, keeping the loop 63 from lifting and the warp threads 37 in the inter-needle gaps. In the GG position (Fig. 15), the yarn feeder 50 runs a loop-forming thread 51 under the hooks of the raised needles 26. The yarn guide 50 is placed inside the ring-shaped comb 41 and is located between the recessed ears 42 and the needles 26 inside the rim of the base 37. On the section - DG trajectories 9 and 10, the needles 26 move downward, gripping the loop-forming thread 5 to form loops 63. The platinum moves away from the axis of the machine, freeing up space to form new loops. The sinks 42 stand in the forward position. In the D-D position FIG. 16 n the latins 31 and 31a move away from the axis of the machine to the extreme position, the needles 26, moving downward, capture the loop-forming yarn 51, the old loops 63 close the needle tongue. Ports 44 of the ears 42 begin to move along the section 62 of the channel .58 of the locks 45. The eyelet 43 of the groove 44 thereby moves down to the axis of the machine.In the section DE, the trajectories of the loop-forming organs (Fig.9 and 10) of platinum 31 and 31a are kept in the forward position, the needles 26 continue to move downwards and the loop-forming thread 51 , bend it first on the warp threads 37, and then on the chins of the base atin. The old loops are knocked off from the needles and through them looping of the thread is formed to form new loops. The warp threads 37 are covered with the inside of the loop through the loops and hold the weft thread 36, which, after the old loops are dropped, turns out between the loops 63 and the warp threads 37. Thanks to the weft thread 36, the warp threads 37 are also earned in the Ushkovinnn canvas 42 are moved down and to the wasps of the machine, occupying the rearmost extreme. position {initial). In position E – E (Fig. 17, platinum 31 and 31a are located in the posterior position, the ears 42 are in the lower position, the heads of the needles 26 are below the extraction plane formed by the chin of the platinum. The warp threads 37 are located vertically at the level of the backs of the needles. Between the eyelet 43 of the lug 42 and the nose of the platinum 31 and 31a, the exit hole of the wearer of the driver 35 is located, with the help of which the weft thread 36 is guided under the nozzles of the platinum for subsequent laying of the warp threads behind the back of the needle. EA (Fig.9 and 10) PL Tines and lugs 42 stand in the initial position, and the needles 26 rise upwards until the extraction plane is reached from the head. In this area, weft 36 is laid. In this process, the formation of one loop stitch is completed, the next loop-forming system repeats Thus, when weaving the interlacing according to FIG. 6, it can be seen that the use of a conical comb with eyelets set in motion by means of locks provides an increase in the reliability of the undercover process, which consists in eliminating arbitrary transition warp yarns in adjacent mezhigolnye intervals and to increase the reliability of insertion of the weft yarns. The described work of the lugs provides self-refilling of the warp threads in the inter-needle gaps. For the undercoat of the web, the interlacing of which corresponds to Fig. 7, the machine must have an even number of loop-forming systems, and in odd-numbered systems, yarn feeders 38 are installed for looping the threads 39, which are fed outside the base. In even-numbered systems, yarn feeders 50 are installed to feed the loop-forming yarn 51 from the inside of the warp and yarn feeders 35 to lay the weft yarn 36 outside the warp behind the backs of the needles. In order to carry out the process, platinum 31, 31a and tabs 42 (figs. 18 and 19 move along the same trajectories 70, 71, and 72 as in the intersection of fig. 6). Needles 26 in odd systems move along normal trajectory 69, and in even systems using a pusher 28, the trajectory of all the needles is changed so that after the pre-ascent all the needles remain at a height sufficient to catch the looping yarn with hooks, but not enough for the loops to descend from the open tongue to the needle core (trajectory 69a , Fig. 18). The process in an interest swells in the following way: In the initial position in odd systems (Ж-Ж FIGS. 18-20), the heads of the needles 26 are at the level of the extraction plane, under the hooks of the needles-26 there are loops 65 and sketches 66. Platinum 31 and 31a are in the anterior position, under the nozzles of the platinum, is the weft thread 36. The consoles 42 are located in the rear and lower position, the warp threads 37 are thereby positioned in an upright position; When moving to the next position (and-AND FIGS. 18,19 and 21) needles 26 and the lugs 42 stand and the platinum 31 and 31a are moved to the rear position, capturing This thread 36, the plant behind the backs of the needles 26. The V-shaped mouth of the nozzles of the platinum 31 and 31a seizes the warp of the base 37, directing it to the inter-needle gaps. Then the needles 26 move upwards, and the ears 42, moving at an angle to the needles, move up and to the front position (K-K, Figs 18.19 and 22). The warp threads 37 while plant mc between

needles and bend in the upper contour 40 of the yarn feeder 38. Upon further raising of the needles 26, loop 65. and the sketch 66 descends from the end of the tongue onto the needle shaft. In the L-L position (Figs. 18, 19 and 23), the exit hole of the yarn feeder 38 guides the loop-forming thread 39 under the hooks of the needles 26. The upper loop 40 of the yarn feeder 38 bends around the warp threads 37, and the thread 39 is fed under the hooks of the needles outside the warp. The needles 26 begin to fall, the platinum 31 and 31a move away from the axis of the machine, moving to the front position and making room for new loops. The warp threads 37 (MW Figs 18,19 and 24) are dropped from the upper contour 40 of the yarn feeder 38, but the loop-forming yarns 39 are under the hook of the descending needle 26, which is blocked by a tongue closed by the loop 65 and the outline 66. The arches 42 move to back lower position.

The needles 26, descending below the extraction plane formed by the chins of the platinum 31 and 31a (H — H, Figs. 18, 19 and 25), thread the thread 39 to form a new loop 65, onto which the old loop and draft 66 are dropped. loops are formed on the front of base 37. The loop-forming organs return to. initial position.

In the next (even system of plates 31 and 31a, moving to the axis of the machine, the old loop 65 is retracted and the sketch 66 is behind the backs of the needles and, capturing with the V-shaped nozzles of the warp 37, directs it to the inter-needle gap ( P, Fig.18, 19 and 26;

The needles 26 are raised up, the loop 65 opens the needle tongue (P-P j of Figures 18,19 and 27. The hollows 42 move to the front upper position, directing the warp 37 to the needle needles of the raised needles and freeing up space for the yarn feeder 50 of the loop-forming thread 51 .

The needles 26 are raised to a height sufficient to open the tongue and to grip the new loop-forming thread, but so that the loop 65 does not descend from the tip of the tongue to the needle shaft, i.e. the needles move along trajectory 69a (Fig. 18).

Between the raised needles 26 and the tabs 42, which are located in the front position, a yarn feeder 50 C-C is installed, Figs 18.19 and 28J, which directs the looping thread 51 under the hooks of the needles. The warp threads 37 are folded over by the lower edge of the yarn feeder 50, which is facilitated by laying 1U of the thread 51 under the needle hooks.

BaTeivT needles drop down, grasping thread 51, platinum 31 and 31a

retract to the front position, freeing up space for making sketches (T-T, Figures 18,19 and 29; HiiTb 51 is bent first on the warp threads 37 from the inside, and

then on platinum chins. The tongues of the needles 26 are not closed, since the loop did not fall on the needle core. Therefore, from yarn 51 instead of pe-. An outline 66 is formed, covering the base 37 from the inside.

The warp yarns 37 are made to be woven between the stitches of the loops 65 and the stitches of the sketches 66. After the drafts 66 are formed, the weft yarns 36 also turn out to be earned in the web between the yarns of the warp 37 and the cores of the loops 65.

When the needles 26 and the ears 42 are in the lower position FF, FIG. 18, 19 and 30), between the nozzles of the platinum and the ears of the outside of the base 37 there is an outlet of the yarn feeder 35 of the weft yarn 36, which is guided under the nozzles of the platinum 31 and 31a for subsequent insertion behind the needles. The loop-forming organs return to their original position.

In this process, the weaving of the weave of FIG. 7 ends. In the following loop-forming systems, the described process is underlined. This knitting process may have options for a different order of needle selection. 26

using pushers 28 even in hall systems. The resulting weaves have an increased filling capacity with fibrous material with comparative looseness and mobility.

structures, due to the presence of sketches 66. If only part of the needles form sketches in even-numbered systems, then on the seamy side of the web there will be increased stretches that can create patterned effects.

For the weave canvas of FIG. 8, the machine must also have an even number of systems. In odd

the systems are installed by the floaters 38 for feeding the loop-forming yarns 39 outside the base 37, and the needles 26 are selected by means of the pushers 28 so that some of them pass by in the hall system, not participating in the knowledge, and the part rises to a height sufficient to catch the thread, but not enough to move the loop to the needle shaft below the tip of the tongue, i.e. a portion of the needles in a certain order moves along the path 69 a (Fig. 18).

Claims (4)

In even-numbered systems, yarn feeders 50 are installed to lay the threads 51 and form loops therefrom. The needles 26 in the even-numbered systems move along the usual trajectory 69. Platinum 31 and 31a and the lugs 42 and π are stirred along the usual trajectories 70-72 m, as for the previous weaves. In odd-numbered systems, the needles 26 pick up the thread 39 supplied by the thread guide 38 outside the base and form the outline 67 (Fig. 8). At the place of idle needles, elongated broaches & 8 are formed, which, with platinum 31 and 31a, are placed on the backs of the needles 26, rising in even-numbered systems. Thus, the stretches are located in the canvas, as well as the yarn threads, between the cores of the loops and the threads of the base 37, i.e. The wires are fixed to the warp threads and do not sag on the inside. In even-numbered systems, the process of knitting proceeds as well as in the case of the interlacing of FIG. 6. The overflow according to FIG. 8 may have options that conclude in the order of selection of needles in odd systems. The weave of FIG. 8 has an increased vertical structure of the structure and has a reduced tendency to slide along the weft, since the sketches 67, covering stretches and loops, interfere with this. Thus, the use of the proposed machine provides an increase in the reliability of the knitting process, facilitating the maintenance and expansion of its technological capabilities. Invention 1.
