Socks and the following process to remove tights from the device.
    A seamless stocking that can be closed from the toe using the proposed device (STI. Fig. 1) consists of a leg part 1 of the stocking, a ribbed part 2 containing rubber threads, and a toe part 3 attached to one end 1 of the line 4 of the joint. FIG. 2 shows a sock-closure seamless stocking. Line 4 of the compound is a straight line.
    After deforming the joint line 4 towards the leg, the stocking is stitched along a straight line 5 defined along both endpoints of the joint line 4, the edge of the cut of the closed toe part 3 is parallel to the straight line, then the stocking is released to its original condition the At the moment of release of the deformation, the line 4 of the compound is restored to its original direct state in connection with the good repair ability of the material.
    After stretching the stocking in the transverse direction (Fig. 3), the joint lines 4 give a straight shape through the use of guide fingers 7 and 8, which have points 9 and 10 protruding outward on the upper part, which are located at the end points of the joint line 4. The device comprises holders 12 mounted on the frame 11, on which the suction pipes 13 are fixedly mounted. The longitudinal axes of the holders 12 are arranged perpendicular to the direction of movement of the stocking. Each holder 12 has a pair
    the guide pins 7 and 8 mounted for rotation on the sides in front of the first sliding element 14 on the axles 15. The front parts of the guide pins 7 and 8 can slide into the two guide slots 16 of the supporting element 17 with the possibility of sliding. 7 and 8 by one ends are connected with a device for their breeding and moving, made in the form of a circular plate 18 mounted on the back of the sliding
    About item 19.
    When rotated by a quarter turn plate 18, the front parts of the fingers 7 and 8 are located in the open position (Fig. B). If the plate 18 is rotated in the opposite direction, the front portions of the guide fingers 7 and 8 return to the ready position, as shown in FIG. 7. Between the frame 11 and the needle machine 20 of the sewing machine, there is a device for fixing a part of the stocking, which has an endless conveying element including a chain drive shaft 21 with the front: and rear valuable wheels 22 and 23 and a driven shaft 24 with similar wheels 25 and 26. Through pairs of sprockets 22 and 25, as well as 23 and 26, endless chains 27 and 28 are in engagement with them.
    A plurality of equally spaced drive elements 29 are mounted on an endless chain 27, with one drive protrusion 30 projecting from holder 12 in order to
    0, the protrusion 30 pushes the drive element 29. With the water element 29, it moves on the chain 27 at the same speed and in the same direction as the holder 12.
    On the endless chain 28 is set
    5 is the same number of equally spaced pin holders 31 (Figs. 14 and 15) as the drive members 29 (see Fig. 13). The guide pin 32 is held vertically on the pin holder 31 (see Fig. 14). The upper part of the pin 32 is directed vertically, but also extends in the plane of the endless chain 28. The pin 32 is slidably supported inside the hole of the pin holder 31. The normal position of the pin 3 relative to the CG holder is maintained by installing between them and the spring 33 so that the length of the part the pin 32, protruding from the holder 31, remains on; standing by If some pressure is applied to pin 32, it can slide down inside the hole of the pin holder 31. A straight guide 34 with a groove for moving the pins 32 in it is installed above the holders 12. The sliding element 19 (Fig. 8) is mounted the cam roller 35 is rotatably rotatable. The cam plate 36 is provided with three cam surfaces 37, 38 and 39, which come into contact with the roller 35 of the pusher.
    Corresponding to the right-side movement of the holder 12 (see Fig. 13), the cam roller 35 comes into contact with the cam surface 37, which acts on the block, pushing it forward along the suction pipe 13 against the spring force of the spring 40. When the cam roller 35 comes In contact with the cam surface 38, the relative position of the block and the suction pipe 13 becomes as shown in FIG. 11. When the cam roller 35 comes into contact with the cam surface 39, this arrangement becomes as shown in FIG. 12. Consequently, said cam roller 35 remains in contact with said cam surface 39 for such a time that it takes to close the toe and complete the stitching of the toe part 3. When the cam roller 35 comes into contact with the midpoint of the cam surface 38, and the drive The protrusion 30 on the holder 12 comes into contact with one of the drive elements 29 of the infinite RPI 27, the guide pin 32 is located in the vertical plane containing the axis of the shaft 21 (Fig. 13).
    When the guide pin 32 is pushed up to a point located on the center line of the stocking when interacting with the rectilinear guide 34, the pin 32 keeps the middle part of the stocking from pulling forward, although both lateral parts of the middle of the stocking can be moved forward with respect to the forward movement of the block ( Fig. 11).
    After advancing the block, the stocking is shaped as shown in FIG. 12 and maintain it from the moment when the cam roller 35 comes into contact with the left end of the cam surface 39 (see FIG. 13) until the moment when the cam rod 35 reaches the right end of the cam surface 39. When the holders 12 together with seamless the stockings run along the straight line of the frame 11 and move across to the central line of the stocking, it is stitched (see Fig. 5). As the holder 12 progresses further and the cam p | Olika 35 moves out of contact with the cam surface 39, the pin 32 disengages from the stocking, as it is already in its inclined position on the endless chain 28 (see Fig. 13). As the block advances further from the needle mechanism of the sewing machine under the action of the spring 40, the seamless stocking is closed on the suction pipe 13.
    The sock-closed edge 6 seamlessly engages with the front edge of the support element 17, whereby the closed seamless stocking is prepared and pulled inside the suction pipe 13. After 1 straight line 5 of stitching is made on the deformed toe part Zi of the closed-toe 3 release stocking from the device get a seamless stocking with a closed sock edge of the arcuate shape (see Fig. 2).
    FIG. 19 shows a variant of using the pin 32 mounted in the support member 41 of the holder, 12 so that the upper part of the pin 32 can engage with the groove of the rectilinear guide 34, and the spring 42 is installed so that the upper part of the pin 32 is specified in the supporting element 41. The lower part of the pin 32 has a head 43. Below the guide pins 7 and 8 and the straight guide 34 there is a guide plate, 44 parallel to the straight guide 34. When the head 43 comes into contact with the upper surface of the straight pin 32, pin 32 is pushed upward, overcoming spring 42 and maintained in this state all the time while pin 32 slides along the surface of guide plate 44 during lateral movement of holder 12. In this case, the upper part of pin 32 protrudes upward from surface the guide pins 7 and 8 and engages with the groove of the rectilinear guide 34. When the holder 12 (Fig. 18) runs along the frame 11, the suction tube assembly 13 and the guide pins 7 and 8, the seamless stocking and the pin 32 move together sideways along the way linear guide 34. With this lateral movement, similar to the movement in FIG. 13, it is possible to stitch the straight line 5 of the stitching (FIG. 2)
    FIG. 20, ten individual holders 12 are shown located along an oval passage that is made on frame 11. Holders 12 are connected by chain links 45, forming one endless target. On the frame I, the main drive shaft 46 and the driven shaft 47 are rotatably mounted on both axes of the oval passage. Two driving drums 48 are fixedly mounted on the driving shaft 46, and two driven guide drums 49 on the driven shaft 47 are pushed or pushed holders 1-2. By means of a sprocket 50 mounted on a drive shaft 46 and a driven sprocket 51 mounted on the driven shaft 47, the pivoting movement of the drive shaft 46 is transmitted to the driven shaft 47 via an endless chain 52.
    A pair of drive drums 48 has a plurality of serrated grooves located along its peripheral surface. Each holder 12 also has a protrusion 53, which engages with the serrated groove 54 so that the holder 12 can be pushed using a pair of driving drums 48. Therefore,
    The case shown in FIG. 20, the three holders 12 are pushed so that they pass along the oval aisle, when the drum 48 rotates with the drive shaft 46, supporting the engagement of the three projections 53 with the three toothed grooves 54, respectively. Each of the ten symbols 1, II, III, IV, V, VI, VII, VIII, IX, X shows a certain position of one of the holders 12. When one of the holders 12 moves from position I to position I, the operator captures the rim portion 2 seamless stocking and holds it toes, part 3 in front of the suction pipe 13 of the holding block. Then a seamless stocking is sucked inside the suction pipe 13, after which the ribbed part 2 is placed over the free end part of the support element 17 of the holding block. The part of the stocking that does not cover the holding unit is automatically pulled out from the inside of the suction pipe 13, and the seamless stocking is turned inside out. In this case, it is necessary to keep the toe part 3 of the powerless stocking from being put on the holding unit. When one of the holders 12 is moved from position II to position III, a pair of guide pins 7 and 8 are moved apart so as to stretch the nose part in the transverse direction. Then, the guide fingers 7 and 8, together with the seamless stocking, move the needles of the sewing machine towards the mechanism 20. After the forward movement is completed, the guide pin 32 engages with the stocking, so that one point of the stocking is pushed upwards with the pin 32. When one of the holders 12 is moved from position III to position IV, the guide fingers 7 and 8 move further towards mechanism 20 the needles of the sewing machine until the line on the toe part 3 of the stocking, on which it is necessary to stitch it, enters the stitching position of the needle mechanism of the sewing machine 20. During lateral movement of the guide pins 7 and 8 together with the stocking, as well as during operation needles seam The yarn machine 20 receives a stitching line 5 on the toe part 3. When one of the holders 12 moves from position IV to position V, the guide fingers 7 and 8 move away from the mechanism 20. Needles of a sewing mask and are pulled into the inside of the suction pipe 13. When moving o) i, Horo from the holders 12 from the position V to the position VI, the ribbed part 2 of the seamless stocking is put on the suction pipe 13, and from the position VI to the position VII - the toe part 3 of the seamless stocking is sucked inside the suction pipe 13, and then part of the closed seamless stocking left on hold block, for turning it from the inside out to the face, after which, as shown in position VIII-X,

    The tights can be simultaneously placed on two adjacent suction pipes 13 so that when two adjacent holders 12 move from position II to position III or from position I to position II, respectively, the operator clamps the connecting part of the stocking of tights 55 and holds their stockings in front of the suction pipes 13 Then, the tights parts 56 and 57 are sucked inside two adjacent suction pipes 13, respectively, by means of suction pipes 58 and 59. After that, the connecting part of the tights 55 is put on over both adjacent free end pieces Steps support element 17 adjacent retaining blocks. A part of the tights, worn on the support blocks, is automatically put on over the outer surface of the suction pipe 13 with the help of two pairs of stitches in the rollers 60 (see Fig. 21). Thus, the parts 56 and 57 of the pantyhose 55 are turned inside out. In this case, it is necessary to keep the socks of the tights from putting them on the holding blocks. When one of the holders 12 is moved from position II to position III, while the other of the holders 12 is moved from position I to position II, the pair of guide rollers 7 and 8 of the first holder 12 are moved apart in order to stretch the toe in the transverse direction the part of the pantyhose into which a pair of guide pins 7 and 8 are inserted. Then, the guide pins 7 and 8, together with the parts 56 and 57 of the pantyhose 55, move the needles of the sewing machine towards the mechanism 20. After the forward movement is completed, the guide pin 32 engages with the pantyhose, so that one point of the pantyhose is pushed upwards with the pin 32. When the second holder 12 is moved FROM position 1 in position II and the first from position II to position III, the pair does not move the guide pins 7 and 8 of the second holder. However, when the second holder is moved from position II to HI, part 57 of the pantyhose is captured by another pin 32. Consequently, part 56 is followed with some delay by part 57 while maintaining the same operating conditions, therefore, the sequence of operations is described only FOR part 56. When the first holder 12 is moved from position III to position IV, the guide fingers 7 and 8 are moving forward towards the needle mechanism 20 of the sewing machine until the line on the toe part 3 of said part 56, by which it can be stitched Not suited to the position of the needle stitching unit 20 of the sewing machine. When the guide fingers 7 and 8 are transversely moved along with the tights, and also when the mechanism 20 of the needle of the sewing machine is operating, a stitching line 5 on the toe part 3 of part 56 and a cutting line 6 are obtained. When the first holder 12 is moved from position IV to position V, the fingers 7 and 8 move from the mechanism 20 of the needle of the sewing machine and they are also pulled into the inside of the suction pipe 13. When the first and second holders 12 pass through positions VII and VIII, the toe parts 56 and 57 of the tights are closed to the inside of the suction pipes 13 pneumatic with loi via the suction pipe 61 and 62 (see. Fig. 21). Then, some parts of parts 56 and 57 remaining on the retaining blocks are sucked inside the suction pipes 13 so that they are turned out from the inside out with the help of two pairs of pipes in the rollers 63 back to their original sides. When the first and second holders 12 pass through positions IX and X, respectively, the toe-covered portions 56 and 57, turned on the right side, are simultaneously withdrawn from the suction pipes 13 so that the tights 55 can be pneumatically transported to the post-processing station with using the suction pipe 64. If both parts 56 and 57 of the pantyhose 55 need to be closed with the toe in the same way, then two adjacent suction pipes 13 can be used, mounted on the same holder 12. Claim 1.
