Definitions

  • ABSTRACT A device for linking U-shaped borders produced by a straight knitting machine to the edge of a fabric in a straight linking machine.
  • the device includes a first stationary comb for receiving stitches on the end edge of the border and a second comb movable between a plurality of positions for transfering these stitches from the stationary comb to the edge of the fabric.
  • this invention relates to an improved device for linking tubular or U-shaped borders, adapted to be used in cooperation with straight knitting machines and straight linking machines for knitted garments and to a related operating method.
  • the device according to the present invention permits to appreciably speed up and to make semiautomatic the linking operation of the two edges of a tubular border with the end portion of a knitted fabric to be finished.
  • the mechanical device according to this invention conveniently used in cooperation with straight knitting machines and linking machines permits to link in one single operation all stitches constituting each of the two edges of the border.
  • the aforementioned device is used when the end stitches, namely the last ones formed and conveyed onto the needles at one side of the needle bed of a straight knitting machine have been previously collected on the teeth of a straight comb.
  • the device according to this invention mainly comprises two straight combs fixedly secured on two pairs of clamps one of which is stationary and the other one is movable, and means to change the mutual position of said combs according to predetermined patterns by the displacement of the movable clamps.
  • FIGS. 1,2 and 3 show a straight comb for collecting the stitches, i.e.: FIG. 1 represents a side view of the comb;
  • FIG. 2 a top view
  • FIG. 3 a perspective view of the comb
  • FIGS. 4 and 5 represent the instant device in a side view and a vertical section, respectively;
  • FIGS. 6, 7, 8 and 9 show the various transfer phases of the stitches of the second edge of'the tubular border from the first to the second comb;
  • FIGS. 10, I1 and 12 represent the various insertion phases of the edge of the garment to be finished between the two edges of the tubular border with simultaneous transfer of the stitches of the second edge of the tubular border onto the second comb;
  • FIG. 13 shows finallythe second comb which, after being removed from thev transfer tool, is mounted onto a. straight linking machine, for firmly connecting the stitches of the border to the intermediate edge of the garment to be finished.
  • the tubular border I is transferred from a straight or U-shaped knitting machine, on which it has been formed, onto the teeth 2 of a straight comb 3 which could be termed as a storage comb and which may carry also more than one border to be used in subsequent operations.
  • the comb 3 on the teeth 2 of which there are inserted the end stitches of the edges 1 and l", is fastened at its reference holes 3' on a stationary clamp or support member 4 (see FIG. 4 and subsequent Figures), provided with a baseplate 5.
  • Said pins 8 and 9 when following compulsory runs, determined by the shape of the grooves 6' and 6", respectively, will cause the upper ends 7 of the movable clamps or support members 7 to carry out predetermined movements, which will be consequently also effected by the second comb l0, releasably secured by suitable connecting or clamping means on said ends 7'.
  • This second movable comb 10 is designed to collect, due to operations which will be described later on, the two edges 1', 1" of the tubular border between which the edge of the garment piece to be finished is to be inserted.
  • the device according to the present invention is completed by a U-shaped bar 11, terminating in two forks 12, connected to the movable clamps 7 and maintained in position (FIGS. 4 and 5) by the springs 13 and the stops 14, said bar being arranged for movement rel ative to the baseplate 5.
  • the rod 15, which is to be longitudinally introduced underneath the teeth 2 of the storage comb between the two edges of the border to separate the same from each other (FIGS. 4, 7, 8, 9 and 10), and it can also be used to cause the stitches of each of such edges of the border to slide from the comb 3 to the comb 10 (FIG. 11).
  • suitable clamping knobs 16 adapted to fix the movable clamps in a predetermined position, during the transfer operations of the stitches of the two edges 1 and 1" of the'border from the comb 3 to the comb 10.
  • FIG. 6 there is shown the travel of the pins 8 and 9 along the grooves 6', 6" during a full cycle,v i.e.:
  • the point A indicates the initial position, shown more in detail in FIG. 7, namely with both combs 3 and [0 installed on the transfer device according to this invention, the pins 9 of the movable clamps 7 being still hinged in the forks 12, whereas the knobs 16 are released, since the clamps are actuated by the operator; the rod 15 is inserted in the tubular border carried by the comb 3.
  • the point B indicates the transfer position, subsequent to the first displacement of the pins along the grooves (FIGS. 8 and 9), the clamps 7 are being pushed forward by disconnecting their pins 9 from the forks 12 connected'to the bar II thus bringing the teeth of the comb 10 opposite the teeth of the comb 3 (FIG. 8).
  • the operator locks the clamps 7 by means of the knobs 16 and by grasping the ends of the rod 15 projecting laterally of the border Ion the comb 3 transfers the stitches of the first edge 1' from the teeth of the comb 3 to those of the comb l0.
  • the position C better shownin FIG. 10, represents the moment when the intermediate edge 17 is inserted. 3 V
  • the operator displaces the clamps 7 and locks them in the position shown (by means of the knobs 16 not shown in FIG. 10), the rod thus maintains the stitches of the edge 1"of the border 1 on the teeth of the comb 3, while the stitches of the other edge 1 are maintained on the teeth of the comb 10 due to the position thereof.
  • the operator is ina position to insert by hand and also withoutlooking at the job the edge of the knitwork 17 to be finished on the teeth of the comb 10.
  • the position D is shown in detail in FIG. 11 and corresponds to position B; by repeating the operations described at point 2, the operator moves the rod 15 off the border and with the aid of it he shifts the stitches of the edge 1" of the border from comb 3 onto the teeth of the comb 10.
  • the position E shows the movable clamps outlined at position A (illustrated in FIG. 7), but now the border 1 and the intermediate edge 17 are mounted in linking position on the comb 10 (FIG. 12).
  • the operator takes the comb 10 out of the clamps 7 and mounts it on the straight linking machine as shown in FIG. 13. More specifically, the comb 10, carrying on its teeth the border 1 and the intermediate edge 17, is mounted on the carriage 18 of a straight linking machine of known type, where by means of the pinion 19 it receives a translatory motion, adapted to bring, teeth by teeth, all stitches of the border 1, individually inserted over the teeth of the comb 10, in front of the needle 20, which, in cooperation with the crochet-needle 21, carries out the chainstitch linking the border 1 with the intermediate edge 17.
