Definitions

  • the present invention relates to a method and an apparatus for transferring stitches on a knitting machine by means of transfer elements.
  • the known methods have the disadvantage that a large one Needle shoot is necessary.
  • the necessary control curves require correspondingly wide knitted locks.
  • the wide needle output leads to a reduction in production speed of the knitted piece.
  • the main disadvantage of the known methods is that that the stitches are passed to an adjacent needle or pulled a shoulder finger far out of the mesh and spread, making it sensitive Yarns can burst.
  • the slung Stitches are also enlarged by the transfer process, what is visible in plain knitted fabrics in the overall knitted picture and thus restricting the quality of the knitted piece.
  • the present invention is based on the object To propose methods and a device for transferring stitches, that a higher yarn load and an increase avoiding the production times of the knitted fabric.
  • the task is done using a stitch transfer method solved on a knitting machine by means of transfer elements, whereby all needles from which stitches are to be transferred a transfer element is assigned, which is characterized is that the loop stitch to be held in the needle passes through Needle ejection and retraction movements on the needle tongue or for slide needles placed on the closed needle slide and then the transfer element into the mesh inserted and the needle is pulled out of the stitch, so that the stitch hangs alone on the transfer element and to Transfer to the same or a different needle or to a needle other transfer element is available.
  • the stitch can be driven by a needle and subsequent needle retraction movement on the closed Tongue of the needle. It is sufficient that the The needle is only advanced so far that the stitch is behind the tongue is open. The stitch can also pass through a needle advance movement on the open tongue of the needle to be placed. Both when open and when closed Tongue the mesh is stretched enough to the transfer element to be able to pierce the mesh.
  • the stitch can pass through a needle advance movement with the slide open and one subsequent needle retraction movement with the slide closed placed over the closed slide. Result it then similar conditions for the transfer process as when placing the stitch on the closed tongue one Latch needle.
  • the method according to the invention can be used both on flat knitting machines as well as on circular knitting machines.
  • the inventive device for transferring stitches a knitting machine according to a method according to the invention for all needles from which stitches are to be transferred has an associated transfer element characterized in that the transfer elements one of at least have a leaf spring formed tip. With this leaf spring tip it is possible in the on the tongue or the Insert slider to keep the stitch under tension. The leaf spring plunges into the thread space of the needle and drives between the legs of the stitch.
  • the transfer elements have a tip formed by two leaf springs, one leaf spring over the left side and the other Leaf spring over the right side of the needle tongue or the needle slide slidable and insertable between the mesh legs is.
  • the tip will the stitch is captured symmetrically to the left and right of the needle shaft, whereby the transfer of the stitch onto the transfer element becomes even safer. After withdrawing the needle from the The two leaf spring elements spring out of the stitch together and together form the tip of the transfer element.
  • a hanging device for a flat knitting machine can the transfer elements in at least one over the arranged at least one needle bed of the flat knitting machine Barre be slidably mounted lengthways.
  • the be grooved at least one bar in which the Transfer elements are mounted to be longitudinally displaceable the Transfer elements have the same mutual distance like the needles of the at least one needle bed. This is ensures that each needle has a transfer element exactly is assigned.
  • the least a bar slidably mounted on the knitting machine his. This means that the stitches are laterally displaced the transfer process possible.
  • the bars with the transfer elements can also be fixed be arranged.
  • each needle bed of the flat knitting machine Barre with transfer elements is provided.
  • the bar can provided with transfer elements over their entire length be or only in sections. Besides, it is of course possible, several bars for each needle bed to be provided in those areas in which transfer processes should be made.
  • the transfer elements can preferably be similar to the needles the flat knitting machine can be controlled by control curves be in the projections arranged on the transfer elements intervention. It is useful if these control curves on the carriage or carriages for needle control of the flat knitting machine are arranged. Then it is not a separate one Drive required for the selection of the transfer elements.
  • Fig. La shows the front needle bed 1 and the rear needle bed 2 a flat knitting machine.
  • Switch needles 3 and switch needles in the rear needle bed 2 as well 4 slidably mounted lengthways.
  • Bed over the needle 1 and 2 with the needles 3 and 4 are transfer elements 5 and 6 for Transfer of stitches arranged.
  • the needle 3 holds a stitch 7 in its thread space 33 which of Needle hook 31 and the closed needle tongue 32 are formed becomes.
  • the transfer element 5 assigned to the needle 3 is part a stitch transfer device 150, which is not shown here is shown.
  • the transfer element 5 has a tip 51 with a chest surface 53.
  • the Needle 3 in its home position, i.e. H. the stitch 7 lies through the effect of the knitted fabric deduction in the direction of arrow 71 on Tee off 11 of the front needle bed 1.
  • the needle 3 is driven out in the direction of the arrow 300 so that the needle tongue 32 passes through the stitch 7 has been opened and the stitch 7 is now on the needle shaft is located behind the open tongue 32.
  • the transfer element 5 can temporarily not take part in the knitting process Stitch transfer element 5 withdrawn in the direction of arrow 501 so that the stitch 7 still hangs on the tip 51, but the tip 51 is behind the central axis 100 of the knitting machine located.
  • the transfer element 5 can laterally be displaced by a half pitch over the needle 3, so that the needle 3 can continue to participate in the knitting process, without the stitch on the transfer element 5 7 hampers the knitting process (Fig. Lf).
  • the stitch transfer element 5 is in the direction of Arrow 500 in its transfer position for needles 3 of the same Needle bed 1 has been driven.
  • the needle 3 is in the direction of arrow 300 is advanced until the needle hook 31 in the stitch transfer element 5 is immersed in the area 52 and itself thus located in the area of the tip 51.
  • the needle hook 31 slides through the legs of the stitch 7 through it.
  • the stitch transfer element is then 5 fully retracted in the direction of arrow 501, so that the stitch 7 now hangs on the needle 3.
  • the needle 3 moves again in the direction of the arrow 301 Basic position so that the stitch 7 hangs in the needle hook 31 and abuts the tee 11 (Fig. 2c).
  • the transfer element 6 is assigned, participate in the further knitting process, but the stitch 7 on the transfer element 6 for some time can be held, so the needles 4 and the transfer element 6 are offset by half a division, so that the stitch 7 releases the expulsion space of the needle 4.
  • Fig. 5 illustrates the takeover of the stitch 7 from a pusher needle 30.
  • the slide 35 of the needle 30 and thus also the Thread space 36 are closed.
  • the needle 30 has been in so far Arrow direction 331 is withdrawn so that it is in the transfer position is located, d. H. the stitch 7 lies on the closed Slider 35 on.
  • the transfer element 5 was in the direction of the arrow 500 advanced so far that its tip 51 in the Thread space 36 and thus punctures between the legs of the stitch 7.
  • FIG. 6 shows a further variant of taking over a stitch 7 through the stitch transfer element 5 for latch needles 3.
  • the needle 3 is in the direction of arrow 300 in its stitch transfer position propelled in the stitch 7 now the open tongue 32 comes to rest. In this position too the stitch 7 is stretched. It also imagines Free space between the open tongue spoon 32 and the needle shaft.
  • the transfer element 5 is in this free space Arrow direction 500 has been driven with its tip 51. The tip 51 now sticks between the legs of the Stitch 7 and can take over the stitch.
  • FIG. 7a, 7b and 8 illustrate a preferred embodiment a transfer element 5.
  • Fig. 7a shows the side view and FIG. 7b the top view of the transfer element 5.
  • 7b illustrates that the tip 51 of the transfer element 5 actually a double point made of two leaf spring elements 51 and 51 '. The leaf spring elements lie at the top 51 and 51 'together.
  • the transfer element 5 also has a solid shaft 54 which longitudinally displaceable in a groove of a not shown Be guided and controlled by a control curve can.
  • FIG. 8 illustrates the takeover in a perspective representation the stitch 7 from the needle 3 through the transfer element 5.
