Definitions

  • the invention relates to a flat knitting machine with a lanyard and with stripping and / or stitch hold-down elements, such as those e.g. is known from DE-A-2 707 637.
  • the knitted fabric pull-off devices conventionally arranged below the needle beds in flat knitting machines have variously proven to be disadvantageous.
  • uneven draw-off tensions result in the knitted fabric, if not all knitted areas can be grasped by the take-off elements at the same time.
  • Disadvantages also arise in the case of knitted fabrics with patterns due to different stitch formation, if, for example, heap accumulations occur, or also in the case of knitting methods for forming spikes in the knitted fabric.
  • Strip-in and / or mesh hold-down elements are to be understood as elements, for example, from GB-PS 844 186, 10 53 477, GB-OS 21 20 684, DE-GM 80 19 179, DE-OS 30 13 145, 34 23 564 and 34 28 059 can be seen.
  • the invention has for its object to ensure in these flat knitting machines provided with stripping and / or stitch retaining elements for holding down stitches in the comb gap area that despite the lower stitch tensions present, safe processing of the thread and treatment of the stitches by the knitting tools remains ensured even with high-speed machine.
  • the object is achieved in a flat knitting machine of the type mentioned according to the invention in that it is provided with latch needles, the tongue of which, in a manner known per se, has two stable positions in its swiveling range, one of which is before the full closed position and the other before the full Open position of the tongue and from which the tongue can be pressed against the restoring force of a spring in the full closed position or the full open position.
  • the needle tongue advantageously resting with its tongue end near the joint on a rod-shaped spring inserted into the tongue guide slot of the needle shaft and with its ends resting on the ends of the tongue guide slot and that The end of the tongue has two flattenings which determine the two stable positions, is a safe interplay between mesh heads even in the case of high-speed machines and also when setting large mesh lengths and handle heads and the latch needles even in the absence of the tension exerted by a pull-off device on the stitches formed.
  • the sinkers of the two needle beds facing each other and lying in a front position with the formation of bridges with projections spanning the comb gap, that no old stitch can move up from the comb gap along the shafts of the expelling needles.
  • the sinkers form the stitch hold-down elements, whereby the knitting machine can additionally be provided with a stripper.
  • the tongue needle 21 shown in FIG. 1 has an inserted spring rod 11 in its tongue slot 10, which extends over the needle opening 12 and is supported with its ends on the needle shaft 13.
  • the tongue 14 of the tongue needle 21 lies with its end near the tongue axis 15 against the spring rod 11 and is provided with two flats 16 and 17 at this end. These flattenings result in two stable positions for the tongue 14 within its swivel range, from which it can only be moved by bending the spring rod 11.
  • the tongue 14 is shown in one of these stable positions, in which the flat 16 rests on the spring rod 11, with a solid line. In this stable position, a gap 18 remains between the tongue spoon 19 and the needle head 20.
  • the full closed position of the tongue 14, in which the tongue spoon 19 lies against the tip of the needle head 20 and which is shown in FIG. 1 with a thin dash-dotted line, can be achieved against the restoring force of the spring rod 11 by pressure on the tongue spoon 19, such as is exerted by a stitch when knocking off.
  • the tongue 14 forms a relatively wide gap 18 ⁇ with the needle shaft 13.
  • This second stable position is shown in FIG. 1 with a thick dash-dotted line.
  • the full open position of the latch needle 21, in which the latch 14 bears against the end of the latch slot 10, is indicated by a thin dash-dotted line.
  • the tongue can be in this full end position 14 press against the restoring force of the spring rod 11 by means of a stitch sliding over the tongue onto the needle shaft.
  • FIG. 2 to 7 show a schematic cross section through the comb gap area 30 of a V-bed flat knitting machine with a front needle bed 22 and a rear needle bed 23, which with needles 21 and 21.1 of the type shown in FIG. 1 and with sinkers 33 and 33.1 are busy.
  • the sinkers 33 or 33.1 of the front needle bed 22 or of the rear needle bed 23 are each lined up on a common pivot axis 24 or 25 together with stitch pattern projections 26 and 27.
  • Each circuit board also has an arcuate slot 28 or 28.1 designated in FIG. 3, through which a wire 29 or 29.1 which forms the stitch wiping edge of the relevant needle bed 22 or 23 is guided.
  • the arcuate slot 28, 28.1 limits the pivoting movement of the boards 33, 33.1 about the pivot axes 24 or 25.
  • Each board is provided with a projection 31 or 31.1, and the projections of two opposing boards 33 and 33.1 can abut against each other according to FIG. 3 brought so that they form a bridge spanning the comb gap 30.
  • FIG. 2 shows a relative position of the needles 21, 21.1, in which an old stitch hangs in the heads of the needles 21 and 21.1, which are connected to one another via a connecting thread arch 49.
  • the tongues 14 and 14.1 of the needles 21 and 21.1 are in their stable partially open position, in which, according to FIG. 1, the flattened portion 17 of the tongue 14 rests on the spring rod 11.
  • Fig. 3 shows the position of the knitting tools before the start of the needle drive.
  • the plates 33 and 33.1 of both needle beds 22 and 23 are pivoted into their front position, in which their projections 31 and 31.1 lie against each other, so that when the needles 21 or 21.1 are subsequently driven out into the position shown in FIG. 4, the position held by the respective needle old stitch cannot slide up from the comb gap 30.
  • the old stitches 48 and 48.1 have slipped over the tongues 14, 14.1 onto the needle shaft, whereupon the tongues 14 and 14.1 spring back into their stable, partially open position.
  • FIG. 6 shows the take-off position in which the old stitches 48 and 48.1 slide over the closed needle head and thereby press the needle tongues into their full closed position.
  • Fig. 8 shows a transfer position of the knitting tools, in which the needle 21.1 takes the position of the transferring needle and the needle 21 the position of the receiving needle.
  • the stitch 55 in the throat of the transferring needle 21.1 or on the needle hook of the taking over needle 21, which is spread by the needle spring 56, is caused by the raising of the needle 21 in the direction of arrow II with certainty that it is in the raised position needle tongue 14.
  • Fig. 9 shows the dropping of the stitch 55 in the transfer process.
  • the stitch 55 in the needle hook of the needle 21 and at the same time on the needle shaft of the needle 21.1 causes the needle tongue 14.1 to pass underneath the movement of the needle 21.1 in the direction of the arrow III and thereby close it, in order to subsequently slide over the needle hook.
