Definitions

  • the invention relates to a two-bed flat knitting machine with needles which are longitudinally displaceable in their needle beds and between the needles about a common longitudinal axis between a rear and a front position and which are controlled by lock parts of the carriage and which are in the stitch formation region with a projection, a stitch receiving throat formed below the projection and are provided with a curling edge.
  • strikers have the disadvantage that they are direction-dependent and therefore have to be switched over when the carriage is reversed. Different types of stripes are also required for different types of knitting, so that the strippers have to be replaced frequently. Further disadvantages are that a stripper always affects several stitches lying next to each other at the same time and that the strippers, which are generally made of wire, can easily bend, which favors thread snagging. Strippers also make it difficult to see into the comb gap and often collide with tongue opener brushes on flat knitting machines. For some patterns that require needle bed displacement, the strikers must even be turned off so that they cannot operate there at all.
  • the invention has for its object to design the sinkers of a two-bed flat knitting machine of the type mentioned in such a way that a retention of the stitches from the drive-out area of the needles is guaranteed without having to put up with disabilities or restrictions in normal knitting operation.
  • the wedge edge of the sinkers is formed in the knitting pull-off direction to and below the thread take-up throat and in that the sinkers of the two needle beds face each other and lie in their forward position with their projections spanning the ridge gap.
  • the sinkers behind and somewhat below the wedge edge can have a short circular slot which has a closed edge and through which a wire which forms the stitch wiping edge of the needle bed in question is passed.
  • the thread is placed over the sinkers below the projection of the sinkers which closes off the ridge gap. Slipped thread loops do not slip over the projections of the boards, which gives you a free hand when controlling the boards.
  • the stitches formed are exposed and are not enclosed by the sinkers, so that needle bed displacement and a transfer of stitches can take place without hindrance. It is no problem to start knitting with empty needles.
  • An adjustment movement of the sinkers in the direction of closing the comb gap during the last part of the withdrawal movement of the needles also makes it possible to compensate for a stitch length by means of the sinkers, as is the case when knitting with the needles of only one of the two needle beds, due to the wedge edge located underneath the sinker closure to maintain the same mesh length is desirable.
  • the needle beds continue to have their own tapping edge in the familiar shape of a wire.
  • the schematic representation of a knitting lock of the carriage, not shown, of the flat knitting machine in FIG. 1 shows a lock channel 20 for controlling the needles 21 of the front needle bed 22 or the needles 21.1 of the rear needle bed 23 (FIG. 2) of a flat knitting machine.
  • the needle control curve 20 is limited in a known manner by fixed lock parts 24, 25, 26, 27 and two trigger lock parts 28 and 29 which are adjustable in a known manner.
  • the knitted lock also has a lock channel 30 formed between lock parts 31 and 32 for the same-designed sinkers 33 of the front needle bed 22 or 33.1 of the rear needle bed 23, which protrude into the sinker track 30 with a control foot 34, 34.1.
  • FIG. 1 shows the knitted lock in a lock setting for the carriage direction indicated by an arrow 35.
  • the trigger lock parts 28, 29 are adjusted in opposite directions.
  • the blank lock parts 31, 32 are adjusted en bloc in the direction of the arrow 36 shown in FIG. 1, so that the blank lock track area 30.1 reaches the height of the trigger lock part 28.
  • FIG. 1 also shows a thread guide 37 which feeds a thread 38 to the needles 21 and / or 21.1 of the flat knitting machine in the area of the sinker web area 30.1.
  • the sinkers 33 have an opening for a pivot axis 39 or 39.1 (FIG. 2) common to all sinkers 33 of a needle bed 22 or 23, on which the stitch pattern projections 40 shown individually in FIG. 4 are also lined up are each arranged between the plates 33 in the needle beds 22 and 23.
  • the circuit board 33 also has a short, arc-shaped slot 41 with a closed edge, through which a wire 42 is held, which is held by the knitting protrusions 40 and forms the knitting edge of a needle bed.
  • the arcuate slot 41 limits the pivoting movement of the boards around the common axis 39 from a rear position shown in FIG. 3 in the direction of the arrow 43 shown in FIG.
  • the arcuate slot 41 is located behind a wedge edge 44 of the board, which adjoins a stitch-receiving throat 45, which in turn is formed in the knitting direction 53 indicated by an arrow below a projection 46 of the board 33.
  • FIG. 1 different lock positions II, V, VI, VII, VIII, XI are marked with dash-dotted vertical lines. 2, 5, 6, 7, 8 and 9 show the position of the sinkers 33 and 33.1 and the position of the needles 21 and 21.1 of the two needle beds 22 and 23 at these points in the production of a single-surface knitted fabric, if only that Needles 21 of the front needle bed 22 process a thread 38.
  • Fig. 2 shows that at the lock point II, the plates 33 of the front needle bed 22 and the plates 33.1 of the rear needle bed 23 are in their rear position, in which they do not protrude into the comb gap 50 of the flat knitting machine. An old stitch 47 hangs in the head of the needle 21.
  • Fig. 1 different lock positions II, V, VI, VII, VIII, XI are marked with dash-dotted vertical lines. 2, 5, 6, 7, 8 and 9 show the position of the sinkers 33 and 33.1 and the position of the needles 21 and 21.1 of the two needle beds 22 and 23 at these points in the production of a single-
  • FIG. 5 shows the position of the knitting tools at point V of the lock representation of Fig. 1, before the start of the needle drive.
  • the plates 33 and 33.1 of both needle beds 22 and 23 have been pivoted simultaneously in the direction of arrows 43 by the plate lock curve 30 into their front position, in which their projections 46 and 46.1 lie against one another.
  • the comb gap 50 is thus bridged by the plates 33 and 33.1, so that when the needles 21 of the front needle bed 22 are subsequently driven out into the position shown in FIG. 6, which they assume at position VI in FIG. 1, the old stitch 47 slips into the stitch receiving throat 45 of the associated board 33 and does not slide out of the Comb gap 50 can slide up. Only the boards 33.1 are controlled in the needle bed 23. The needles 21.1 remain at rest.
  • the sinkers 33 and 33.1 of both needle beds 22 and 23 are pivoted back into their rear position by the sinker track 30 during the transition to the sinker track section 30.1, as shown in FIG. 7 from the lock point VII and as indicated by the arrows 43 there.
  • the comb gap 50 of the flat knitting machine is free again and the thread 38 can be inserted by the thread guide 37 (FIG. 1) unhindered into the adjustment area of the needles 21 of the front needle bed 22.
  • the old stitch 47 hangs on the shaft of the needle 21 and bears against the wire forming the stitch wiping edge 42 of the front needle bed 22.
  • 11 to 17 show the same as Figs. 2 and 5 to 10 in the manufacture of a two-layer knitwear when the needles 21 of the front needle bed 22 and the needles 21.1 of the rear needle bed 23 together with the sinkers 33 and 33.1 in operation are.
  • FIG. 12 corresponds to FIG. 5 and thus the control relationships at the lock point V in FIG. 1.
  • Fig. 13 corresponds to Fig. 6 and thus the tax relationships at the lock point VI in Fig. 1st
  • Fig. 14 corresponds to Fig. VII and thus the tax relationships at the lock point VII in Fig. 1st
  • Fig. 15 corresponds to Fig. 8 and thus the tax relationships at the lock point VIII in Fig. 1st
  • FIG. 16 corresponds to FIG. 9 and thus the tax relationships at the lock point X of FIG. 1.
  • FIG. 17 corresponds to FIG. 10.
  • FIGS. 11 to 17 show the connecting thread arch 49 between the old stitches held by the needles 21 and 21.1 of the two needle beds.
  • FIG. 13 shows how when the needles 21 and 21.1 are driven out, the old stitches on this connecting arch 49 are retained by the plates 33 and 33.1 in their forward position.
  • FIG. 14 shows the inserted new thread 38, from which new stitches 51 and 52 on the two needle beds 22 and 23 are drawn in FIG. 16.
  • additional lengthening takes place for the length compensation of the new stitches 51 by means of the wedge edges 47 of the plates 33 and 33.1 which are moved into the comb gap 50.
