Definitions

  • the invention relates to a slide needle for knitting machines, with a needle base with a needle hook and at least one needle foot, a slider mounted in the needle base with a slide foot and a swivel part articulated on the needle base behind the needle hook.
  • a needle is known from DE-C3-151 150.
  • DE-C3-3 702 019 discloses a latch needle for high-speed flat knitting machines, the needle tongue of which completely closes the needle head can be pivoted into a partially open intermediate position by an associated spring element.
  • the invention has for its object to provide a slide needle of the type described above, which ensures a safe and flawless separation of the newly laid thread from the old stitch and enables a reduction in the necessary expulsion paths of the slide needle in the formation of a stitch.
  • the object is achieved according to the invention by a spring arranged in the needle base body, which holds the pivoting part in a position protruding from the needle base body.
  • the swivel part can be attached very close to the needle hook, as a result of which the drive-out paths of the slide needle can be considerably reduced when the stitch is formed.
  • the old stitch is safely separated from the new thread. It slides very much easily over the swivel part, which in turn is swung up immediately after release from the stitch by the action of the spring.
  • a safe and flawless separation of the newly laid thread from the old stitch is also ensured in the first needle after the carriage reversal, if the invention is used in flat knitting machines and / or oscillating circular knitting machines.
  • the pivoting part can be pivoted away from the needle hook against the action of the spring. In this way, the stitch can easily slide out of the needle hook when the pusher needle is driven out.
  • pivoting part essentially disappears into the base needle body when pivoting away from the needle hook. In this way the movement of the stitch is made even easier. This makes it possible to form a small stitch and to perform knitting that is gentle on the stitch.
  • the pivoting part is essentially triangular. This results in particular advantages for shifting the stitch on the needle and for holding the stitch after the shift to the other, rear side of the swivel part.
  • the swivel part has a first side edge facing the needle hook, which, when the swivel part is in a protruding position, has a sliding surface which rises from the needle hook and protrudes from the needle base body.
  • the increasing sliding surface of the side edge facing the needle hook results in a uniform movement of the stitch on the swivel part, so that it continuously counteracts the spring force the spring can be depressed and slide behind the swivel part.
  • the pivoting part preferably has a second side edge facing away from the needle hook, which is essentially perpendicular to the longitudinal axis of the slide needle when the pivoting body is in the protruding position.
  • the base body has a stop which limits the pivoting movement of the pivoting part in a first end position towards the needle hook. In this way, a defined position of the swivel part is ensured if no pressure is exerted on it or on the spring interacting with it.
  • the sliding surface is thus defined in its position and its sliding angle.
  • a further advantageous embodiment of the invention consists in that the slide essentially covers the swivel part when the slide is in a sliding position directed towards the needle hook. This ensures that the stitch is properly and safely stripped from the needle.
  • the spring is advantageously an elongated spring element.
  • the spring element is preferably arranged behind the swivel part in the needle body and the free end of the spring element is in contact with a nose at the lower end of the second Side edge of the swivel part. This results in a particularly compact, small design of the slide needle.
  • the swivel part expediently has a rounding in the region of the intersection of its two side edges, as a result of which the unimpeded and rapid swiveling up of the swivel part is promoted and facilitated without influencing or obstructing the stitch hanging on the slide needle.
  • the swivel angle between the two end positions of the swivel part is advantageously less than 45 °, which has a positive effect on the working speed of the knitting machine.
  • the needle base body expediently has a run-up slope in the region of the swivel part, through which the slide can be raised in such a way that its back covers the swivel part in the sliding position closing the needle hook.
  • Fig. 1 shows the front part of a slide needle for knitting machines with a needle body 1 with needle hook 2 and with a slider 3 mounted in the needle body 1 in the basic position.
  • a short, essentially triangular swivel part 4 is behind the Needle hook 1 is pivoted about an axis 5.
  • the swivel part 4 has a first, front side edge 6 and a second side edge 7. In the area of the intersection of the two side edges 6 and 7, a rounding 8 is provided.
  • a nose 9 is provided, on which the free end of a spring 10 engages.
  • the spring 10 in the form of an elongated spring element or a leaf spring is fastened in the needle base body 1 and pivots the swivel part 4 into an upright position against a stop 11 in the needle base body 1.
  • the first side edge 6 of the swivel part 4 forms a sliding slope for a stitch on the slide needle, whereby the pivoting part 4 is pivotable against the action of the spring 10 in the needle body 1.
  • the second side edge 7 of the swivel part 4 is in the swiveled-up position almost perpendicular to the longitudinal axis of the slide needle.
  • the pivot angle of the pivot part 4 between its two end positions is preferably less than 45 °.
  • the needle body 1 has in the region of the swivel part 4 a run-up slope 12 through which the slide 3 can be raised in such a way that its back covers the short swivel part 4 in the sliding position closing the needle hook 2.
  • the swivel part 4 is formed by the side edge 6 sliding stitch 13 pivoted into the needle body 1 (Fig. 2).
  • the pivoting part 4 offers no further resistance apart from the minimal force of the spring 10, so that the stitch 13 slides easily backwards. Therefore, the stitch 13 can surely slide over the swivel part 4 even when the needle is driven out small.
  • the swivel part 4 swivels immediately into the basic position by the force of the spring 10 (FIG. 3). This, in turn, has the advantage that the distance between the swivel part 4 and the needle hook 2 can be kept very small and the needle output is thus even shorter.
  • the slide 3 Before the needle is withdrawn, the slide 3 is pushed towards the needle hook 2 (Fig. 4). The slide 3 slides onto the ramp 12 of the needle body 1 so that it covers the pivoting part 4 and the needle hook 2 in its foremost position (FIG. 5).
  • the design of the slide needle described enables, on the one hand, minimal expulsion paths during stitch formation and, on the other hand, a secure separation of the old stitch from the newly laid thread. In the case of flat knitting machines or oscillating circular knitting machines, this is ensured in particular also with the first needle after the carriage reversal.
