Definitions

  • the invention relates to a slide needle with the Features of the preamble of claim 1 or Claim 2.
  • Slider needles such as those for flat knitting machines or Circular knitting machines have a needle body with a slide channel in which a slide is slidably mounted. At the free end of the needle body a needle head is designed in the form of a hook, which are opened or closed by the slide can.
  • the knitting machine has at least one flat or a cylindrical and or a plate-shaped needle bed on, formed in each of several needle channels are.
  • the slider needles are in these needle channels arranged longitudinally displaceable, being during the Knitting a reciprocating in the longitudinal direction Carry out movement.
  • the slide must be matched to this be moved back and forth.
  • the slide points to this a so-called foot, which acts as a means of transmission serves and engages with curved surfaces.
  • curved surfaces are the edges of one so-called castle channel.
  • both the head and the slide of the slide needle is in contact with the yarn, whereby depending on the nature and carried dirt load dust or filament deposits on the yarn Slider can occur.
  • dust particles adhering to the wool, from salt crystals, sand or short ones from woolen laundry Filaments are deposited on the slider. Through the back and forth movement of the slide can do this Particles get into the gate valve, causing difficulties can lead.
  • Such a slide needle is known from US Pat. No. 1,673,634 known with divided slide.
  • the slider is through two interconnected slide springs formed the each side over the hook of the slide needle push, causing them to spread out.
  • the arrangement of the slide needle is similar DE 44 30 705 A1. Again, the slider formed by two slide springs, which are located on the side of the Spread the hook over, creating dirt deposits between the slide springs can get.
  • the slide needle has a needle body with needle channel that guides a slide.
  • the slider is formed by a slide body, on which two mutually symmetrical trained slide springs are.
  • the slide springs are operated by the Periodically spreading the needle head, leaving dirt and fiber residues in the defined between the slide springs Gap can reach.
  • This slide needle has one in two mutually symmetrical slide springs divided slide on which is closed on three sides Slider channel of the slider needle arranged is. To guide the slider, it has an elongated hole provided by a guide pin is penetrated.
  • the slide channel is also open laterally, that At least one of the channel side walls is called an opening or has recess. Alternatively or additionally you can one or more openings in the bottom of the slide channel be provided. The side opening can be through a cutout can be formed in the slide channel wall.
  • This principle is also the slide needle according to claim 2 based. Leave recesses in the slide springs first to that accumulated between the slide springs Deposits from between the slide springs formed gap to the slide channel walls and through their Open openings to the outside.
  • the slide needle according to the invention proves is therefore less susceptible to contamination.
  • the slide springs have recesses have at different points in the two slide springs are arranged.
  • the cutouts create recording rooms and passages for in the Dirt channel got dirt and also prevent jamming the dirt between the slide springs. This also applies in part if the recesses are opposite each other are arranged overlapping areas. The overlap The cutouts minimize areas between the Slider springs, in which dirt and the could spread slide springs.
  • slide springs can also be between the guide sections and a respective mesh support section be asymmetrical what here too a reduced tendency to accumulate dirt and tendency to jam.
  • the slide springs are thus largely free of overlaps.
  • a slide needle 1 is illustrated in FIG. 1, to which a needle body 2, a slide 3, consisting of two slide springs 22, 23 and a slide body 21 belong.
  • the needle body 2 is for insertion into the needle channel provided a knitting machine and has a elongated needle shaft 4 on at its free end carries a hook 5.
  • the needle shaft 4 extends away from the hook 5 in a straight longitudinal direction.

  • the channel side walls 8, 9 are flat, plate-shaped structures that are parallel at a distance protrude towards each other from the needle body 2. You point starting from a slot start 11, initially an increasing one Height up.
  • the channel side walls 8, 9 are related to the longitudinal direction of the needle body 2 starting from the hook 5 at least so long that the side walls during the practical Use of the slide needle 1 is not complete move out of a needle channel. This gives the Needle 1 at least part of their leadership.
  • the needle body 2 Following on from the channel side walls 8, 9 Area is the needle body 2 with an elongated Cutout 15 provided with respect to the longitudinal direction on one side through the channel side walls 8, 9 and another side delimited by a projection 16 becomes.
  • the cutout 15 forms an area in which the Slider channel 7 is open. Instead of section 15 can also be provided side or bottom openings his.
  • the slide 3 has a slide body 21 (FIG. 4) and two slide springs 22, 23 on the slide body 21 are held. It is essentially through an elongated body with a rectangular cross section, on which one or more feet 24 are formed. These protrude at right angles from the slide body 21 and serve to drive it. In operation they intervene the lock channel of a lock and are used by this moved relative to the needle body 2.
