Definitions

  • the invention relates to a device of the type mentioned in the preamble of claim 1.
  • a device of the type mentioned in the preamble of claim 1. it is known, in particular in weft knitting machines, also in galon crochet machines, to arrange perforated needles in the form of so-called segments, each of these segments in a carrier made of metal or plastic a group of Contains perforated needles, which are housed with their main planes parallel to each other at equal mutual distances.
  • the perforated needles are generally used to feed the warp threads in the manufacture of ribbons, especially elastic ribbons.
  • tapes which contain more than 10 or 12 warp threads and possibly also elastic threads per centimeter of machine width.
  • the needles need to be poured into a carrier increasingly densely next to one another, in particular they have to be injected. Should z. B. 12 needles per cm machine width, a width of 0.83 mm is available for each needle.
  • the shaft already has approximately this width, so that there is no space left into which the cast material, namely light metal or plastic, can flow in order to anchor the needle shafts.
  • the aim of the present invention is that perforated needles can be used which have tips, ie working areas of e.g. B. only 0.3 mm thick but robust and relatively thick shafts ver can be applied. Nevertheless, a needle density of 12 and more per centimeter of machine width should be achievable.
  • this object is achieved in that that - two carriers, each with a group of needles (needle groups), are used to form a needle segment (segment), Grasp the heads of the needles in the first group of needles in the middle between two heads of the needles of the second group of needles, and alternate the heads of both groups of needles in the direction of the common row of heads, -
  • the two needle groups within the segment are fixed and arranged at an angle such that - An imaginary plane of one group of needles (group level), which extends along the needles and through the heads of this group of needles, intersects with the group level of the other group of needles in the area of the heads.
  • the heads of two groups of needles which are each cast in, in particular injected, alternate with one another.
  • the double needle density of previous needle segments can be achieved with relatively large perforated needles according to the prior art.
  • the holes of both groups of needles can be aligned with each other. But this is not necessary. There is also a shift of the heads of both groups towards each other in the direction of the head planes allowed.
  • the interlocking of the heads can be achieved by screwing conventional carriers of perforated needles from both sides onto a movement shaft of the machine. Then the two group planes, as defined in claim 1, form a relatively large but still acute angle with one another.
  • more than two, in particular three carriers, each with a needle group can form a common perforated needle segment, which creates the possibility of using perforated needles with particularly wide shafts and yet achieving a high thread density.
  • Conventional carriers of one group of perforated needles can be soldered to one another, which can be carried out with carriers made of metal, in particular light metal. If the supports are made of plastic, they can be welded or glued together.
  • the carriers of the needle groups can be poured into a common block, in particular injection molding, which is preferably applicable for large quantities and to achieve high precision.
  • FIG. 1 and 2 show a movement shaft 2 as it extends across the machine width in weft-knitting machines and can be rotated back and forth.
  • a flat surface 4 is milled on both sides of the movement shaft over its length.
  • the two surfaces 4 make an angle of e.g. 45 ° on.
  • three supports 8, 9, each with a group of six perforated needles 12, are screwed on both sides. In most cases, significantly more carriers are arranged next to each other. Each of them can have more than six, e.g. B. contain eighteen needles.
  • 5 and 5 ⁇ are two group planes that extend along the needles 12 through the heads 22 of both needle groups and intersect in the area of the heads.
  • One hexagon socket screw 10 is screwed through a hole in each of the supports 8, 9 and the intermediate plates 6, 7 into a threaded bore in the movement shaft 2.
  • the carriers 8, 9 each have a stop bar 14, which is located on the upper edge of the associated intermediate plate in FIG 6, 7 supports and serves to prevent rotation.
  • the two carriers 8, 9 with their perforated needles 12 together form a segment which works together with a group of knitting needles in the machine.
  • Each carrier 8, 9 is a cast body made of metal, in particular light metal or plastic, which holds the stems of the perforated needles 12 at the same mutual spacing with mutually parallel needle planes and aligned holes 20.
  • the heads of the perforated needles provided with the holes are considerably thinner than the shafts, so that there is sufficient space between every two heads into which a head of a second group of needles can be inserted and also sufficient space for those through the holes 20 guided warp threads.
  • FIG. 1 shows that the holes 20 of the heads of both needle groups are aligned. This is the ideal state, but it does not have to be achieved for an effective function. It is sufficient that the heads overlap one another, while the holes 20 of both needle groups can be slightly offset from one another.
  • FIG. 3 shows another embodiment in which two needle groups 24 and 25 are anchored in a carrier 27 and 28, but both carriers are seated on a common circuit board 30.
  • the two needle groups enclose a substantially smaller angle here than in FIG. 1.
  • the angle can e.g. B. be 11 °.
  • both carriers 24, 25 can be injection molded as a common block.
  • the carriers 24, 25 can be injection-molded individually and, if made of metal, can be soldered to one another. If the supports are made of plastic, they can be welded together and, if the necessary durability can be achieved, can also be glued together.
  • Segments according to Figure 3 are also attached to a motion shaft in the machine, but only on one side.
  • FIG. 4 shows a further embodiment with three carriers 27, 28, 29 for three needle groups 24, 25, 26.
  • the carriers are combined with one another in one of the ways described above. All three carriers sit on a common circuit board 30.
  • the heads of the needle groups 24, 25, 26, 24, 25, etc. follow one another.
