Definitions

  • the invention relates to a perforated needle segment for use on crochet or Raschel machines with the individual features of the preamble of claim l.
  • Such perforated needle segments essentially consist of a carrier body connected to a movement-driven part of the machine and a plurality of perforated needle lamellae which protrude parallel and equidistantly from a side face, namely from an end face of the carrier body.
  • the perforated needles are at their free ends with a hole for performing a u. U. elastic thread section provided, with its fastening end, the needles are held in the carrier body.
  • the segments are attached to a cross member, which has an elliptical rotational movement with a relatively high rotational frequency executes, not inconsiderable mechanical forces act on the connection between perforated needles and carrier body.
  • the invention / innovation is based on the object of developing a perforated needle segment of the type described above in such a way that it reduces weight and at the same time a permanently firm bond between the carrier body and the perforated needle lamella is ensured.
  • the segments should also be easy to manufacture and inexpensive by saving on metallic raw materials.
  • the core of the invention / innovation it is considered to arrange at least one rod-shaped cross connector in the area of the fastening ends of the perforated needle lamellae, which is firmly connected to the fixed ends of the individual lamellae and runs within the carrier body over the entire width of the perforated needle arrangement essentially at right angles to the longitudinal direction of the needle.
  • This cross connector ensures a firm hold of the needles with one another and at the same time ensures that the entire perforated needle assembly cannot become detached from the support body through the cross strut in the support body material. If the rod-like cross connector is still raised beyond the side edge of the perforated needle fixed ends, a positive connection is established with the carrier body material and the hold is increased even further.
  • the carrier body consists of plastic material, in particular ABS plastic, since the prepared and provided with the cross connector piercing needle set can then be easily injected or poured into the plastic body.
  • a plurality of cross-connectors on both sides in the area of the fastening end of the perforated needle lamellae ensures that the perforated needle package prepared for injection does not twist or bend, with the result that the individual perforated needles lose their equidistance to one another.
  • the cross connector (s) advantageously consist of welding wire and are attached to the back of the needle lamellae by means of an electric welding process.
  • the welding wire also has an advantageous effect in that it has a certain flexibility, which allows the prepared perforated needle assembly to be re-aligned after insertion into corresponding recesses in the injection mold for the production of the carrier body and thus to ensure that the perforated needle alignment is really exact.
  • a tripartite arrangement of the cross connector has proven to be particularly advantageous statically.
  • a really intimate connection between cross connector and perforated needle lamellae can be achieved by providing the back or side edges of the perforated needle lamellae with U-shaped recesses into which the cross connector designed as a welding wire is inserted.
  • the radius of the U-shaped recesses corresponds approximately to the radius of the welding wire, so that there is a relatively long welded connection.
  • the cooling plastic shrinks by about 0.8% - 1% after the injection process, the comb-like needles tend to bend open like a fan, ie to take a slightly greater distance in the area of their needle tips than in the area of the needle ends.
  • Such expansion by contraction of the plastic is avoided by reducing the tension in the area of the plastic back through recesses, which are advantageously a plurality of recesses that extend parallel to one another in the longitudinal direction of the needle between the fastening hole and the perforated needles.
  • the recesses have the shape of elongated holes.
  • a further stiffening of the carrier body is achieved in that a plurality of stiffening ribs are provided, which in particular enclose the edge of the carrier body and at least partially run in the center of the carrier body in the longitudinal direction of the needle.
  • a reinforcement of the support body is also provided, which merges into the stiffening ribs. This prevents the carrier body from breaking out in the area of the fastening hole under high loads.
  • the perforated needle segment 1 shown in Fig. 1 for a crochet and / or Raschel machine consists essentially of a carrier body 2 and a plurality of needles 4 protruding from the end face 3 of the carrier body 2, which have a flat-rectangular cross section, equidistant and parallel to each other are arranged and are provided at their free end 5 with a hole 6 for the passage of a thread section and are held with their fastening end 7 in the carrier body.
  • rod-like cross connectors 8, 9, 10 are arranged, which are firmly connected to the fixed ends 7 and run within the carrier body 2 over the entire width 11 of the needle arrangement essentially at right angles to the longitudinal direction 12 of the needle.
  • the cross connectors 8-10 are raised beyond the side edge l3 of the fastening ends 7 of the needles 4, as can be clearly seen from FIG. 3.
  • the cross connectors are made of welding wire and have a round cross-section, the coupling between the individual lochna made via the cross connector 8-10 deln 4 is elastic.
  • the perforated needle lamellae In order to achieve the most intimate welded connection, the perforated needle lamellae have l3 U-shaped recesses in their side edges, the diameter of which corresponds approximately to the diameter of the cross connector 8 - l0 made of welding wire.
  • the carrier body has a rectangular cross section and a fastening hole 16 at its end facing away from the needles 4.
  • FIG. 4 shows the second side of the perforated needle segment, which is opposite the first side shown in FIG. 1.
  • the carrier body 2 is provided with a plurality of recesses 17, which are partly between the fastening hole and the needles 4.
  • the recesses l7 are elongated holes, the longitudinal axis of which extend in the direction of the needles 4. 4 that the support body 2 has a plurality of stiffening ribs l8, l9, the stiffening ribs l8 being arranged on the edge of the support body 2 and extending into the region of the support body which receives the fastening hole l6.
  • the stiffening rib l9 extends towards the center of the fastening hole l6 parallel to the direction of the needles.
  • the carrier body has an additional reinforcement 20 which merges into the stiffening rib l9 in the region 2l.
  • the reinforcement 20 is designed so that the head a fastening screw finds a support surface running parallel to the flat side of the carrier body shown in FIG.
