Definitions

  • the invention relates to a needle bed for circular knitting and circular knitting machines according to the features of the preamble in claim 1.
  • a needle bed of this type is known from US Pat. No. 3,290,900, where two webs of greater height and a web of lower height lying between these webs form a needle guide channel.
  • Several needle guide channels are combined into a segment which has an L-shaped segment carrier strip on the bottom.
  • the recesses in the segment carrier strip in connection with the spaces between the needle guide channels are poured out to bond the segment with metal.
  • the segment carrier strip has threaded holes on the bottom for engaging clamping screws in cylinder bores.
  • the object of the invention is to significantly simplify the segment structure of the individual segments to be clamped to the cylinder in a needle bed of the type mentioned.
  • the machine cylinder 11 is of relatively simple design and can be machined extremely precisely and precisely on a lathe. Insofar as grinding work is required, it can also be carried out in a simple manner, which ensures rational and cost-effective production of the machine cylinder.
  • the needle bed itself is formed by the segments 12 fastened to the circumference of the cylinder, which are clamped to the latter and bear tightly against one another.
  • the individual needle bed segments 12 consist of a multiplicity of flat webs 13 and 14, of which the webs 13 have a greater height in the radial direction than the lower webs 14, which alternate with one another in a regular sequence, so that a web is formed in each case between webs 13 which are considered in which the needles are stored and can be moved up and down; they slide on the outer surface of the flat lower webs 14.
  • the webs 13 and 14 are made of a suitable material that is easy to harden so that the guideways for the needles can have any desired surface hardness.
  • each needle bed segment 12 In order to firmly connect the individual, closely abutting surfaces of the steps 13 and 14 of each needle bed segment 12 to form a compact element, there are recesses 15 forming grooves on the underside facing the cylinder 11, into which a metal in the liquid state or possibly also Plastic is poured or injected, which material after solidification forms bars or strips 16 extending across the entire width of the segments and causes the webs 13 and 14 to hold together.
  • parallel keys or strips 20 are arranged on the underside of the segments, which engage in grooves 21 arranged on the cylinder 11. Furthermore, stop surfaces 22 and 23 can be provided on the cylinders or on the segments 12, which abut one another.
  • the webs 13 are advantageously at their upper end 24 on the inside 25 facing the axis of the cylinder 11 in the region of the
  • the knock-off position of the needles is provided with a recess 26, which is intended for receiving a wire 27 of a wire ring made of hardened material, which serves to place the needles in the knock-off area and as a knock-off edge.
  • This measure makes it possible to obtain a particularly uniform and better mesh structure than before.
