  • the invention relates to a latch needle for knitting machines, and more particularly to a latch needle with A a double foot.
  • the needle is stamped out of flat band steel.
  • a double foot gives a needle, the foot of which requires a relatively large width of at least 5mm, better shock-damping characteristics than a single needle foot construction of corresponding width.
  • the present invention provides means to efficiently dampen or possibly to completely suppress the propagation of shocks during needle control movements, shocks movement that can extend as far as the hook portion of the latch needle.
  • shocks movement that can extend as far as the hook portion of the latch needle.
  • a latch needle for knitting machines that is stamped out of flat band steel and com prises a double foot.
  • a zone of separation between the two foot portions extends to below the level of the adjacent edge of the needle shank.
  • the needle shank is provided with recesses in the edge areas opposite to the foot portions. Furthermore, the opposing edges of the two foot portions extend, according to a yet another feature of the present invention, at an incline inwardly towards each other. This combines good strength properties with different widths of the foot portions, and involves changes of cross-section in the direction of the propagation of shocks.
  • the two foot portions be terminated at their respective outer edges by recesses extending below the outer level of the needle shank edge, to form a cut-outs. This provides optimum reduction in the rigidity of the broad stamped-out flat band steel foot such as many known knitting machine needles require.
  • the latch needles of the present invention may be made in a single stamping process, and thus involve little extra cost as compared with known needle forms.
  • FIG. 1 is a plan view of the flat side of a latch needle according to the invention.
  • FIG. 2 is a side view of one edge thereof.
  • a latch needle is shown stamped out of a flat steel band, having a needle shank 1 which merges into a cross-sectionally reduced hookcarrying portion 3 terminating in a hook means 2.
  • the portion 3 extends from the hook means 2 substantially half the distance to the double foot.
  • Shank l carries a latch 4 co-operating hook 2 at one end, and a double foot having parts 5 to 9, including two foot portions 5 on the opposite end of the shank 1.
  • the longitudinal axes of the portions 5 are substantially perpendicular to the lengthwise or main axis of the needle.
  • the longitudinal edges of the shank are substantially parallel.
  • a zone of separation or gap 6 between the two foot portions extends to below or within the outer level of the adjacent edge of the needle shank 1.
  • the needle shank is provided with a recess 7.
  • Adjacent or opposing edges 8 of the two foot portions 5 extend at an angle, inwardly narrowing towards each other.
  • the outer tennination edges of the foot portions 5 are provided with respective recesses 9 extending below the lengthwise edge of the needle shank 1, as shown.
  • a latch needle for knitting machines stamped from flat steel strip comprising;
  • said shank further including a pair of recesses in an edge opposite to that which carries said foot portions, said recesses being disposed substantially opposite to and in line with the longitudinal axes of said foot portions, the axes being substantially perpendicular to the longitudinal axes of said shank, said foot portions having respective outer termination edges, and wherein further recesses are provided in said needle shank at said termination edges, said further recesses extending below said one edge ofthe shank.
