Definitions

  • This invention relates to knitting machine needles. More particularly, this invention is a novel knitting machine needle made from flat stock and wire stock.
  • the needle can be made more uniformly, accurately and stronger with more latitude to form the very complex butt configurations required to meet knitting machine pattern cam requirements and because of is solid rectangular cross-section, can operate better than other needles as they are reciprocated in slots formed in a knitting machine cylinder or knitting head.
  • it has also been found that it is more desirable to make the hook and blade section of the needle from wire stock.
  • the wire stock makes a better hook edge than flat stock. If flat stock were used for the hook and blade section, the hook often breaks much quicker than when wire stock is used. I
  • Our new knitting machine needle comprises a flat stock butt section and a wire stock for the hook and blade section which two sections are fused together along overlapping longitudinal portions of both sections.
  • the length of the fused portion should be at least fifteen times the thickness of the butt section.
  • FIG. 1 is a side view of the needle
  • FIG. 2 is an enlarged fragmentary view of the needle of FIG. 1;
  • FIG. 3 is a view taken along lines 3-3 of FIG. 2.
  • our new knitting machine needle includes a flat butt section 10 which is fused by welding or other fusion methods to a wire stock hook and bladesection 12.
  • the hook and blade'section includes a blade 14 with a hook 16 located at one extremity of the blade.
  • Latch 18 pivots about pivot 20 as the knitting needle is reciprocated in the knitting machine.
  • FIG. 2 shows clearly that the wire stock blade 14 is fused to a reduced height portion 22 of the. flat stock by fusion means such as welding 24.
  • the thickness of the weld is exaggerated in FIG. 2 for clarity.
  • the reduced height portion 22 flows into the remainder of the flat stock butt section 10 through a curved 10 portion 26.
  • the fusion 24 of the longitudinal portion of the blade section 12 is substantially equal to the length of the reduced height portion 22 of the flat stock butt section 10.
  • the length of the fused portion 24 should be at least times the thickness 30 (see 5 FIG. 3) of the flat stock butt section 10.
  • the knitting machine needle reciprocates in the same direction as its longitudinal axis. As the needle reciprocates, it is subjected to great tension and compression in the same direction as the reciprocating motion of the needle.
  • the curve section 26 in the flat stock butt section 10 eliminates any sharp corner at the junction of the wire stock blade 14 and the flat stock butt section 10. We have found that under some circumstances, the projection of sharp comers causes earlier fatigue failure than occurs when sharp comers are eliminated by the provision of curve 26.
  • a knitting needle comprising:
  • a wire stock hook and blade section a longitudinal portion of the blade section being fused to the reduced height portion of the butt section for a length at least equal to the length of said reduced height portion of the butt section.
  • the length of the fused portion is at least 15 times the thickness of the butt section.
