Definitions

  • the needle selected sheet is driven by the needle-pushing cam in normal conditions so that the knitting needle at the front end of the needle selected sheet hooks and pulls a yarn to form a yarn loop, or at least one needle selected sheet is pushed by the needle selected device to escape from the needle-pushing cam, so that the knitting needle cannot be driven by the needle selected sheet to form the yarn loop.
  • the needle selected sheet has the return apparatus that is an elastic plate, an elastic rod or an elastic strut butting the upper needle dial to provide an automatic returning force for the needle butts of the needle selected sheet.
  • R.O.C. patent No. 435457 mentioned above has some drawbacks in practice.
  • the return apparatus is located on the needle foot of the jacquard needle, this limits the length of the return apparatus, and it also creates a longer movement distance when the jacquard needle is moved downwards.
  • the longer movement distance of the return apparatus results in a greater stress it has to withstand. Since the interior space of a circular knitting machine is limited, the thickness of the return apparatus is difficult to increase, thus the lifespan of the return apparatus also is shorter.
  • the jacquard needle 2 includes a fulcrum 21, a neck 22, a force received section 24 connected to the neck 22, a needle foot 26 extended from the force received section 24 and the return structure 25.
  • the fulcrum 21 is connected with the knitting needle 4.
  • the neck 22 is extended from the fulcrum 21.
  • the neck 22 is extended upwards to form a shoulder 23 perpendicular to the upper needle dial 5.
  • the neck 22 is connected to the force received section 24 through the shoulder 23.
  • the force received section 24 is located at a higher horizontal elevation than the neck 22 in the circular knitting machine through the shoulder 23.
  • the force received section 24 has a plurality of needle butts 241 depressed by the needle selected sheets 11.
  • the force received section 24 also is extended to form the needle foot 26 which is located in a slide track formed on the cam 3 in the normal conditions.
  • the return structure 25 is extended from the neck 22 and has a distal end formed a bend end 251 beneath the needle foot 26.
  • the return structure 25 is formed at an arch from the neck 22 to the bend end 251.
  • the bend end 251 butts an inner wall of the upper needle dial 5.
  • the return structure 25 and the force received section 24 are interposed by a retraction gap 27 to provide a movement space for the force received section 24 while depressed by the needle selected sheet 11.
  • the shoulder 23 has an arched notch 231 at one end of the retraction gap 27.
  • the return structure 25 previously discussed can be an elastic plate, an elastic rod or an elastic strut. While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
  • the present invention provides a significant improvement over the conventional techniques and complies with the patent application requirements, and is submitted for review and granting of the commensurate patent rights.
