Definitions

  • the present invention relates to a sinker of circular knitting machines for pile fabrics, and more particularly to a sinker for circular knitting machines that provides a yarn positioning function during the weaving process.
  • the conventional sinker 31 comprises a nose section 32, a support surface 33 being a horizontal surface disposed on the nose section 32, and when the sinker 31 draws back in the final step of the weaving process, the weaving needle 34 pulls the bottom yarn and the binding yarn of a yarn loop 35 down. Since the support surface 33 does not have an inclined angle it is difficult to maintain the angle of a plating loop when the yarn loop falls. In other words, the angle of the plating loop is changed very easily when the yarn loop falls, and thus will cause low quality of fabrics.
  • the sinker cylinder containing the sinker is rotated at a high speed for weaving. Therefore, the sinker moves back and forth in the driving path of the cam during high-speed rotation.
  • a centrifugal force is produced to give the sinker a large outwards swinging force towards the exterior of the circular knitting machine, such that a protruded plate cannot move smoothly along the driving path.
  • the contact surface and contact angle of the protruded plate and the driving path form several stress focal points which are worn repeatedly by the centrifugal force.
  • the wear between the sinker and cam shortens their lifetime, and also increasing the cost of manufacture which in turn passes to the consumer..
  • the sinker cylinder contains thousands of sinkers, operators have to examine and replace them frequently, thus seriously affecting productivity.
  • the primary objective of the present invention is to provide a sinker with a perfect plating loop whilst knitting pile fabrics.
  • a perfect angle for the plating loop can be achieved by separating the old yarn ring from the aslant surface of the nose section when the weaving needle pulls the binding yarn and the bottom yarn lower than the abdominal section of the sinker.
  • Another objective of the present invention is to provide a sinker assembly for circular knitting machines.
  • the sinker comprises a first end surface disposed at its throat section and a second end surface disposed at its abdominal section. Since the contact surface between the cam and the sinker cylinder of the circular knitting machine is designed to be aslant, therefore the sinker is installed onto the circular knitting machine with an inclined angle. After the sinker is installed, the first end surface is horizontal and the second end surface is aslant.
  • the sinker of the circular knitting machine designed with the aslant feature is redesigned according to the principle of knitting movements for operating with circular knitting machines.
  • a sinker 10 comprises a nose section 11, a protruded nose 22, a throat section 12, and an abdominal section 13; wherein the nose section 11 has an aslant surface 111; the throat section 12 has a first end surface 121; the abdominal section 13 has a second end surface 131 on one side; and a limit groove 23 is disposed between the nose section 11 and the protruded nose 22.
  • the sinker 10 is installed on the driving path 24 (which is a track disposed between the take-up cam and take-down cam for driving a weaving needle for the vertical movement of the needle) of a cam 19 of the circular knitting machine by the protruded plate 21. Since the contact surface between the cam 19 and the sinker cylinder is inclined to an angle ⁇ , therefore when the sinker 10 is installed onto the contact surface, the sinker is also inclined to an angle ⁇ , and the first end surface 121 is in a horizontal position.
  • the driving path 24 which is a track disposed between the take-up cam and take-down cam for driving a weaving needle for the vertical movement of the needle
  • FIGS. 4A ⁇ 4G for the movements of the sinker 10 and the weaving needle 14 in the weaving process
  • FIG. 4A first.
  • a knitting needle 14 pulls a yarn loop 17 composed of a binding yarn 20 and a bottom yarn 16 down (see FIG. 4B ), while the sinker 10 is moving forward and the knitting needle 14 moves upwards for the take-up.
  • FIG. 4B The needle 14 hooks the wool yarn 18 and prepares for the downward pulling movement.
  • the yarn loop 17 falls to the root section of the weaving needle 14, and opens a latch needle 141.
  • the needle 14 pulls down the wool yarn 18 while the sinker 10 continues to move forward, such that the wool yarn 18 drives and hangs on a limit groove 23 between the nose section 11 and the protruded nose 22 of the sinker 10.
  • FIG. 4D The needle 14 is protruded upward, such that the wool yarn 18 opens the latch needle 141 and casts off to fall to the bottom of the latch needle 141 of the weaving needle 14.
  • the yarn loop 17 composed of binding yarn 20 and the bottom yarn 16 at the bottom of the latch needle 141 of the needle 14 (as shown in FIG. 4A ) further falls downward. Then, the needle 14 hooks the binding yarn 20 and prepares to pull down the binding yarn 20.
  • the wool yarn 18 and the binding yarn 20 still hook into the limit groove 23 between the nose section 11 and the protruded nose 22 of the sinker 10 after the wool yarn 18 and the binding yarn 20 are connected with each other into a string. Then, the needle 14 continues to move upward to halfway, so that the wool yarn 18 and the binding yarn 20 fall to open the latch needle 141, and the needle 14 hooks a bottom yarn 16, and then the yarn loop 17 falls down further.
  • the sinker 10 draws back to pull the needle 14 down, and also pulls the binding yarn 20 and the bottom yarn 16 connected to the wool yarn 18 down.
  • the yarn loop 17 composed of the binding yarn 20 and the bottom yarn 16 (as shown in FIG. 4A ) binds the binding yarn 20 and the bottom yarn 16 together to form the yarn loop 17.
  • the aslant surface 111 allows the yarn loop 17 to have a better angle for the plating loop.
