Definitions

  • the invention relates to a circular knitting machine with a set of latch needles, which are arranged around a cylinder, and with a drive.
  • the solution to this problem according to the invention is that the cylinder can be moved vertically up and down by the drive, while the set of needles remains at rest.
  • the needles which in turn are of conventional construction and are arranged in a circle around a cylindrical tube or the cylinder, are stationary and the knitting is effected during an up and / or down movement of the tubular construction.
  • One of the advantages achieved with circular knitting machines is an increase in the speed at which the goods are produced.
  • there is a considerable saving on needles because the latter are less subject to wear, tearing and breaking.
  • a base plate 15 can be seen there, on which two leaf springs 8 are arranged one above the other at a distance from one another and are held at one end by blocks 8 '.
  • the opposite end of the leaf springs 8 is attached to a cylindrical tube or cylinder 5 in a manner to be described.
  • This cylinder 5 is mounted on an annular element 6 which, for practical reasons, is composed of two semicircular parts.
  • the element 6 extends with a part of its circumference into the gap between the two leaf springs 8 and is firmly attached to it with screw bolts 6 'and 9.
  • the two halves of the element 6 are interconnected by screws 7, of which only one can be seen in the figure.
  • the cylinder 5 carries a needle bed 1, the needles 2 being arranged in the spaces between the individual members thereof, only a few of which can be seen in the drawing for reasons of clarity.
  • the needle bed 1 is in two Ring elements 3, 4 held, which are screwed onto a cover plate covering the springs 8.
  • a thread carrier with a circular flange plate 11 is arranged above the needles 2, which extend upwards from the needle bed 1.
  • An arm cross 10 with a circular cylindrical bore is fastened to the flange thereof, through which a shaft 11 'passes, which can be rotated in a sleeve 10' rising from the arm cross 10.
  • the shaft 11 ' carries a radially extending lever 13 near its head, while a similar lever 12 is attached to the sleeve 10'.
  • the movement of the thread carrier is derived from these levers 12, 13, which are actuated by cam disks.
  • the relevant cam not shown, moves the lever 12 oscillating through an angle, so that the thread carrier is rotated from one needle to the next.
  • the function of the machine is as follows:
  • the thread is fed to the machine from conventional conical bobbins, which are held in a bobbin case as usual, and reaches the thread carriers 10, 11 under tension.
  • the thread carriers have bores, which are represented by dots in the drawings; According to the respective individual thread length, several holes are made for each needle 1, ie as many as there are needles in the individual case.
  • the thread carriers 10, 11 move horizontally and insert the thread into the needle heads when the loops formed have passed the tongues, as can be derived from FIGS. 3 (A, B, C, D).
  • the inner position is in the position shown in FIG. 3A Tube or cylinder 5 in an intermediate position. In position B the cylinder 5 moves downwards to clear the tongue of the needle 1.
  • Position C shows that the cylinder 5 moves with the fabric upwards, so that the stitch closes the needle tongue and falls into the knitted fabric.
  • the cylinder 5 moves up to the knock-off position in order to form the new stitch through the previous one. Whenever the cylinder 5 lifts, the stitch formed is withdrawn from the needle 1 and a new stitch is formed, which is continued as long as the thread is fed to the machine.
  • the up and down movement of the cylinder 5 is effected by a cam disk, the cylinder 5 being held by a pair of flat springs 8, as has already been mentioned.
