Definitions

  • the invention relates to a mechanical take down device in a circular knitting machine, particularly a double cylin­der knitting machine.
  • the task of the invention is to eliminate the above-­mentioned disadvantages, what is principally achieved, so that the device comprises two coaxially arranged circular parts with the fabric passing between them, the surface of one of said parts coming in contact with the fabric is provided with a screw-like surface and one of them is ar­ranged non-rotatably.
  • the advantage of the invention is that the device is very simple and not demanding as to the operation and servi­cing. Due to the fact that it acts around the whole peri­phery of the fabric by a continuous pull, it entirely eli­minates creation of longitudinal bars and practically en­ables knitting of infinitely long products and replaces thus even a roller take down. Moreover, it smoothes up the fabric surface and the fabric quality is better. The de­vice does not need to be adjusted and there is practically no wear, what guarantees its long service life. Faults due to the function are also entirely eliminated. The device can operate like upper or lower take down.
  • a known double cylinder circular knitting machine for the production of sock goods is provided with a lower and up­per needle cylinder, 1, 2, where there are located double-­head needles 3 and further, known, not shown jacks to con­trol needles 3.
  • the machine is further provided with knock over sinkers 4 in the lower needle cylinder 1 and with stationary presser sinkers 5 in the upper needle cylinder 2.
  • Knocking over sinkers 3 are controlled by stationary cam rings 6, 7 fixedly arranged on a non-rotary tube 8.
  • the machine is equipped with a mechanical take down device comprising the following parts.
  • a mechanical take down device comprising the following parts.
  • the lower needle cylin­der 1 there is a part 10 of a funnel-like shape with a central opening for fabric passage fixedly arranged on an internal rotating take down tube 9.
  • an axially shiftable part 11 In the upper needle cylinder 2 there is arranged an axially shiftable part 11, the working part of which is formed like an external, co­nical, screw-like surface 110. Both parts 10 and 11 fit into each other, while the slope of internal conical sur­face 100 (Fig. 2) of part 10 corresponds with the conical screw-like surface 110.
  • Both parts 10 and 11 are arranged coaxially, while part 11 is located rotatably and shiftab­ly in rings 12, 13 which are fixedly arranged in an inter­nal tube 14 of the upper needle cylinder 2, while the tube 14 rotates with the neelde cylinder 2.
  • a lever 15 located swingably in a stand 16 on upper flange 17 of the machine. The other arm of the lever 15 is controlled by the machine control drum through a not shown kinematic transmission.
  • part 11 is lifted so that the device is out of operation.
  • Fabric P grows longer, while it contracts to the center due to laying of elastic thread.
  • part 11 (Fig. 3) is lowered by a command from the control drum.
  • Fabric P is pressed by a conical screw-­like surface 111 onto the internal conical surface 110.
  • Pressure of part 11 causes entrainment of fabric P by rotating part 10. Due to the rotation, the fabric P is in fact screwed into the surface of conical screw-like sur­face 110 and it is thus in fact tensioned and taken down from the needles 3.
  • part 11 is lifted by a command from the control drum and the fabric is cast off the needles 3.
  • the operation of parts 10 and 11 can proceed in opposite sequence.
  • the upper part 11′ (Fig. 8) is provided with a conical surface 110′ and the lower part 10′ with a screw-like conical surface 100′.
  • the fabric is tensioned and taken down by the part 10′.
  • Another modification representing no change in the prin­ciple of the solution consists in that the rotary loca­tion is changed.
  • the lower part 10 or 10′ is arranged non-­rotatably and the upper part 11, 11′ is arranged as dri­ven.
  • the surfaces by which the parts fit into each other do not need to be conical, but they may be for exam­ple of a cylindrical shape, as evident on parts 11a, 10a in Figs. 4 and 5, or they may be formed in adjacent plane faces of parts 11b, 10b (Figs. 6 and 7).
  • the take down device can be arranged for upper take down so that the part with the opening, for example the part 10, is arranged in the upper needle cylinder, and the full part, for example the part 11, in the lower cy­linder.
  • the full part in the lower needle cylinder is not axially shiftable and the part with the opening for fabric passage is axially shif­table.
  • the device according to the invention can be used even in single cylinder knitting machines and also in large diame­ter knitting machines.
