Definitions

  • the present invention relates to an improved apparatus for the production of fancy yarns.
  • a production unit 1 of an apparatus for the production of fancy yarns comprises the following parts supported by a first frame 10:
  • a second frame 30 is contemplated in front of the production unit 1.
  • said second frame 30 supports, for each production unit 1, a take-up group 32 - known in the art - comprising a cone 31, being its axis horizontally positioned and substantially parallel to the front side of the production unit 1.
  • Each cone 31 is mounted loose on lateral supports 33 and rotates by means of a motorized cylinder 34 peripherally grooved to guide the yarn (not shown in the figures).
  • the take-up groups 32 are positioned, on frame 30, on two overlapped rows.
  • transporting means comprising a motorized chain 36.
  • a duct 40 located between the frames 10 and 30 and lying inside a footboard 41, is provided for the pneumatic conveyance of the yarn produced to the take-up cones 31.
  • the ring 23 rail 22 does not operate and is kept at such a height as not to interfere with the lower hollow spindle 20.
  • the apparatus may also be used to produce yarns that do not require the second binding yarn 28, simply bypassing the second hollow spindle 20.
  • the lower hollow spindle 20 holds, instead of a bobbin with binding yarn, a tube 50.
  • the rail 22 has an alternate vertical movement, being each ring 23 substantially centered on the vertical axis of spindle 20.
  • FIG. 3 illustrates in details the adaptation means that permit to install a tube 50 (traced with a broken line) on the lower hollow spindle 20 and to obtain the formation of the cop 29 (also traced with a broken line).
  • Said means comprise a lower bushing 52 and an upper bushing 53, both fixed on the shaft 54 of the hollow spindle by means of threaded bolts, not shown in the figures.
  • buttons 55,56 are arranged, displaced by 120° and subject to the action of a spring 57,58, for the engagement of the tube 50. In this way the centering of the tube 50 and the correct formation of the cop 29 are assured.
  • the take-up groups 32 on cones 31, previously described do not operate and, simply removing the second bobbin 27, installing a tube 50 on the lower hollow spindle 20 and constraining the tube on the rotating base of the spindle, the machine with two hollow spindles is converted into a machine with one hollow spindle and one ring spindle.
