Definitions

  • FIG 1 is a schematic side view of an apparatus in accordance with the invention, with take-up of yam on cone
  • FIG 2 is a schematic side view of an apparatus in accordance with the invention, with take-up of yarn on tube
  • FIG 3 is a schematic view of a hollow spindle arranged for taking up the yam on tube
  • a production unit 1 of an apparatus for the production of fancy yams comprises the following parts supported by a first frame 10 - a reserve of yams 1 1 and/or rovings or slivers 12 on cones or cops 13 and/or bobbins 14, a feeding group and/or draft 15 of the yams and/or rovings,
  • first yarn forming group 16 comprising, in the illustrated example, a first hollow spindle 17 provided with a first flanged bobbin 25 of binding yarn 26, - a first delivery group, below the first hollow spindle 17 and comprising a first motorized cylinder 18, - a second ya forming group 19, positioned downstream to the first delivery group and comprising a second hollow spindle 20 provided with a second flanged bobbin
  • a second delivery group below the second hollow spindle 20 and comp ⁇ sing a second motorized cylinder 21 , a vertically movable ring 23 rail 22, as known in the art, along supports 24, located in the lower part of the 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 ya (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 yam produced to the take-up cones 31
  • Functioning of the above described apparatus is substantially the following a ya 100 is fed to the first hollow spindle 17 and subsequently to the second hollow spindle 20 Both hollow spindles are kept rotating by tangential belts, not shown in the figures
  • the resulting yam 101 comes out of spindle 20 and is then conveyed via duct 40 to the take-up group 32 and to the cone 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 yams that do not require the second binding yam 28, simply bypassing the second hollow spindle 20 Choosing the present solution it is possible to place the take-up groups 32 at an ideal height from the ground thus making all necessary operations extremely easy
  • the lower hollow spindle 20 holds, instead of a bobbin with binding yam, a tube 50 Additionally, the rail 22 has an alternate vertical movement, being each ring 23 substantially centered on the vertical axis of spindle 20 This permits to take up the yam 102 coming out of first hollow spindle 17 on a cop 29, quite similarly to the ring spindles system
  • 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
  • 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 ⁇ ng spindle
