Definitions

  • the present invention relates to the field of textiles and more precisely it relates to a method for preparing a rove with untwisted fiber for further textile working, in particular knitting or weaving.
  • the invention relates to an apparatus that carries out this method.
  • yarns are known used in textile applications. Such yarns are featured by a certain resistance to stretching actions, since the fibres are tied to one another by twisting as a direct step of the spinning process.
  • Yarns are often supplied wound on cones, that are prepared on spooling machines pr directly on spinning, for example of the type "Ring Frame” or “Self Acting".
  • the yarn is supplied from beam on which are wound parallel annular coils or hanks of carded rove, obtained from carding.
  • the cones have the function to allow an easy supply of yarn to the thread guides of textile machines, in particular knitting machines.
  • a rove is used directly as comes out from carding. More precisely, the hanks are extracted one at a time from the beams and from each of them the rove is gently pulled.
  • this step is subject to break of the rove, since the fibers of the latter are not twisted, and that stops knitting or weaving.
  • the hanks coming from the beam do not have a conical shape, for an ease supply of the rove pulling it from the above, and are only suitable for being unwound with a contemporaneous rotation about their own axis.
  • unwinding has to be very slow, since the rove does not allow stretching, unless in a controlled way.
  • the machines for handling an already spinned yarn are not are suitable to handle directly a rove since they all work with a certain stretching action on the yarn, which the rove cannot support.
  • Such a rove can be made by carding a desiredtextile fiber, for example natural fibers such as wool, cotton, as well as sinthetic fiber such as viscose, etc.
  • a desiredtextile fiber for example natural fibers such as wool, cotton, as well as sinthetic fiber such as viscose, etc.
  • a method for preparing a rove with untwisted fiber for a further textile working provides the step of winding the rove with untwisted fiber directly on a cone.
  • the cone has conical shape in order to allow drawing the rove with untwisted fiber from the above.
  • the step of winding the rove with untwisted fiber on cones according to the invention comprises, preferably, the steps of:
  • the steps are provided of:
  • an apparatus for preparing a rove with untwisted fiber for further textile working comprises:
  • the cones with the relative dragging shaft can be arranged directly at the exit of carding, in a same number as the roves that are coming therefrom, the means for controlling the speed causing the rotation of said cones at a tangential speed substantially the same as the speed of said roves that are coming from carding .
  • means for unwinding the roves, comprising guides, deflectors and counter rotating dragging rollers.
  • the means for unwinding can comprise also means for giving to the rove a light stretch or a light twist or false twist. This does not change the final open or untwisted structure of the rove on the respective cones.
  • an apparatus for preparing a rove 1 with untwisted fiber for further textile working for example knitting or weaving, yarn treatments, sewing, etc., provides the step of winding the rove on a plurality of cones 2.
  • the step of winding the rove on cones 2 provides the step of arranging on a spooling machine 5 according to the invention a beam 3 having a plurality of hanks 4 of rove.
  • the beam 3 rests on a tangentially dragging roller 6 which has a friction surface , for example splined, and rotates at a predetermined dragging speed by means of a drive 7. Furthermore the beam 3 is held by support arms 8, which can be lowered for its loading/sloading.
  • the cones 2, in a number at least the same as hanks 4, are mounted on idle supports 10. On each cone 2 an end of a rove 1 is arranged.
  • the idle supports can be opened quickly by means of handles 14.
  • each rove 1 proceeds from the relative hank 4 of beam 3 to the respective cone 2 without being stretched.
  • Rocking arms 13 are provided operated by not shown means, known in the spooling machines, for carrying out a cross winding of the rove on cones 2 and for guiding it during winding.
  • the roves 1 can be wound on cones 2 directly at the exit of a carding plant.
  • the supports 10 and the shafts (or the shaft) 11 are arranged directly at the exit of carding.
  • the unwinding hanks 4, instead of the tangentially dragging rollers 6, can be operated directly by the beam 3 axis with a suitable speed control responsive to the feeding speed.
