  • the first embodiment may adopt the positional relationship between the blower box 5 and the open-end spinning unit 6 similar to that in the second embodiment.
  • the automatic winder 1x of the present embodiment includes the winder unit 2x adapted to unwind the spun yarn 10 from the yarn supplying bobbin 19 and wind the spun yarn 10 into the first package 16x.
  • the excess fibers 13 generated in the winder unit 2x can be efficiently reused in the open-end spinning unit 6.
  • only one open-end spinning unit 6 is arranged.
  • two or more open-end spinning units 6 may be provided.
  • the open-end spinning units 6 may be arranged on both sides of the blower box 5.
  • the excess fiber bundle 15 converged by the fiber bundle forming device 7 is directly supplied to the open-end spinning unit 6.
  • the present invention is not limited thereto, and the excess fiber bundle 15 converged by the fiber bundle forming device 7 may be once collected in an appropriate container (e.g., can) by an operator, and the collected excess fiber bundle 15 may be supplied to the open-end spinning unit 6.
  • the open-end spinning unit 6 may carry out the spinning with only the excess fiber bundle 15 collected in the can.
  • the spinning may be carried out by supplying a sliver from a drawing frame to the open-end spinning unit 6, or the spinning may be carried out by supplying the excess fiber bundle 15 to the open-end spinning unit 6 at a time point at which the amount of excess fiber bundle 15 reaches a certain extent.
  • the configuration of the fiber bundle forming device 7 is not limited to that described in the above-described embodiment.
  • the number of drawing rollers 73 is not limited to one pair, and may be two or more pairs.
  • the yarn supplying bobbin 19 may be supplied to each of the winder units 2x by the magazine type supplying device or may be supplied by the bobbin supplying mechanism using a conveying tray.
  • the configuration of traversing the spun yarn 10 when forming the first package 16 is not limited to using the traverse guide 29 of FIG. 1 .
  • the arm type traverse device or the belt type traverse device may be individually provided in each of the spinning units 2.
  • a traverse groove may be formed on a surface of the winding drum which causes the first package 16 to rotate accompanying rotation of the winding drum, and the spun yarn 10 may be traversed with such a traverse groove.
  • the fiber bundle forming device 7 used in the spinning machine 1 and/or the automatic winder 1x includes the guiding member 70 having the first opened portion 70a, through which the excess fibers 13 are guided in, and the second opened portion 70b smaller than the first opened portion 70a; the converging section 71 adapted to converge the excess fibers 13 guided out from the second opened portion 70b; the receiving roller 72 adapted to receive the excess fibers 13 converged by the converging section 71; the drawing roller 73 adapted to draw the excess fibers 13 from the receiving roller 72 to form the excess fiber bundle 15, and to convey the excess fiber bundle 15 to downstream; and a supporting section (not illustrated).
  • the supporting section is adapted to support the guiding member 70, the converging section 71, the receiving roller 72, and the drawing roller 73 as a module.
  • the supporting section is a frame member, and the guiding member 70, the converging section 71, the receiving roller 72, and the drawing roller 73 are attached to the frame member.
  • the fiber bundle forming device 7 can be easily attached/detached as a module with respect to the spinning machine 1 and/or the automatic winder 1x.
  • one collecting section is provided with respect to the spinning machine 1 and the automatic winder 1x.
  • a plurality of collecting sections may be arranged in accordance with the number of spinning units 2 in the spinning machine 1 and/or the number of winder units 2x in the automatic winder 1x.
  • one collecting section may be provided for every predetermined number of spinning units 2, and at least one open-end spinning unit 6 may be provided with respect to one collecting section.
