  • the lead ratio in the first embodiment and the second embodiment has been described as the value of the ratio of the traverse time, but the lead ratio may be set as the value of the ratio of the traverse speed.

  • the package 53 can be wound even if the lead ratio is set as the value of the ratio of the traverse time or as the value of the ratio of the traverse speed.
  • the configuration for controlling the operation of the yarn winding device 11 is not limited to the embodiments, and for example, the winding bobbin drive control section 31 and the traverse control section 34 may be arranged in the unit control section 41, or the lead ratio setting section 43 arranged in the machine control section 42 may be arranged in the unit control section 41.
  • the winding bobbin B is directly driven by the winding bobbin drive motor 18, but a drive roller may be made in contact with the surface of the winding bobbin B to drive the winding bobbin B.
  • the shape of the contact roller 14 is a conical shape in which the diameters of both ends are different, but the shape may also be a cylindrical shape in which the diameters of both ends are the same.
  • the traverse device 12 is configured such that a longitudinal direction of the arm member 16 is parallel to an installing direction (vertical direction) of the yarn winding device 11, but the traverse device 12 may be configured such that the longitudinal direction of the arm member 16 is perpendicular to an installing surface of the yarn winding device 11.
  • the traverse device 12 is configured such that the arm member 16 reciprocates by the traverse guide drive motor 19, but an endless timing belt may be arranged in proximity to the contact roller 14, the traverse guide 17 may be attached to the timing belt and the timing belt may be reciprocated by a pulse motor, or the like.
