To solve a problem that a conventional traverse method performing a traverse jump can not cope with the formation of winding packages with varying traverse widths while coping only with the packages having shapes of such as a cone or a cheese that has a specific package width, since the traverse width is fixed during winding yarn regardless of the diameter of the package.

Twill angle control that combines winding at the fixed number of winds and the traverse jump is performed. At the same time, yarn Y is wound onto the package while being traversed. The twill angle θ of the yarn Y is controlled in relation to the traverse width S according to winding progress.
