Abstract
A package is wound using a drum having traverse grooves with different wind numbers. During the winding of the package, the drum wind number by which a supplied yarn is wound onto a package is changed to another drum wind number when the diameter of the package approaches a value at which ribbon winding occurs so that ribbon winding is prevented.
