PROBLEM TO BE SOLVED: To prevent generation of step wind or twill omission at a package end part. SOLUTION: When winding a yarn around a bobbin with step precision or the like, the yarn is wound at a predetermined twill pattern while keeping a constant locus of the yarn path at a turn part, and a twill angle pattern in a center part is controlled so as to be agreed with a desired wind number.
