PURPOSE:To provide a core-shape package nearly constant in release tension during high speed release in either large or small case of the package diameter and almost free from the generation of latching and sloughing. CONSTITUTION:In a package 4 wound with spun yarn into a core shape, the tapered angle of one yarn around the folded point 1 of yarn 5 at the large diameter side end face of the package 4 is made smaller than that of the other yarn, and the yarn is wound more tightly in the vicinity (F) of the large diameter part than in the vicinity (E) of the small diameter part. |
