Abstract
A yarn package which is provided with a saw-shaped traverse stroke profile, similar in some respects to that of a pine cone, and to a method for winding the same. This shape, by providing a periodic variation in the effective winding height, minimizes irregularities in the yarn due to compression and relaxation stresses.
