Abstract
A yarn winding method and resulting yarn package are disclosed, and wherein the yarn is wound onto a supporting tubular core by a traversing yarn guide and in accordance with either a random wind or a stepped precision wind. In each case, the winding is begun with the traversing speed having a predetermined initial mean value, and the mean value is then increased from the initial mean value to a predetermined maximum mean value, and such that the maximum value is reached when a predetermined base layer having a thickness (SB) of no more than about 10% of the total yarn layer thickness (S) of the finished yarn package is produced. The predetermined maximum value may be maintained during the remainder of the winding operation, and in addition, the circumferential speed of the package may be reduced during the initial increasing of the mean value of the traversing speed, and such that the winding speed and tension of the yarn remain substantially constant.
