Abstract
A method of winding a continuously advancing yarn to form a package, and so as to define an initial winding time T and a normal winding time. During the normal winding time a contact roll is positioned to lie against the surface of the package being formed, and the winding spindle speed is controlled by the contact roll. During the initial winding time T, however, the rotational speed of the winding spindle is controlled by a speed change function, which associates in the course of the winding cycle a certain winding spindle speed to each package diameter, while maintaining a constant yarn speed during the winding.
