ABSTRACT:
A method and apparatus for winding a continuously advancing yarn to form a package, wherein the package is wound on a driven winding spindle that is mounted in cantilever fashion on a movable spindle support. A contact roll lies with a contact force against the circumference of the package. The contact roll is likewise mounted on a movable support, and during the winding cycle, the center distance between the package and the contact roll is increased by a deflection of the spindle support. In this process the drive of the spindle support is controlled by means of a control device which is connected to a sensor that detects the lift of the contact roll. In accordance with the invention, the drive of the spindle support is driven at a deflection speed when the contact roll is outside of its desired range, and at a lower reversing speed when the contact roll is in its desired range.
