Abstract

A method for avoiding irregular or ribbon windings while winding cross-wound bobbins with scrambled windings, including a movable bobbin holder for supporting a bobbin and a frictionally-driven drive cylinder for contacting the bobbin includes continuously lifting the bobbin holder to different heights and lowering the bobbin holder causing the duration of the contact between the bobbin and the drive cylinder to continuously change, and a device for carrying out the method.
