Method and device for avoiding the formation of irregular turns during the winding of a cross-wound coil

摘要

Method of avoiding the formation of irregular thread turns during the winding of a cross-wound coil driven by a drive drum formed with reversing thread grooves cooperating with a thread guide, a rotating element connectible to the cross-wound coil being braked with a varying braking force, which comprises the steps of continuously varying the peripheral velocity of the drive drum, and simultaneously braking, at least one of the cross-wound coil and the rotating element connected thereto, with a variable braking force in such manner that the peripheral velocity of the cross-wound coil remains constant within given tolerance limits.
