Abstract

A servicing apparatus for automatic repair of yarn breaks in open-end spinning machines is provided with a device for replacing finished yarn packages with empty tubes, and a multi-functional yarn manipulating element having a work head equipped with a yarn brake and a contoured yarn guide element, the manipulating element being selectively movable between a position (c) at a top end of the tube for forming a top winding at the completion of winding a full yarn package, a position (a) at a base end of the tube for forming a yarn reserve winding upon beginning the winding of an empty tube, and a position (b) moving axially along the tube to prevent the creation of parallel windings during the repair of a yarn break.
