Abstract

The assembly for winding yarn on a thread package comprises electrically operated friction drive means and electrically operated axial drive means. The mandrel tube which carries the bobbin tube and the thread package is frictionally driven. The mandrel itself is axially driven by the electrically operated axial drive means. The friction drive and the axial drive are effective to operate in tandem. The friction drive comprises a synchronous motor. The axial drive includes a three-phase a.c. motor, a reluctance motor, or a d.c. motor.
