Aufspul- und Dralleinrichtung einer Ringspinn- oder Ringzwirnmaschine sowie Ringspinn- und Ringzwirnverfahren

摘要

The invention relates to a device for producing and winding up yarns in ring spinning and ring twisting frames, wherein the yarn is caused to rotate by a spinner device and is wound up on a cops on the basis of a developing difference in speed relative to the spindle and the cops. The aim of the invention is to drastically increase the yield of said device, to eliminate the friction between ring and rotor, to significantly increase the service life and to reduce the effective forces. Said aim is achieved in that the traditional ring-rotor system is replaced by a rotorless, supraconducting system of magnetic bearing, ring and spinner element.
