Winding and twisting device of a ring spinning or ring twisting machine as well as ring spinning and ring twisting method

Abstract

The present invention provides a winding and twisting device of a ring spinning or ring twisting machine with at least one stator, which comprises at least one superconducting material and a stator cooling system, at least one rotor that creates a magnetic field, and a rotatable spindle, wherein the rotor and the stator are arranged co-axially to the spindle; and wherein the rotor and the stator are formed in a way that a ring-shaped air gap, which is arranged co-axially to the spindle and in which the thread to be wound up can circulate, is formed between the rotor and the stator. Furthermore, a ring spinning or ring twisting method, in which fiber material is twisted and subsequently wound up, is provided, in which such a winding and twisting device is used, wherein the rotor is held co-axially at a distance to the stator by a rotor holding device, wherein the temperature of the superconducting material of the stator is reduced below the transition temperature of the superconducting material and wherein the rotor is released by the rotor holding device.
