ABSTRACT:
An open-end spinning device has a spinning rotor with a rotor pot defining a fiber collection groove therein. A rotor shaft is provided having a diameter between 5.5 mm and 9 mm. Pairs of rotatable supporting rings supported on axles define a nip therebetween. The rotor shaft is rotatably supported in the nip. The supporting rings have a diameter between 62 mm and 82 mm. A thrust imparting device imparts an axial thrust to the rotor shaft in the direction opposite the rotor pot. A non-contacting axial bearing is disposed opposite the free end of the rotor shaft for absorbing the axial thrust without contacting the rotor shaft. The axial thrust imparting device generates an axial thrust between 1N and 7N on the rotor shaft. A driving device contacts the rotor shaft for rotatably driving the rotor and has a contact pressure with the rotor shaft from between 8N and 39N.
