摘要： An open end yarn spinning apparatus is disclosed which comprises a plurality of side by side spinning positions, with each spinning position including a circular spinning rotor, and aerodynamic bearings rotatably mounting the rotor. A maintenance carriage is adapted to move along one side of the apparatus, and the carriage mounts a cleaning device which may be introduced into the open side of the rotor upon disengagement of its drive means. To prevent the aerodynamic thrust bearing from being damaged during the cleaning operation by reason of the low speed rotation of the rotor, biasing means is provided for applying an axial force to the rotor to axially separate the thrust bearing and thereby avoid undue wear.
