Open-end spinning machine having a plurality of spinning units and a movable servicing apparatus
First Claim
1. An open-end spinning machine having a plurality of spinning units arranged adjacent one another and each containing a spinning rotor assembly formed by a rotor and a shaft, said shaft radially disposed in a wedge-shaped gap formed by a pair of supporting disk means and driven by tangential belt means, said tangential belt means being biased against said shaft by a pressure pulley means during normal operation, comprising:
- servicing apparatus means having brake means capable of being being directly applied to said rotor for stopping said spinning rotor assembly; and
securing means operable separately from said brake means for securing said spinning rotor assembly in an operating position when said belt means is disengaged from said shaft, wherein said securing means includes means selectively movable from an inoperable position to an operable position in engagement with the rotor shaft.

Abstract
An open-end spinning machine is provided having a servicing apparatus that can be moved along a series of spinning units, each unit containing one spinning rotor assembly comprising a shaft and a rotor. It is provided that in the individual spinning units, the shafts of the spinning rotor assemblies are disposed in wedge-shaped gaps formed by pairs of supporting disks and the shafts are driven by a tangential belt. The servicing apparatus contains a brake that can be applied to the rotor when servicing of a unit is required. The rotor is stopped while, at the same time, the drive of the tangential belt is interrupted via a bracket pulley that can be moved away from its operating position. In addition, members are provided for securing the spinning rotor in its operating position during the braking.
