An apparatus for controlling the driving of an open-end spinning machine whereby driving members such as feed roller, winding roller and draw-off roller are operated at timings optimum for spinning conditions at the time of starting or stopping the machine. Optimum conditions are determined by the amount of yarn wound on a yarn take-up roll of the apparatus.

Apparatus for controlling the driving of an open-end spinning machine

In a spinning frame the fiber feed device for each spinning unit is controlled by a separate clutch interposed between a common drive and each unit. The clutches are disengaged during initial start-up and the yarn ends from a previous operation are returned into the spinning chamber. The clutches are then engaged to feed fibers and the yarns are drawn out and taken up on a spool. A breakage detector is provided for each yarn which controls the clutch for each respective fiber feed.

Method for controlling an open-end spinning frame and an apparatus

A safety device for stopping the bale plucking operation of a bale plucker provided with a detecting device for detecting the existence of metallic substances contained in a fiber bale. The detecting device is disposed at a position along a path of reciprocating movement of the fiber bale back and forth over the working position of a plucking roller of the bale plucker and the driving mechanism of the bale plucker is capable of being instantly stopped by a signal issued from the detecting device upon detection of a metallic substance in the fiber bale so that carrying of the fiber bale to the plucking roller can be prevented.
