ABSTRACT:
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.
