Abstract
An improved technique for stopping the advance of spun yarn through the draw-off rollers and distributing cylinder of an open-end spinning machine in response to a detected yarn breakage condition is described. A reversible clutch is selectively interposed between first and second oppositely rotating drive shafts and the cylinder, which in turn is coupled to the draw-off rollers. The clutch is operated from a normal forward advance condition to an operated reverse condition for a duration corresponding to a variable-duration control pulse generated in response to a yarn breakage condition upstream of the discharge end of the machine withdrawal tube. The duration of the control pulse is adjusted to dynamically brake the forward motion of the advancing yarn to a stop. The control pulse is removed soon enough to prevent reverse movement of the yarn.
