ABSTRACT:
Drive to the sliver feed roll of a fibre-opening unit of an open-end spinner is interrupted by de-activation of a clutch and simultaneously further rotation of the input shaft of a worm and pinion mechanism is blocked against further rotation by release of a spring finger into the path of peripheral teeth on a disc.
Upon a yarn break sensed by a detector, the clutch is de-energized and the spring finger released to arrest and lock the disc.
