ABSTRACT:
An improvement in a roving stop motion for a spinning machine of the type having a series of pairs of drafting rollers, the stop motion including a clamping member mounted on a lever arm drivenly connected to an actuating rod by a carriage which is selectively mountable at differing locations along the actuating rod. The actuating rod is responsive to roving breakage to drive the lever arm to cause the clamping member to separate the feed rollers from one another and press the roving against one roller. The positionability of the carriage enables the lever arm to be properly disposed with respect to the feed rollers when the spacing between the roller pairs is varied.
