Abstract
A thread rolling machine in which the dies are monitored for a mismatch condition by a proximity sensor responsive to displacement of the moveable die in a direction parallel to the axis of the workpiece. This displacement, which occurs when a mismatch condition exists, is permitted by the running clearances in the slide carrying the moveable die. When more than a negligible displacement occurs, corrective action can be taken to reject out of specification workpieces and to adjust the relative positions of the dies to maintain them in a matched condition.
