Abstract
Apparatus for applying a pinch mark to a wire (10) at a selected target position along the length of the wire. The apparatus operates in response to a first signal (MARK) indicating that the target position is at a known upstream location. The apparatus includes pinch means (44) including dies (54,56) mounted for movement to and from a pinch station along the wire path. The apparatus includes coupling means responsive to the first signal for causing the dies to move to the pinch station when the target position is at the pinch station. The coupling means may comprise a servo motor (60), control means (70) for driving the servo motor at a selected speed with respect to the wire speed, and engagement means (62,64) responsive to the first signal for coupling the dies to the servo motor such that the dies and the target position arrive at the pinch station at the same time and traveling at the same speed. The dies thereby exert a minimum lengthwise force on the wire. A reset system(66) is provided for returning the dies to a predetermined reset position after each pinch mark is applied. The engagement means may comprise a single revolution clutch.
