Abstract
Abstract An electronic component lead cutting and clinching mechanism having means for operating substantially simultaneously on a plurality of aligned leads. The cutting edges are angularly oriented to align with the component leads and raised to a position adjacent the undersurface of the wiring board into which the component leads have been inserted. Pneumatic cylinders actuate the mechanism.
