A high production multiple station endforming machine mounts a plurality of work stations upon an indexable rotary head whereby rotation of the head permits the work stations to be indexed between loading, operational and unloading positions. The workpieces are locked in jaw members operated by an over-center linkage wherein the position of the linkage is controlled by expansible chamber motors.
