Abstract (en)
A press (20) with both prehemming and final hemming tools or steels (22, 24) each driven by the same prime mover (44). Each steel is mounted on a separate carrier (36, 38) driven through separate toggle joints (40, 42) to advance and retract the steels (22, 24) for prehemming and final hemming of an upturned flange (26) along the edge of a steel panel (30). To facilitate synchronizing the operation of at least two presses (20), the prime mover (44) may be a screw and servo motor drive assembly (158). <IMAGE>
