ABSTRACT:
A first hemming mold unit (20) and a second hemming mold unit (30), are installed in a single pressing machine. The first hemming mold unit (20) performs partial bending of an edge (95) of a workpiece (93; 96). The workpiece (93; 96), having undergone the partial bending, is transferred to the second hemming mold unit (30), the second hemming mold unit (30) performs remaining necessary bending of the edge of the workpiece (93; 96). Here, predetermined bending of the edge (95) of the workpiece (93; 96) can be completed within the single pressing machine only by downward movement of upper molds (24, 34) of the first and second hemming mold units (20, 30), without having to use a cam and cam driver.
