<p>A C-type frame (37) is movable in a direction in which the C-type frame (37) is adjacent to and away from a workpiece (W) having an outer panel (Wo) and an inner panel (Wi) assembled with each other. After the C-type frame (37) is advanced and a pre-hemming punch (65) is advanced by a swing cylinder (71) provided at the C-type frame (37), a hemming die (35) is raised by a lifter hydraulic cylinder (61) provided on a lower portion (41) of the C-type frame (37) and a flange of the outer panel (Wo) is provisionally hemmed. Then, after retreat of the pre-hemming punch (65) following lowering of the hemming die (35), the hemming die (35) is raised again and final hemming is conducted between the hemming die (35) and the hemming punch (63). <IMAGE></p> |
