PURPOSE: To eliminate a scrap in case of end cutting, and to improve the yield by bringing a long-sized metallic plate to end cutting by a trimming/bending press in an area of an elastic deformation, and thereafter, separating a connecting part together with bending.

CONSTITUTION: A long-sized metallic plate 1 is fed to an upper die trimming/ bending punch 8 after a working hole 2 and a stopping hole 3 have been pro vided through it. In the punch 8, a lower die trimming die 7 and cutters 9A, 9B work together, and by trimming/bending, an end cut part 4 is formed. This working is executed in an elastic deformation area, therefore, a twisting deforma tion is recovered elastically. Subsequently, the metallic plate 1 is cut from a connecting part 5 together with bending, and a prescribed work 12 is formed. Accordingly, in case of end cutting, no scrap is generated, and the yield can be improved.
