PURPOSE: To completely punch out all moldings in 24-hour continuous operation, without damage of press blades.

CONSTITUTION: In a continuous trimming machine, a thin sheet member 1 processed in a lump by press forming if a continuous molding machine and fed from the machine ia arranged on a hard stage and specified numbers of moldings are punched out in a lump repeatedly out of the thin sheet member 11 by the lowering motion of the vertically movable press blade arranged above the stage. A soft long substrate sheet 25 is put between the thin sheet member 11 and the stage and then the substrate sheet 25 is arranged so as to enable to inch in a specified direction on the stage by a feeding mechanism 26. And the substrate sheet 25 is inched diagonally to make an acccute angle with the feeding direction of the thin sheet member 11.
