ABSTRACT:
An ornament plate supplied into a mold is punched out from a continuous sheet by a peripheral knife edge at an end of a press core member and advanced to a place which defines a part of a molding cavity. The press core member has a concave space in the end face thereof surrounded by the knife edge, the area of the concaved space being equal, in developed view, to the plane area of the punched ornament plate. The press core member has applied therethrough vacuum by which the punched ornament plate is attracted to the concave end face of the press core member during injection of molten thermoplastic resin.
