ABSTRACT:
In a method and molding apparatus for laminated molded bodies, a thermal-molding felt and a thermoplastic resin sheet, respectively in hot and soft condition, are set or placed on a mold face of a cold-pressing-molding lower mold. A cold-pressing-molding upper mold lowers onto the lower mold to press the thermal-molding felt and the thermoplastic resin sheet. Simultaneously, cooling air is supplied to center portion of the thermal-molding felt through a blowing pipe protruding from mold face of the thermal-molding felt side and intruding into the felt accelerating circulation of cooling air and cooling of the thermoplastic resin sheet.
