Abstract

PURPOSE: To simultaneously perform adhesion and trimming of a given composite resin sheet, an intermediate sheet, and an outer layer material, by a method wherein said materials are placed between particular upper and lower molds in which a positioning groove and a groove along a trimming line are provided, respectively, and they are press-molded thereat.
CONSTITUTION: A concave groove 3, whose cross section is rectangular, is formed in a lower mold 1 along a trimming line surrounding a molding surface 1a thereof, while a positioning groove 4, whose cross section is arc is provided in an upper mold 2 at a position where the groove 4 faces against the groove 3. The outer circumference of the groove 3 in the lower mold 1 is lowered by one stage, whereby a clearance, being formed between the lower and the upper mold when the molds are locked, is enlarged. A polypropylelen composite resin sheet 6 (which is formed with polypropylene mixed with fine saw dust as a filler for molding), which is preheated to near a melting point, is set on the lower mold 1 with said molds unlocked, an intermediate member 5 being placed thereon. An outer layer material 7 is further laid thereon, the lamination being then press-molded.
