摘要：
A multilayer molded article having a thermoplastic resin body and a skin material covering the resin body is produced by supplying a skin material between a pair of molds, holding the skin material between a skin material-holding frame which is moved in a direction perpendicular to a mold-closing direction and a skin material-supporting frame which is moved in the mold-closing direction, supplying a mass of a thermoplastic resin melt, and closing the molds to form a multilayer molded article, in which at least one moving member which moves forward or rearward in the mold closing direction is provided around a mold face and is recessed in the mold closing direction after the supply of the resin melt, at least one ejector which is provided on the skin material-holding frame is ejected to fold an edge of the skin material towards a center of the mold, and the moving member is forwarded toward the mold face so as to fold back the edge of the skin material over the back of the resin body.
