Abstract
A method of manufacturing a laminated body consisting of a synthetic resin member provided with a layer member thereon, in which the member is bent to cover the edges of the resin member. The method includes the compression, resulting from a male mold and a female mold approaching each other, of the layer member and molten resin. The female mold has flanges mounted on its edges to permit the layer member to cover the edges of the resin during compression. Molten resin materials are supplied between the male and female molds prior to subsequent to the compression.

A method of manufacturing a laminated body consisting of a thermoplastic resin provided with a layer member thereon by press molding, comprising the following continuous steps of:
- arranging said layer member on a slidable frame attached to the sides of a male mold and providing a female mold having flanges mounted thereon;
- holding a periphery of said layer member by closing said female mold and said flanges against said slidable frame and said male mold and shifting said flanges to the inside of the cavity of said female mold at least at the time of said closing;
- preforming said layer member by approaching the molds toward each other after closing;
- supplying, at any time from said holding and prior to the forming or shaping, molten resin between said layer member and said male mold;
- forming or shaping said layer member and said molten resin to cover the face of a resin body being formed or shaped from said molten resin with said layer member and to form a bend of said layer member for lapping all end portions of the formed or shaped molten resin by approaching said female mold and said flanges against said male mold and slidable frame so as to form or shape said laminated body.
A method of manufacturing a laminated body consisting of a thermoplastic resin provided with a layer member thereon by press molding, comprising the following continuous steps of:
