Abstract
A process for the formation of a laminated body consisting of an upper layer member which covers a hardened synthetic resin is disclosed. The process includes the compression, resulting from a female mold and a male mold approaching each other, of the layer member and molten resins. The final engagement of the molds permits the cutting of the layer member so as to form or shape the ultimate 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:
- arranging said layer member on a slidable frame surrounding a male mold;
- holding a periphery of said layer member by closing a female mold against said slidable frame;
- preforming said layer member by approaching said female mold in contact with said slidable frame toward said male mold;
- supplying, at any time from said holding and prior to cutting, molten resin between said male mold and said female mold;
- forming or shaping said layer member and said molten resin by compression resulting from said female mold approaching said male mold;
- cutting, prior to or simultaneous with the completion of said forming or shaping, said layer member by engagement of the inner edges of said female mold with the outer edges of said male mold so as to form or shape said laminated body, wherein a width of clearance between inner edges of the female mold and outer edges of the male mold during said step of cutting is from 0.01 to 0.2 mm.
