Method for producing a laminated thermoplastic resin film, a laminated thermoplastic resin film and a thermally produced molding of the same

摘要

A first thermoplastic resin film is laid on a heated endless belt to be moved together with the endless metal belt, a second thermoplastic resin film is superposed on the first thermoplastic resin film laid on the belt, and the first and second thermoplastic resin films laid on the belt are touch-rolled by a combination of the belt and a second roller to be laminated. The second thermoplastic resin film can be superposed on the first thermoplastic resin film laid on the belt after being touched to the second roller. A thermally produced molding is obtained by heat treating the laminated thermoplastic resin film.
