摘要 |
A method of manufacturing a laminated thermoplastic resin sheet having an improved transparency without generating a wrinkle and an apparatus therefor are provided. The laminated thermoplastic resin sheet is manufactured by using an apparatus comprising an endless belt wound between a first cooling roll (13) having an elastic material (18) and a second cooling roll (14) and a third cooling roll (16) brought into contact with the first cooling roll through the belt (15) , arranging a guide roll (21) near the first roll (13) so as to introduce a molten thermoplastic resin sheet (11) between the first and third cooling rolls (13, 16) in such a manner as to be brought into contact with the belt contact with the first cooling roll and the third cooling roll substantially at the same time, and introducing a thermoplastic resin film (22) between the belt (15) and the third cooling roll (16) through the guide roll (24). <IMAGE> |
