<p>PROBLEM TO BE SOLVED: To provide a lamination device in which generation of a curl can be prevented when films different in elastic modulus are stuck to each other and to provide a method for producing a multilayer film.SOLUTION: The lamination device is constituted so that an endless metallic belt 12 is hung over between a first heat roll 6 and a first nip roll 8, a second heat roll 5 is disposed on the opposite side of the first heat roll 6 while interposing the endless metallic belt 12 therebetween, a second nip roll 7 is disposed on the opposite side of the first nip roll 8 while interposing the endless metallic belt 12 therebetween, the first film 1 of a long shape is supplied to the space between the endless metallic belt 12 and the second heat roll 5, and the second film is layered on the first film 1 in such a portion that the first and second nip rolls 8, 7 are opposed to each other. When the endless metallic belt 12 is viewed from the outside thereof in the width direction, a portion of the endless metallic belt 12, which portion is located from a position between the first and second heat rolls 6, 5 to another position between the first and second nip rolls 8, 7, is extended in a straight line.</p> |
