A method of stably forming a film of a molten resin by extrusion lamination, preventing the swinging of the film and excess of necking during the extrusion lamination, increasing a width of film in the flat portion, increasing the yield of product and improving the intimate adhesion onto the base member. Namely, the method of producing an extrusion-laminated member (7) by extruding a thermoplastic resin from a T-die (2) into the form of a film (1) and laminating the film on a metallic base member (3) using laminating rolls (6a,6b), wherein a pre-roll (5) is disposed between the T-die (2) and the laminating roll to receive the film on the side opposite to the side that adheres onto the base member (3) over the whole width of the film, the film received by the pre-roll (5) is fed to the laminating rolls, conveyed by being supported by the laminating rolls (6a,6b) on the side opposite to the side that adheres onto the base member (3) and is fed to a nipping position so as to be melt-adhered onto the heated metal blank. <IMAGE> |
