PROBLEM TO BE SOLVED: To effectively prevent occurrence of a molding fault and to improve smoothness of a surface of a molding roll, a resin film or the like by activating an oligomer, an additive or the like precipitated on the surface together, and liquefying the surfaces of the both, thereby continuously and uniformly bringing the roll into close contact with the film or the like while improving productivity. SOLUTION: The method for molding a film of a thermoplastic resin or a resin film or the like of a sheet by molding rolls comprises the steps of emitting an ultraviolet or infrared ray to surfaces of the molding rolls and resin film or the like immediately before the film 1 or the like 1 is brought into contact with the rotating rolls 2, 3, thereby activating the rolls and the film or the like, and continuously and uniformly bringing the rolls 1, 3 into close contact with the film or the like. |
