Abstract: Curling of a laminated film is efficiently corrected. The water vapor is brought into contact with the base layer on the outside of the laminated film in a curled state during the first phase transition process. The glass transition temperature of the base layer is lowered. In the base layer, phase transition from the glass state to the rubber state occurs. Supply of the water vapor to the base layer is stopped in the second phase transition process. In the base layer, phase transition from the rubber state to the glass state occurs. The phase transition creates curling that can correct the original curl. The original curl can be corrected by continuously carrying out the first phase transition process and the second phase transition process. The cooling process for cooling the hard coating layer is carried out while the first phase transition process is carried out.
