METHOD FOR MANUFACTURING LONG LAMINATED FILM

摘要

Provided is a method for manufacturing a long laminated film which has a uniform coating layer by suppressing wrinkles generated on a coated surface of a base film that is a long film. The traveling long film is supported using a first guide roll and a second guide roll, and the long film is allowed to travel while pinching film portions at both width-direction ends of the long film using a pair of nip rolls and the guide roll so that the coating layer is formed by applying a coating material. An outer diameter of both end portions of the guide roll disposed oppositely to the pair of nip rolls is larger than an outer diameter of a central portion that is not both end portions.
