METHOD FOR MANUFACTURING COATED FILM

A coated film having good characteristics is manufactured. A method for manufacturing the coated film includes: (a) a step of applying a coating liquid to a first surface of a base material unwound from an unwinding unit UW; (b) a step of forming a coating layer on the first surface of the base material by drying the coating liquid (coating film ) on the base material ; and (c) a step of winding the base material on which the coating layer has been formed in a winding unit WD. Also, the base material is continuously arranged from the unwinding unit UW to the winding unit WD, tension cut of the base material is performed by a first suction roll SR after the base material is taken out from the unwinding unit UW and before the step (b), and tension cut of the base material on which the coating layer has been formed is performed by a second suction roll SR before the step (c).
