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