摘要

PROBLEM TO BE SOLVED: To increase a winding speed of a film by removing a crease generated in a width direction of the film while proper tension is made to be imparted to the film.;SOLUTION: The device for removing the crease of the film comprises: a first member 61 on which a belt-like film 11 which moves in a longitudinal direction is wound around; a second member 62 which sandwiches the film together with the first member; an air hole 62d formed in the second member; and an air blowing means in which the belt-like film is pushed against the first member by blowing air from the air hole on the belt-like film. The first member is made up of a columnar member in which the cross section forms a round shape and which is unable to rotate, or a rod-like member in which the cross section is semicircular or fan-shaped, and the second member is provided with a cover part 62a which has an inner surface curved in a semicircular shape in the cross section. The device for winding the film comprises: a feed section 12 sending out the film; a winding part 13 winding up the film sent out from the feed section; a plurality of carrier rollers 16 to 19 provided in a film carrier path between the feed section and the winding part; and the device for removing the crease 60.;COPYRIGHT: (C)2014,JPO&INPIT
