PROBLEM TO BE SOLVED: To improve carrying stability of a film carried with its side ends grasped. SOLUTION: After a flow-cast film is formed by flow-casting dope including a polymer and a solvent on a support, the flow-cast film is removed from the support, whereby a wet film 74 is made. The wet film 74 is transferred to a tenter type dryer having multiple tenter clips 101. Before both side ends of the wet film 74 are grasped with the tenter clips 101, air is blown to a curling part 74a from a blower port 120a of the blower nozzle 120 so that it is held down. The curling part 74a is a schematic planar part 74b even though it does not contact the wet film 74. Therefore, the curling of the wet film 74 is corrected, whereby the wet film 74 is easily grasped with the tenter clips 101 and its carrying stability is improved. COPYRIGHT: (C)2008,JPO&INPIT |
