UNWINDING DEVICE OF LONG-SIZE RESIN FILM, SURFACE TREATMENT DEVICE AND MANUFACTURING METHOD OF RESIN FILM WITH METALLIC FILM

摘要

PROBLEM TO BE SOLVED: To provide an unwinding device of a long-size resin film, a surface treatment device and a manufacturing method of a resin film with a metallic film capable of efficiently eliminating static electricity due to peeling electrification between a long-size resin film F unwound from an unwinding roll 52 disposed in a decompression chamber and a long-size resin film wound on the unwinding roll.;SOLUTION: An unwinding device of a long-size resin film includes a gas blow-out means for blowing gas against a film peeling part provided on a peeling surface side space part 81 of a film peeling part 80 in which long size resin film is unwound from an unwinding roller and is constituted with a plurality of gas blow-out port groups or a single long-size gas blow-out port provided along the width direction of such a long-size resin film that the gas blow-out port 70 of the gas blow-out means is unwound such that static electricity due to peeling electrification between the long-size resin film unwound from the unwinding roll and the long-size resin film wound onto the unwinding roll is eliminated.;COPYRIGHT: (C)2016,JPO&INPIT
