METHOD FOR OPENING CYLINDRICAL FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for opening a cylindrical film which can easily open the cylindrical film without causing the problems of the occurrence of a suction trace in the cylindrical film made of a thermoplastic resin or a thermoplastic elastomer composition and the hanging-down of the end of the film. SOLUTION: In the method for opening the cylindrical film 1, at least one end 1 m of the cylindrical film 1 folded in the shape of a plane which is made of the thermoplastic resin or the thermoplastic elastomer composition is opened. By making an adhesive member 2 contact a plurality of spots in the periphery of the peripheral surface of at least one end 1 m of the cylindrical film 1 folded in the shape of a plane, the one end 1 m is held by its adhesion. Next, the adhesive member 2 with its one end 1 m held is moved to open the one end 1 m of the cylindrical film 1 cylindrically. COPYRIGHT: (C)2010,JPO&INPIT
