PROBLEM TO BE SOLVED: To automatically replace a film, even in the film unjoinable since a coating layer is arranged on one surface. SOLUTION: A paper strip-like joining film is made by cutting the distal end of a belt-like film 3b for joining over the whole width, and the rear end of a belt-like film 3a supplied to a packing machine and the front end of a preliminary film are set in a butting state, and are arranged so as to straddle both films while facing a sealable non-coated surface by reversing the joining film. Next, the film is joined by sandwiching an end part of both films and the joining film by a seal device 31, and thermally sealing by heating. COPYRIGHT: (C)2011,JPO&INPIT |
