<p>PURPOSE:To smoothly release a film and an anti-sticking tape before the film reaches the next process and to efficiently perform heat-sealing, by providing a tape moving device for moving the anti-sticking tape between the film and a heat sealer in synchronous relation to said film. CONSTITUTION:A sprocket 15 is rotated by a film feed drive source 7 through a chain 8 in order to allow an upper anti-sticking sealing tape 6 to be synchronous to the intermittent feed of a film 1 between the film 1 and an upper heat sealer 3 and said sealing tape 6 moves in an endless state at the same speed as the film 1 by a nip roller 10, a swing roller 11 and guide rollers 12, 9. At the same time when films are mutually sealed at a heat-sealing part, the anti- sticking tape 6 moving in synchronous relation to the film 1 becomes a sticking state along with the film 1. At this time, it a cooling apparatus is arranged in succession to the head-sealing part, the film and the anti-sticking tape are rapidly and sufficiently cooled and can be brought to a smoothly releasable state before reaching the next process.</p> |
