Abstract
A film feeding device etc. in which, even if film rolls in which tapes are applied to joint between films of the rolls are used, an occurrence of a bag making failure caused by the tape is prevented. A film feeding mechanism (10A) has a receiving member (72) for holding the leading edge of a film (1B) of the standby side and a joining sealer (71) for joining films (1A, 1B). A tape (B) applied to the film (1A) on the use side is detected by a sensor (83), and according to the result of the detection, a cutter (81) cuts of the film (1A) at a portion on the downstream side of the tape. Then, the cut film (1A) and the film (1B) of the standby side are joined by the joining sealer (71), and the two films joined are sent as a long film.
