Abstract: In a bagmaking-and-packaging apparatus, when switching from bagmaking using a first film to bagmaking using a second film, a first impulse sealer interconnects an end-of-bagmaking film of the first film and a starting end scrap of the second film to form a first interconnected film. A second impulse sealer interconnects a third part on a starting end side of the first F1 and a fourth part of the second film to form a second interconnected film.

Abstract: A bag-making and packaging machine includes a bag-making and packaging section and a film supply section. The film supply section includes a film conveyance section that conveys a starting end portion of a replacement film roll supported by a film roll support portion to a bonding portion. The film conveyance section includes a clamping portion that holds a tape adhering to the starting end portion of the replacement film roll, and a pulling mechanism that pulls a second film held by the clamping portion from the replacement film roll. When the replacement film roll is mounted, the film roll support portion rotates the replacement film roll, and the clamping portion holds the tape of the replacement film roll rotated by the film roll support portion.

Abstract: A film roll replacement device supplies a film roll to a bag making and packaging machine. The film roll replacement device includes a holding section, a driving unit, and a controller. The holding section is at least temporarily located adjacent to a supporting shaft to support the film roll in the bag making and packaging machine, and the holding section holds a first film roll supplied to the bag making and packaging machine. The driving unit moves the holding section in an up-down direction. The controller controls an action of the driving unit to move the holding section to a position where a height position of a center of the first film roll held by the holding section is aligned with the height of a center of the supporting shaft of the bag making and packaging machine.
