Abstract

The present invention relates to a bag making machine (20, 30) comprising: a conveyor part (37) for conveying a multi-ply film (S) obtained by overlapping films (13a, 13b); a side edge sealing device (27) for thermally fusing the films (13a, 13b) together; and an ultrasonic device (26) for flattening a portion of a chuck member (14) disposed between the films (13a, 13b). The side edge sealing device (27) has a platform (44) and a heat-generating head (45). The ultrasonic device (26) has an anvil (41) and an ultrasonic horn head (42). The heat-generating head (45) and ultrasonic horn head (42) are linked by a linking member (51) and reciprocally moved at the same period.

Description

technical field [0001] The present invention relates to a bag making machine and a bag making method using the bag making machine. This application claims priority based on Japanese Patent Application No. 2019-125859 filed in Japan on July 5, 2019, and the content thereof is incorporated herein. Background technique [0002] There is known a pouch with a chuck in which an opening can be opened and closed by a chuck member formed inside the pouch after an end seal is unsealed. When manufacturing such a pouch with a chuck, after arranging the chuck member between two resin films and joining the chuck member to the resin film along the longitudinal direction, the peripheral portion of the pouch is The two resin films are thermally welded to each other. [0003] However, when thermally welding the peripheral part of the bag, there is a portion where both ends of the chuck member overlap on the peripheral part. Since the thickness of the chuck member is thick at such a locatio...
