ã€ Abstract ã€‘ A packaging bag manufacturing device. Among them, the vertical sealing device (3) is composed of a heating roller (31) disposed facing each other across a traveling path of the film and three pressing rollers (41, 41, 42) corresponding to the vertical sealing position. Each of the pressure rollers (41, 41, 42) is connected to a separate pressure adjustment device (48, 48, 48). When the vertical seal is formed, warping of the longitudinal sealing edge of the packaging bag (9) can be prevented by independently adjusting the pressing force of each pressing roller (41, 41, 42).
Sovereignty Item 1. A packaging bag manufacturing device in which an elongated upper film (91) and a lower film (92) are led out in an overlapping state in the same direction, and the transverse sealing device (2) is in the direction of travel of the film. A transverse seal (94) orthogonal to the advancing direction of the film is implemented at equal intervals, and a vertical seal (95) is performed by thermal welding in the advancing direction of the film by the vertical sealing device (3) so as to manufacture a longitudinal seal ( 95) and the portion surrounded by the lateral seal (94) as the packaging bag (9) of the storage portion, the packaging bag (9) can be manufactured in plural rows, and the vertical sealing device (3) is opposed by the traveling path across the film.
