Abstract
A vertical bag-making/filling/packaging machine includes: a top folding portion which forms a first fold by folding one of sides of a band-shaped film into a Z shape; a bottom folding portion which folds a center of the film so that side edges of the film face each other; a first pleat guide which pulls a first pleat of the first fold upright; a spout portion-forming portion which forms a spout portion between the side edges of the film; and a second pleat seal portion which forms a second pleat by heat-welding the side edges of the film together so as to make the film into a tube shape.
