<p>A form-fill-seal machine is adapted to manufacture a bag having a gusset section, and includes a conveying part, a plurality of splitters and an inward-folding member. The conveying part is configured and arranged to convey a tubular packaging material. The splitters extend along a conveyance direction of the tubular packaging material to contact with the tubular packaging material from an interior side. The inward-folding member has a pressing part including a plurality of contacting portions that are three-dimensionally arranged to generally correspond to a shape of the gusset section. The inward-folding member is configured and arranged to press the contacting portions of the pressing part from an external side of the tubular packaging material against an outer surface of a gusset formation area of the tubular packaging material located between the splitters to form the gusset section.</p> |
