Abstract
A vertical bag-making/filling/packaging machine (1) includes: a top folding portion (20) which forms a first fold (F1) by folding a side of a band-shaped film (F) into a Z-shape; a bottom folding portion (30) which forms a second fold (F5) by folding a center of the film (F) into an M-shape; a top seal portion (40) which forms a top gusset (G3) and a spout portion (G7) protruding from the top gusset (G3) by heat-welding the first fold (F1) and side edges (E1 and E2) of the film (F) so as to make the film (F) into a tube shape; and a bottom-seal portion (50) which forms a bottom gusset (G4) by heat-welding the second fold (F5).
