Abstract
A forming, filling and sealing machine comprises three sealing mechanisms for heat sealing a film, a folding mechanism for inwardly folding the width direction middle part of the film along the longitudinal direction of the film, and an injection pipe for injecting in filling materials. A first sealing mechanism heat seals a long sheet film to be carried downwards with both side ends overlapped with each other, the heat sealing being applied to the overlapped both side ends along the longitudinal direction of the film. A second sealing mechanism heat seals at least the top of two ridge portions formed by the folding mechanism in the film along the longitudinal direction of the film. A third sealing mechanism is disposed below the injection pipe for horizontally heat sealing the film and cutting the heat sealed portion.
