A form-fill-seal machine for making a pouch style package is provided, comprising an optional bulge forming station for forming a puff or bulge; a heating and filling station for creating seals and filling the pouch; and an optional flap making station comprising a folding mechanism for folding over a flap and sealing the inside portion of the flap to the front face of the pouch.
Claims8
A form-fill-seal machine for making a pouch style package with a flap that is folded over, comprising:
- a flap making station comprising:
- a reciprocating vacuum bar;
- a reciprocating pressure bar;
- a folder bar;
- and
- a flap folder;
- wherein, in the flap making station, a portion of the pouch is pressed between the reciprocating vacuum bar and the reciprocating pressure bar, the reciprocating vacuum bar draws the pouch beneath the folder bar which folds over a portion of the pouch to form a flap, the flap folder further folds the flap to be adjacent a surface of the pouch, and the flap is pressed against the surface of the pouch between the reciprocating vacuum bar and the flap folder to seal the flap.
