ABSTRACT:
A machine for forming, filling and sealing pouches out of continuously fed film material wherein the material forming the pouches extends in a horizontal direction during all steps of the process. Continuous film is fed from a roll thereof with the roll being power driven to prevent stretching of the material as it passes through the various processing stations. The film material can be stamped for marking thereon and can include a header area which is sealed and may or may not have a card placed therein or thereon. The top of the individual pouches may include an aperture therethrough for display mounting or air evacuation. The film then travels to a side sealing device which extends laterally across the moving film for sealing between adjacent pouches. The pouches are loaded with product at a position where immediately thereafter the ends thereof are sealed. At all times the pouch extends in a horizontal position to prevent the weight of the product from interfering with the filling and sealing operations. A movable carriage is included which transports the film in a forward location simultaneously with the roll of film being powered to facilitate release of film therefrom. In this manner the film is transported through the system to maintain the squareness of the formed bags by virtually eliminating stretching or bunching of the traveling material.
