Abstract
A method and apparatus for forming and sealing bags in a continuous or intermittent manner where the bags can be filled during the forming operation. Specifically, there is disclosed an apparatus for supplying a sheet or film of bag material to a mechanism for forming the sheet into a tube having overlapping edges in a longitudinal direction. A series of plates are arranged in the forming apparatus for applying adhesive in spaced lines or strips on opposed surfaces of the overlapping edges. After the adhesive is applied in this manner the opposed surfaces of the overlapped edges are pressed together to seal the edges. The tube is sealed in a transverse direction at the bottom, filled in a conventional manner, sealed in a transverse direction at the top, and then cut to form the bag filled with food or other material, ready for distribution and sale.
