Abstract

A bag making machine for making bags from a sealable film is disclosed wherein the film is fed over a forming shoulder and around a forming tube. Sealer jaws form a transverse seal to provide a top for one bag and the bottom of the next adjacent bag, and move with the film as it is advanced intermittently along the tube. Separate and independent means are provided to advance the film simultaneously with movement of the sealer jaws, and means are also provided for forming a substantially flat bottom on each bag including a novel arrangement of folding plates for the bottom, tuckers for forming gussets, and creasers for forming creases in the film at the corners of each bag.
