Abstract
A method and apparatus for forming plastic bags with zipper profile thereon, in situ, on a form and fill machine. Plastic film sheeting containing profiles is moved over a forming collar disposed about the filling spout of the machine. A major portion of the film is formed into a tube about the spout while a minor portion of the film, including the profiles, is directed away from the spout. After the tube is formed and filled, the major and minor portions are brought into alignment and transverse seams are formed on opposite sides of the product to form the bag.
