Abstract
A method and apparatus for applying a reclosable profile element, or zipper, to a packaging film. The packaging film is formed into a tubular form about a forming tube. The zipper is received in a guide block formed along the interior of the forming tube. The extended flanges of each member of the zipper are urged flat against the outer circumference of the fill tube. The packaging film is applied over the flanges of the zipper and a header is created by a rod extending along the length of an initial portion of the fill tube. A heated seal bar secures the film to the flanges of the zipper. After the zipper has been attached to the film, the packaging material is urged out of the interior of the fill tube by a changing configuration of the guide block.
