Abstract (en)
A new method of making a form fill bag having a reclosable fastener thereon and a mechanism therefor wherein a continuous length of film (10) is advanced and joined first and second fastener profile strips (16) are laid laterally onto the film of a length substantially equal to one-half of the film width, the film is advanced and formed into a tube with the side edges folded together and seamed, the first profile strip is attached to the surface of the film prior to forming it into the tube and the second opposed interlocked profile strip is attached to the inner surface of the film after it is formed into a tube, and a cross-seam is formed in the tube above the closure strip to form the bottom of the succeeding bag and a completed bag is cut from the film by cutting below the bottom seam and above the fastener strips.
