Abstract

Apparatus for the high speed manufacture of elongated tubular film products from lengths of flexible, flat films. Film is unspooled, passed over a forming collar, and onto a tube. On the tube, the film has a circular cross-section, with overlapped edges. A
sizing ring correctly sizes the overlap. The film is immediately fed into a heating unit, where a closed-loop band contacts the overlap and heats the film to form a sealed seam. The film is advanced through the heating unit by boggie mounted drive belts. From the heating unit, the film is advanced into accumulation adjacent a casing brake.
