ABSTRACT OF THE DISCLOSURE Thermoplastic film is fed from a roll and pleated by passing the film across a series of rigid guides. As the film is drawn down across the guides, the film is pleated and then gathered onto a wind up roll. A J-shaped roll rack is preferably pneumatically activated to bring a fresh roll of film into a position for feeding the pleating arrangement.
