Abstract

Film with a rib along each side edge is widened by gripping each rib with at least two stretching devices at diametrically opposed positions, stretching the film, and moving the stretching devices away from each other. The film is widened without damaging or soiling the surface, so that the quantity of waste material is decreased.
