ABSTRACT:
Markings for identifying rows of spaced apart tear perforations on rolled paper webs for easy identification of such perforations in low light conditions or by visually handicapped individuals. Identification of the tear perforations allows individual panels or lengths of panels to be torn from the roll along the perforation line so that the panels have a relatively smooth edge and are of the preset size. The identifying markings may be arrows placed at each end of the tear perforation line, contrasting strips superimposed on the perforations which permit clearer sighting of the perforations or other marks. Embossed identifying marks may also be used to allow a visually handicapped or blind person to feel the exact position of the tear perforation end.
