Abstract: A method and apparatus for forming a pressure sensitive label on a backing web, wherein at least one "window" area is cut within the label's perimeter but the backing web is not cut. The slug which is cut to form the label's window area is thereafter peeled from the backing web and carried off through a vacuum take-off line for disposal as scrap. At the time of slug removal the pressure sensitive adhesive on the slug and/or the vacuum take-off line is treated with an adhesive-deadening substance to minimize the tendency of the slugs to adhere to one another and to the take-off equipment.
