A web of pressure sensitive adhesive label material is releasably attached to a paper carrier web, and the combined webs are continuously fed through a label printer and die cutter, and a scrap lattice web of the label material is continuously separated from the carrier web. The lattice web with adhesive on one side is directed into a curling and pneumatic conveyor apparatus. The apparatus includes a condensing member or curling cone with a converging wall having a rough low friction inner surface which curls, folds and collapses the scrapped lattice web into a rope-like mass or body which is pulled by suction air flowing inwardly through an air inlet surrounding the body. The suction air pulls the body into the center portion of a pneumatic conveyor duct to provide for conveying the rope-like body for a substantial distance to a remotely located waste receptacle.
A method of continuously removing and conveying a scrap lattice web of material having adhesive on one side and separated from die-cut pressure sensitive labels releasably attached to a carrier web, said method comprising the steps of directing the lattice web into an inlet of a condensing member, progressively condensing the lattice web with the condensing member into a continuous rope-like body of material with the adhesive holding the body together, directing the body from an outlet of the condensing member into an inlet of a pneumatic conveyor duct, and directing air flow into the inlet of the duct around the body of material for spacing the body of material from an inner surface of the duct while conveying the body through the duct.
