Abstract: A continuous supply of scrap material from a papermaking or converting process is transferred by a venturi inducer system including a housing surrounding a tubular intake duct which defines with the housing an annular air chamber connected to receive pressurized air from a motor driven blower. The housing has a tapered or frusto-conical portion connected to a tapered material outlet duct and which cooperates with the inner end of the intake duct to define an annular nozzle opening. Long adjustable bolts connect the intake duct to the housing outboard of the housing and provide for externally adjusting the intake duct axially for precisely selecting the area of the nozzle opening to optimize the air flow through the nozzle opening for pulling and transferring the material while minimizing the electrical power required to operate the blower motor.

Abstract: 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.
