Abstract:
A venturi inducer system adapted for transferring a continuous supply of material including trim waste from a papermaking or converting process, said system comprising an elongated tubular intake duct having a center axis and adapted to receive the material, a housing surrounding said intake duct and cooperating to define a generally annular chamber therebetween, said housing having a tapered annular portion cooperating with an inner end of said intake duct to define a generally annular nozzle opening, said housing chamber having an air inlet adapted for receiving pressurized air from a source, a tubular outlet duct connected to said housing for receiving pressurized air flowing through said nozzle opening, said pressurized air flowing through said nozzle opening forming a venturi effective to induce a suction air flow in said intake duct for pulling the material through said intake duct and for blowing the material into said outlet duct, and a plurality of adjustable members connected to said intake duct and operable to adjust said inner end of said intake duct axially within said housing for precisely adjusting the area of said nozzle opening to adjust the flow rate of air through said nozzle opening.
