ABSTRACT:
Particulate plastic materials are moved from a supply hopper through a former and formed into a product, the product is cut, and the scrap from the cut product is moved from the cutting area back to the supply hopper by an open conduit pneumatic induction system. The induction system includes a blower and an approximately L-shaped induction conduit with its first leg receiving the exhaust of the blower and its second leg including a Venturi throat. An induction opening is formed in the induction conduit and a scrap feed nozzle is telescopically mounted in the induction opening and has its discharge movably supported in the Venturi throat. The scrap feed nozzle is adjustable with respect to the Venturi throat so as to adjust the system to the most energy efficient position for required operating conditions.
