  • Evacuation system for plastics extrusion
    Patent number: 8282374
    Abstract: Disclosed is an evacuation system for use with plastic extrusion dies, in particular a contaminant evacuation system for removal of air borne contaminants generated at the die orifice of a plastics extrusion apparatus. The system includes an annular evacuation chamber and a suction source connected to the evacuation chamber for generating a vacuum in the evacuation chamber. The evacuation chamber has a radially inwardly directed annular air intake opening for placement about the die orifice, and a baffle structure in the evacuation chamber for equalizing suction pressure along the air intake opening and reduce or avoid localized pressure differences around the extruded product, which would lead to deformation of the product.
    Type: Grant
