Abstract
There is disclosed a device for preventing a jam of the entrance sizing aperture into a cooling chamber aligned to receive the extrudate derived from an extrusion process apparatus. More specifically, the jam preventing device includes a circular shaped cutter blade pivotally mounted at a point offset from its center and upon detection of an outsized extrudate, driven to sever the extrudate entering the cooling chamber from that already directed therein, to prevent the outsized extrudate from being drawn into the sizing aperture or being driven therein by extruder pressure. The cutter blade is rotatably driven to achieve an extremely rapid cut of the extrudate and includes a cutter support disc whereby the cutter blade may be secured thereto in at least two positions so that a new cutting edge may be presented to the extrudate. Further, the rotating motion of the cutter blade effects a self sharpening action of its cutting edge.
