Abstract
The pelletizer comprises a chamber having a first side and a second side coupled to an extruder. A shaft extends through the first side into the chamber, a rotatable cutter assembly is mounted to the end of the shaft in the chamber and a die assembly is mounted at the second side of the chamber and has a die face facing into the chamber. The cutter assembly is positioned for rotation adjacent the die face. A prime mover is coupled to the shaft for rotating the cutter assembly. Plastic material is extruded through holes in the die assembly into the chamber as the cutter assembly is rotated to cut plastic streams coming out of the die assembly into pellets. A position control assembly automatically controls the position of the cutter assembly adjacent the die face. The cutter assembly has a plurality of cutting blades mounted thereon. Each cutting blade has a generally flat mounting portion for mounting to a hub, an elongate blade support portion extending upwardly from the mounting portion and a blade portion extending laterally angularly outwardly from the blade support portion and having a blade edge defined between a first blade surface extending generally parallel to and spaced …
