Abstract
An improved underwater pelletizer adapted to prevent extruded material from agglomerating in an pelletizing assembly, which pelletizer includes a cutting assembly having (1) a shroud fixedly mounted to the surface of the recess in the center of the die ring thereby preventing pellets from being trapped between the die face and the cutting assembly; and (2) novel knives contoured to conform in their angular positions to the curvature of the shroud.
