ABSTRACT:
A dual arbor scrap chopper is disclosed having a number of chopper blades attached to each arbor. The blades are designed to be more easily fitted into a blade recess formed on the arbor, and are preferably designed to provide a blade cutting surface which more closely resembles the optimal elliptical shape without the need for complex cutting patterns. A dual arbor scrap chopper with improved blade performance and ease of blade change-over is provided.
