Abstract
A cutter hub and blade assembly for cutting polymer strands extruded from a die face in a pelletizer has cutter blades mounted on the cutter hub at a steep angle. The blades are beveled along a portion of their leading edge to form a blunt cutting edge or surface to the blades which is generally perpendicular to the die face. By beveling the leading edge of a blade supported at a steep angle to form a blunt cutting edge, the bottom surface area of the blade in contact with the die face can be significantly reduced. The reduced contact area provides several advantages including a clean cut of the pellets and a faster blade grinding when seating the blades to the die face.
