ABSTRACT:
A plastic pellet delivery system including an extruder nozzle having an orifice and an arcuate surface adjacent the orifice and rigid cutting knife which is eccentrically mounted on a shaft that is positioned and is rotated adjacent the orifice to move the rigid knife eccentrically into and out of engagement with the nozzle surface. The cutting knife is mounted for limited yielding pivotal movement relative to the eccentric mount such that it will deflect angularly with respect to the eccentric mount as it is engaging the nozzle surface such that the free edge of the knife blade tip is moved radially inwardly as the eccentric mount is rotated providing a substantially constant force of the blade against the nozzle surface.
