Abstract
A system that enables a cutter head to pivot for improved alignment with a cutting face or die is disclosed. The system includes a cutter hub and a driveshaft hub mated with a plurality of round, spherical, or ovoid surfaces to enable the cutter hub to pivot with respect to the driveshaft hub. The system can include a plurality of alignment pins with spherical surfaces to transfer torque from the driveshaft hub to the cutter hub. The system can also include a cutter head, which can include a plurality of cutting blades. The system can be used in cutting machinery, such as a pelletizer, where alignment of the cutting head and the cutting die (or other cutting surface) is desirable.
