hub 425 and the cutter hub holder 415 provides a simple means of separating the pelletizer shaft from the cutter hub holder if the cutter hub 445 gets wrapped up with polymer in the cutting chamber 450 the operator can manually pull the pelletizer away from the cutter hub holder 415 causing the retainer ring 420 to compress into groove 401 and disengage from the cutter hub holder 415 which allows the pelletizer to be pulled back from the cutting chamber 450 without damaging any components the cutting assembly including the cutter hub 445 cutter hub holder 415 and drive pins 440 remain in the polymer inside the cutting chamber 450 the operator can then clean out the polymer wrap from the cutting chamber 450 and then reconnect the pelletizer shaft to the cutter hub holder 415 making sure the cutter hub holder 415 gets locked in place by the retainer ring 420 to the disconnect hub 425 to lock the cutting assembly back in place on the pelletizer the pelletizer can then be rolled back into the cutting chamber 450 and restarted a third embodiment of the present invention is shown in fig1 12 12a and 13 the pelletizer generally designated by reference numeral 50 includes a pelletizer shaft 500 with a motion rod 520 coupled to a motor shaft 505 a cutter hub 540 with cutter blades 530.
