ABSTRACT:
A die plate for an extruder is coupled directly to a fluid-driven motor on one side and to an extruder on the other side. Suitable fluid inlet and outlet passages are formed in the die plate to supply the motor with fluid and withdraw fluid. A cutter assembly includes a housing to receive the motor within and is coupled for rotation to an output shaft from the motor, so that in use blades mounted on the housing are caused to rotate into the path of extrudate and to sever it.
