APPARATUS AND METHODS FOR CONTINUOUS EXTRUSION Abstract of the Disclosure Two rotors cooperate to advance a rod of indefinite length continuously into an extrusion die. Portions of radially extending surfaces of the two rotors are utilized to grip the rod therebetween, in order to effect such advance of the workpiece rod upon the simultaneous rotation of the two rotors. An annular groove extends along the appropriate radially extending surface of one of the rotors. Such annular groove serves to retain the rod therein while guiding the rod along a path leading to the die. The face-to-face arrangement of the two rotors along their respective radially extending surfaces permits a very high extrusion pressure to be supported, while also allowing effective sealing of the annular groove at such very high extrusion pressure. - i -
