ABSTRACT:
An extruder assembly has a gear box drivable by a motor, an output shaft having a main portion extending through the gear box and rotatable by operation of the motor and gear box, and an extruder housing located forwardly of the gear box. The output shaft has a further portion extending forwardly from the main portion and passing into the extruder housing and having a screw configuration therein for feeding plastic material through the housing when the output shaft is rotated. The main portion of the output shaft is axially slidable in the gear box, and the forwardly extending portion has a diameter not greater than the diameter of the main portion whereby the output shaft can be withdrawn from the housing and the gear box by rearward movement therethrough. A retainer is operable to retain the output shaft in an operative position for rotation to feed plastic material through the housing and also to permit the output shaft to be withdrawn by rearward movement when desired.
