Abstract

An extruder cylinder is provided with is not 2 consecutive stoppered openings any of which can be fitted with the charing hopper to effectively alter the length of the screw. Pref. the other parts can be used as vents or to add other components, also the plasticiser screw can be interchanged for one which is threaded only to the required position of the hopper.
