Abstract

An improvement in the object of the main patent number 279,474 which falls on a method for continuously mixing plastic material, characterized in that the machine used for its execution comprises a body having a frustoconical internal cavity provided in the larger diameter tip of an opening for feeding, said feeding opening extending towards the end of the load; a removable closing element having the internal surface in such a way as to constitute practically the continuation of the internal surface of said body, apt to be mounted to close said prolongation of the feeding opening increasing the length of the section useful for the work; a frustum screw, housed inside said cavity, with the larger diameter of the feed side, whose turns determine at least one helical channel of decreasing cross-section from the feed to the discharge, said screw being rotatable inside said cavity so that its boundary development surface with the internal surface of said cavity at least one chamber having, in each section normal to the axis of the screw and measured radially with respect to the screw itself, a variable height between at least a minimum value and at least one value maximum; said frusto-conical body extending with a cylindrical body inside which is mounted a rolling screw also cylindrical integral with said frustoconical screw and at the end of which a discharge opening for the worked material is provided.
