Abstract
A one-screw extruder in which the mechanical thrust function is assigned to a first portion of the screw and of the cylinder, and in which the uniform heating of the material to be extruded is the function of a second portion, thus making it possible for each of the two portions to be specialized and to obtain a better performance of the extruder as a whole.
