ABSTRACT:
A machine for manufacturing thermoplastic polymers including a plurality of coaxial components adjacent to and made integral with one another, the components forming a longitudinal chamber receiving a pair of interacting shafts having portions correspondingly differentiated to provide sections for feeding and premixing the compound, thus forming a single assembly with coaxial components capable for carrying out full processing of the compound from the raw material to extrusion, without discontinuity of sequence.
