ABSTRACT:
Machine with two generally converging threaded rotors (5) for the extrusion of plastomers, elastomers and the like, comprising a structure (1, 2, 3) supporting a housing (4) containing the rotors (5), a casing (6) containing a pair of reducers (7), a device (11) for generating the movement and devices (10) for synchronized transmission thereof to the two reducers (7), wherein said housing containing the rotors (5) and said casing (6) containing the reducers are rigidly fixed to the support structure (1, 2, 3) and integrally connected together via a housing (8) arranged between the two and containing first means (8a, 8c) for supporting the rotors (5), said rotors being formed in two separate parts (5a, 5b), removably joined to one another, said devices (10) for synchronized transmission of the movement being integral with the bottom part of the said casing (6) and having a high-speed shaft (12) arranged along an axis forming an angle with the axis of the associated rotor (5) and coaxial with the high-speed shaft of the other synchronized transmission device, said high-speed drive shafts (12) being coupled to the first shaft (14) of the respective reducer (7) via a bevel gear (13).
