ABSTRACT:
A wiredrawing machine (10) consists of a plurality of stages (11) in cascade, each stage comprising a drawbench (13) for passage of the wire (14) partially passed over a power-driven traction pulley (12). The traction pulley is kinematically connected for operation to a first gear (17) having a power-driven planetary gear (19) meshing therewith and rotating about the first gear (17) periphery. Sensor means (23) detects the angular position of the planetary gear (19) about the axis of the first gear (17) and sends position signals to a control circuit (24) which in turn sends commands for speed adjustment to motor (16), in terms of keeping the planetary gear at predetermined angular positions about the first gear.
