The process utilizes a shaft (2) supporting the stator (1) and/or the rotor, respectively, and capable of rotating around its axis, a first (3) and a second (3′) working station allocated on an opposite position on the sides of the stator and/or the rotor, respectively, next to the outlet area of the lateral mouth of a cavity. Said stations have carrying devices (4, 4′) for the leading wire (f), clamps (5, 5′) capable of grasping and moving the tip of the wire (f), and sensors (6, 6′) for detecting the arrival of the extremity of the wire (f). The tip of the wire is at first introduced, by the clamp (5) of one station, inside the nearby carrier (4) and passes into the nearby cavity, and then exits until it is detected by the sensor (6′) of the other station, whereupon the tip of the wire is grasped by the other clamp (5′) and reintroduced into the second carrier (4′), as soon as the wire has exhausted its run inside the first cavity and the supporting shaft has, after rotating, positioned the subsequent cavity opposite the second carrier.
