Abstract (en)

The rolling machine for forming a threading on a cylindrical body, comprising two or more forming rollers (6), each provided with a threading (8) having at least one thread extending around its rotation axis (Z), and adapted to plastically deform a cylindrical body available along a central working axis (A) of the machine (1). The machine therefore comprises two or more actuator means (15) each provided with a movable head on which a corresponding forming roller (6) is mounted to move it along a respective first transverse axis (R) perpendicular to the working axis (A), and two or more sensor means (30), each of which is fixedly mounted on the movable head to detect the distance of the thread profile of the corresponding forming roller (6) generating corresponding measurement signals. A logic control unit, in communication with the sensor means (30), receives measurement signals of the sensor means (30) and defines the relative position of the threads of the forming rollers (6).
