The value of the rolling torque is measured t each frame (1£2, 1i, 1n) through which a metal product (b) passes, and the measurement is performed at the moment when said product reaches the following frame ,at which point the frame at which the measurement is performed is switched over to torque regulation. The last frame reached by the product remains in speed regulation and it acts as a controlling frame for all other frames situated upstream there from so as to enable them to conserve torque equal to there respective reference torques by adapting their speeds. Once the reference torque adapting their speeds. Once the reference torque measurements have been stored in the control system (2,3), regulation is obtained by making use of a distribution key for the stresses between the frames. Drawing: 1 Sheet.
