       Roll torque can be estimated from the rolling force. Torque is equal to force multiplied by the radius at which the force acts. We can assume that the roll force is acting perpendicular to the strip at a radius equal to one half of the projected arc lengt h of contact. For each roll the torque is T = FL/2 Roll power is given by
