Abstract
A roller leveler is provided with mechanisms to continuously sense and to measure roller deflection and to automatically correct the deflection based on the degree of deflection sensed. The sensing mechanisms are mounted on a structure which is isolated from the forces of deflection acting on the rollers and may comprise mechanical, electromechanical, electronic, sonar, optic, fiber optic, fluid, or laser devices. Novel back-up rolls are also provided to correct the deflection.
