ABSTRACT:
A metal measurement plate (5), having a size suitable for being placed between the set of upper rolls and the set of lower rolls of the leveler, has positioning means (60, 61, 62) for positioning it with respect to the rolls in the leveling direction, and strain gauges (51) for measuring elastic deformations of the plate during clamping on the leveler, said strain gauges being fastened to the plate so as to form several transverse rows of gauges (51to56) each located vertically in line with one of said rolls, on the opposite face of the plate with respect to said roll.
