A process and apparatus for on-line measurement of unflatness of hot or cold rolled strip products wherein the longidudinal bending of a shape roll over which the strip passes provides a measure of the unflatness of the strip. Actual values of force dis-, placement or bending moment near the ends of the shape roll may be compared to theoretically predicted values for a flat product and for product having various out-of-flatness conditions. Preferably the shape roll, is supported at its ends by two pairs of supports an, the measurements at the supports are used in determining roll bending and thence strip unflatness. Other conditions such as off-center strip and asymmetric operation of the …
