Abstract

The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.
