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.

A method for continuously measuring the flatness of a moving hot metal strip, the method comprising projecting a shadow in the form of a line pattern onto said moving hot metal strip, and detecting said line pattern on said moving hot metal strip with a camera.
A method for continuously measuring the flatness of an end face of a coil when coiling a metal strip, the method comprising the steps of projecting a shadow in the form of a line pattern onto said end face, and detecting said line pattern on said end face with a camera.
