Abstract
A process for controlling the flatness of a metal sheet subjected to a cold-rolling operation by the measurement of the tensions in different regions of the width of the sheet. There are at least three regions. The process comprises calculating the sum of the tensions measured in the respective regions, calculating from the result obtained the theoretical tension in each region corresponding to a tension uniformly distributed along the width of the sheet, comparing said theoretical tension with the tension effectively measured in the corresponding region and exerting, if required, the required correcting actions as a function of the results of said comparison.
