Abstract

PURPOSE: To carry out the highly accurate control of the titled sheet width, by estimating the required tension necessary to control the weighted mean value of the deviation is the sheet width of the the rolled material existing between the stands, on purpose to use this mean value for the aimed tension of the tension controller.
