Abstract

PURPOSE:To automatically maintain the prestress strength at constant on purpose to facilitate the operation for changing the set point of the longitudinal position of the roll, by memorizing the prestress strength in the memory, by obtaining the quantity of necessary correction using this memorized value, and by memorizing thus obtained quantity of correction.
