Abstract (en)
[origin: EP0752285A2] Rolling strips (B) of non-uniform thickness, and/or length distribution over their width, involves using at least one pivotable control roll (5, 9) on the entry and/or exit side (E, A) of a roll stand (W). The tensile stress is determined over the strip width, by measuring device(s) (7, 11) located on the same side as the control roll. Dependent on the tensile stress distribution obtained, the control roll (5, 9) is adjusted until this distribution corresponds to a target value. Also claimed is an appts. for implementation of the proposed method.
