FIELD: rolling processes and equipment. SUBSTANCE: method comprises use of vertical cogging rolls for setting strip width. At end portions of strip in the result of non-symmetry of transported material, strip width is narrowed. In order to prevent it, positions of cogging rolls are changed at passing end portions of strip according to control characteristic (f) determined with use of parameters (s) preliminarily set on base of predicted behavior of rolling process determined with the aid of neural network. EFFECT: enhanced efficiency of method due to changing characteristic for controlling position of vertical rolls. 24 cl, 10 dwg
