When a metal band (5) is rolled in a blooming train (1) and in a finishing train (2), the rolling process is adjusted in the blooming train (1) in a manner known per se depending on a prediction value (ypre) of the change in width of the metal band (5) in the finishing train (2) so that the metal band has a predetermined final width (corresponding to the set width) when it leaves the finishing train. In order to allow the change in width to be reliably predicted in spite of the lack of accurate information on the relation between the change in width and influencing variables that act on the process, this relation is simulated in a neuronal network (13) the parameters of which are adaptively modified after each run of the metal band (5) through the finishing train (2) depending on influencing variables (xpost) measured or calculated during the run and the real change in width (yreal) measured.
