A method for improving the running-out of a metal rolled strip (1), the rolled trailing strip end (la) of which exits out of a respectively last roll stand (2) of a multistand rolling mill (3) at a rolling speed, wherein during rolling between two consecutive roll stands (Fl, F2, F3YFn) the strip tension (a) is adjusted to stabilize the strip position, provides that shortly before the rolled trailing strip end (1 a) exits the developing rolling force differences are measured separately for each roll stand (F1, F2, F3YFn), that from this the pivot value (16) and the pivot direction are derived for forming a corrective value for the adjustment of the rolls (10, 11) and that the adjustment is corrected.

L'invention concerne un procédé destiné à améliorer l'acheminement en sortie d'un feuillard laminé métallique (1), dont l'extrémité (1a) se déplace à vitesse de laminage, d'une cage de laminoir (2) d'un train de laminage multicage (3), considérée comme la dernière, la traction (s) du feuillard étant réglée pendant le laminage, entre deux cages de laminoir successives (F1, F2, F3 Fn) en vue de stabiliser le mouvement du feuillard. L'invention est caractérisée en ce que peu avant que l'extrémité (1a) du feuillard quitte le laminoir, les forces de laminage différentielles produites sont mesurées séparément pour chaque cage de laminoir (F1, F2, F3 Fn) de façon qu'on en déduise la valeur de pivotement (16) et la direction de pivotement en vue d'obtenir une valeur correctrice pour le réglage des cylindres (10, 11), et qu'on corrige le réglage en conséquence.
