ABSTRACT:
A method for improving the running-out of a metal rolled strip (1), the rolled trailing strip end (1a) 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 (F1, F2, F3. . . Fn) the strip tension (a) is adjusted to stabilize the strip position, provides that shortly before the rolled trailing strip end (1a) exits the developing rolling force differences are measured separately for each roll stand (F1, F2, F3. . . Fn), 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.
