The invention relates to a mill train (1) for milling a strip-type product to be milled (10). Said mill train comprises a number of roll stands (2) which are successively arranged in a milling direction (x) and which can be respectively pivoted about a rotational axis (18) which is essentially perpendicular to the milling direction (x). The aim of the invention is to maintain a belt run which favors a pre-determined milling result, in an especially simple and reliable manner. According to the invention, a control value (S) is pre-determined for the pivoting angle of a roll stand, or of each roll stand (2), according to the determined contour of the strip end (30) of a product (10) which has already been milled. According to the invention, additional control elements can also be used.
Method of operating a mill train (1) for rolling strip-like rolling stock (10) with an edger and a number of roll stands (2) arranged one behind the other in a rolling direction (x), comprising using a number of adjusting units (20) to affect a contour trailing end (30) of the strip, presetting a control value (S) for an adjusting unit or for each adjusting unit (20) assigned to a roll stand (2) or an edger as a function of the contour determined for the strip trailing end (30) of a product (10) that has already been rolled, readjusting the control value or each control value (S) in such a way that the contour of the strip trailing end (30) assumes a maximum (36) in the width direction (y) of the strip at a position that can be preset as a set point, further comprising presetting a set point for the position of the maximum (36) in the width direction (y) and/or for the thickness taper of the strip trailing end (30) as a function of the position of the given roll stand (2) in the mill train (1).
