ABSTRACT:
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.
