摘要: When rolling sheets or strips in roll stands using working rolls, which are supported on back-up rolls or on intermediate rolls having back-up rolls, whereby the setting of the roll gap is effected by axially displacing roll pairs provided with curved contours, differences from the required profile occur in the instance of larger widths of a product range due to excessive extensions in the edge areas or in the quarter areas that are manifested in the form of so-called quarter waves in the flatness of the product. In order to rectify this problem by using a simple mechanism and to improve the setting mechanism and the strategy for creating absolutely planar strips with a predetermined thickness profile over the entire width of the rolling stock, the invention provides that for forming the roll gap set profiles (10, 11) for two selected displacing positions, the contours of the rolls of one roll pair are shaped in such a manner that they produce, in the roll gap, a profile (20, 21), which is symmetric with regard to the center of the roll and which has a profile maximum in the center of the roll that can be altered by displacing the rolls, whereas the contours of the rolls of at least one second roll pair produce, in the roll gap, a profile (22, 23), which is symmetric with regard to the center of the roll and which has two identical maxima outside of the center of the roll that can be altered by displacing the rolls.
