    • 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.
    • 当在辊架上轧制板材或条带时,其使用工作辊,其被支撑在备用辊上或具有支撑辊的中间辊上,由此辊间隙的设定通过轴向移位设置有弯曲轮廓的辊对来实现,差异 在产品范围较宽的情况下,由于在产品平面度上以所谓的四分之一波浪的形式表现的边缘区域或四分之一区域中的过度扩展,所以要求的分布发生。 为了通过使用简单的机构来解决这个问题,并且改进了在机车车辆的整个宽度上制造具有预定厚度轮廓的绝对平面条带的设定机构和策略,本发明提供了用于形成辊隙组合轮廓 (10,11),对于两个选定的位移位置,一个辊对的辊的轮廓成形为使得它们在辊隙中产生轮廓(20,21),轮廓(20,21)关于 辊的中心具有在辊的中心最大的轮廓,该轮廓可以通过移动辊而改变,而至少一个第二辊对的辊的轮廓在辊间隙中产生轮廓(22, 23),其对于辊的中心是对称的,并且在辊的中心之外具有两个相同的最大值,该最大值可以通过移动辊而改变。
