Abstract
A plurality of flat metal items to be rolled () are fed to a plurality of rolling stands () of a rolling installation, one after the other over a feed path (). The items () are rolled by the rolling stands () past which they are fed. In the rolling stands (), the flat item to be rolled () is first rough-rolled in at least one roughing pass with a wedge-type roll gap adjustment (ds) and then finish-rolled in finishing passes. After the finish-rolling of the flat item, a thickness taper (dd) that is present in the respective finish-rolled flat item is recorded by measuring instruments. The thickness taper (dd) is compared with a target taper (dZ). On the basis of a deviation of the thickness taper (dd) from the target taper (dZ) and the wedge-type roll gap adjustment (ds), a new wedge-type roll gap adjustment (ds) is determined for the at least one roughing pass. The wedge-type roll gap adjustment (ds) for the at least one roughing pass for the next flat item to be rolled () is set to correspond to the newly determined value of the wedge-type roll gap adjustment (ds), so that the next flat item to be rolled () is rough-rolled in the at least one roughing pass with the newly determined value of the wedge-type roll gap adjustment (ds).
