Abstract

The invention relates to rolled material comprising a front and an end. The rolled material is rolled in a roll gap of a roll stand to a first desired measurement, beginning at the front of the rolled material. When the rolled material is being rolled in the roll stand, it is continuously determined by a control computer, which locates the position of the rolled material which is currently in the roll gap. When the position of the rolled material, which is directly in the roll gap, corresponds to a predetermined first modification position of the rolled material, which is arranged between the front of the rolled material and the end of the rolled material, the roller of the rolled material ends at a first desired measurement such that a first step is introduced into the rolled material on the first modification point.
