Method for controlling the shape of rolling stock in a roll train comprising a plurality of roll stands. The values for the change in thickness reduction for the roll stands, the said values being selected for the purpose of shape correction and increasing in the sequence of the roll stands, are determined as a function of the output signal of a sensor for the shape of the end product arranged downstream of the outlet of the last roll stand. The correction stages are determined in such a way that the deviation in shape is limited to a permissible range and that the shape correction in each roll stand is carried out at precisely the time of arrival of that part of the rolling stock on which a shape correction has been carried out on the preceding roll stand, taking into account the speed of passage of the rolling stock and the spacing between the roll stands, while the thickness of the final rolled product is kept to a fixed value. |
