Abstract
A method of rolling strip, particularly metal strip, for example, steel strip, in a rolling train with several roll stands arranged one behind the other, wherein the strip enters each of the roll stands with a desired entry thickness and each of the roll stands is provided with a desired thickness value of the strip, and wherein the strip is to leave the respective roll stand with a thickness which corresponds to this desired thickness value; when rolling a transition portion of the strip, i.e., a portion of the strip where the thickness of the strip changes, the desired thickness value of one of the roll stands is changed from an initial desired value to a final desired value; when rolling the transition portion of the strip in any roll stand arranged subsequent to the one roll stand, the desired thickness values of these roll stands are also changed from initial desired values to final desired values. The changes of the desired thickness values in any roll stands following the one selected roll stand is carried out in such a way that for each of these roll stands the quotient of the instantaneous desired thickness value of this stand and the instantaneous desired entry thickness of this stand is a constant.
