Device and method for rolling metal strip

The invention relates to a device (10) and a method for rolling a metal strip. In this case, the distance of the upper support roller (18)/lower support roller (20) at at least one point thereof to a predetermined upper reference point (P1)/lower reference point (P2) is measured by an upper sensor (24)/lower sensor (25), and the measured values of the sensors are sent to a control device. The strain of the roll stand (12) is calculated by means of a mathematical module, taking into account the generated rolling force. According to the invention, the absolute dimension of the nip and the resulting rolled stock thickness are determined by means of a control device on the basis of the measured positions of the support rolls (18, 20) and the calculated strain of the roll stand (12), the absolute value of the nip being compared with a target value of the nip by means of the control device and then the at least one support roll (18, 20) being adjusted vertically on the basis thereof, in this way, the roller gap is
