Rolling mill and method for cold or warm flexible one-way or reversible rolling of metal strip

The invention relates to a rolling mill and a method for the flexible rolling of strip material which compensate the mass flow disturbances and Bandzuganderungen occurring during rolling through a powerful driving control of the coil drives with superimposed Leitwertregelung such that the bobbin trains also in the region of the turning points of the belt acceleration in a change of the strip thickness profile, remain constant. In a further embodiment of the rolling mill of this is combined with a S-roll pair as a band memory, which is respectively arranged on and / or downstream of the roll stand, whereby residual error in the mass flow and the strip tension are compensated due to a limited driving dynamics of the coil drives.
