Abstract: The invention relates to a method for rolling metal strips, particularly steel strips (S), wherein the metal band runs through a roll gap of at least one rolling stand. The work rolls (A1/1, A1/2) of the rolling stand delimiting the roll gap are displaced in the longitudinal direction of the rotary axis (L1, L2), in case deviations from the shape of a nominal form of the roll gap occur. Said method allows for the rolling of flat products, fulfilling highest expectations in regard to their dimensional accuracy. For this reason, the work rolls (A1/1, A1/2) are displaced following a certain displacement strategy according to the invention, being dependant on achieving certain maximum displacement positions by a steady change of the displacement direction (R-, R+).
