Claim 12:
13. The method according to claim 11,
wherein when using the device for the axial displacement of the S-shaped profiled work roll, an equivalent roll gap profile adjustment range ΔCWS for the sum of the profile and flatness control elements of the rolling stand is generated at least at the first rolling stand with active profile and flatness control elements to:

ΔCWS>KB′·Bmax2 

with
KB=0.16 mm/m2 or KB=0.20 mm/m2 as factor,
ΔCWS in mm referring to a change of the roll gap profile when changing the setting position of the profile control element or control elements of the stand between the min./max. adjustment range (calculated values without taking into account the interaction with the strip at the strip profile reference point, for example X=40 mm or X=25 mm offset inwards from the strip edge), and
Bmax in m referring to a maximum target width of the strip.
