Abstract
In a roll stand, the working roll inserts are pressed apart by a bending system. A base set-point value (FBB*) is supplied to a bending controller to determine a resultant set-point value (FB*). An actual value (FB) of the bending force is also supplied to the bending controller to determine a base controlled variable (SB) for the bending system so that, when the bending system is actuated with (SB), (FB) is brought as close as possible to (FBB*). From a stabilisation time (t) after an entry time (t), the bending controller determines (FB*), additionally taking an actual rolling force (F) into consideration. During an entry time period before (t) and ending at (t), an additional set-point value (FBZ*) is supplied to the bending controller for determining (FB*). (FB) is thus greater than (FBB*).
