Operating method for a roll stand for rolling a flat rolling stock made of metal, which has a head of the rolling stock, - wherein the roll stand has at least working rollers and support rollers, - wherein the working rollers are mounted in working roller chocks and a bending system that presses the working roller chocks apart acts on the working roller chocks, - wherein the head of the rolling stock reaches the roll stand at an actual entry time, - wherein a base setpoint (FBB*) is supplied to a bending feedback controller and the bending feedback controller determines a resultant setpoint (FB*) taking into account the base setpoint (FBB*), - wherein the bending feedback controller furthermore is supplied an actual value of the bending force, - wherein the bending feedback controller by means of the resultant setpoint (FB*) and the actual value determines a basic manipulated variable for the bending system, so that when the bending system is controlled with the basic manipulated variable, the actual value is approximated as closely as possible to the resultant setpoint (FB*), - wherein the bending feedback controller determines the resultant setpoint (FB*) as from a stabilization time, which is after the entry time, also taking into account an actual rolling force occurring during the rolling of the flat rolling stock, characterized in that during an entry period which begins before the actual entry time and ends after the actual entry time, - the bending feedback controller is supplied with an additional setpoint (FBZ*) in addition to the base setpoint (FBB*), so that the bending feedback controller during the entry period determines the resultant setpoint (FB*) taking into account not only the base setpoint (FBB*) but also the additional setpoint (FBZ*), and as a result the actual value of the bending force is greater than the base setpoint (FBB*) immediately before the actual entry time, and/or - by applying an additional manipulated variable to the basic manipulated variable, a resultant manipulated variable is determined, which is supplied to the bending system and the bending system is thereby controlled in such a manner that the resultant manipulated variable is greater than the basic manipulated variable, and/or - a selection member is supplied the basic manipulated variable and a minimum manipulated variable, and the selection member supplies the maximum of basic manipulated variable and minimum manipulated variable to the bending system. - wherein the roll stand has at least working rollers and support rollers, - wherein the working rollers are mounted in working roller chocks and a bending system that presses the working roller chocks apart acts on the working roller chocks, - wherein the head of the rolling stock reaches the roll stand at an actual entry time, - wherein a base setpoint (FBB*) is supplied to a bending feedback controller and the bending feedback controller determines a resultant setpoint (FB*) taking into account the base setpoint (FBB*), - wherein the bending feedback controller furthermore is supplied an actual value of the bending force, - wherein the bending feedback controller by means of the resultant setpoint (FB*) and the actual value determines a basic manipulated variable for the bending system, so that when the bending system is controlled with the basic manipulated variable, the actual value is approximated as closely as possible to the resultant setpoint (FB*), - wherein the bending feedback controller determines the resultant setpoint (FB*) as from a stabilization time, which is after the entry time, also taking into account an actual rolling force occurring during the rolling of the flat rolling stock, characterized in that during an entry period which begins before the actual entry time and ends after the actual entry time, - the bending feedback controller is supplied with an additional setpoint (FBZ*) in addition to the base setpoint (FBB*), so that the bending feedback controller during the entry period determines the resultant setpoint (FB*) taking into account not only the base setpoint (FBB*) but also the additional setpoint (FBZ*), and as a result the actual value of the bending force is greater than the base setpoint (FBB*) immediately before the actual entry time, and/or - by applying an additional manipulated variable to the basic manipulated variable, a resultant manipulated variable is determined, which is supplied to the bending system and the bending system is thereby controlled in such a manner that the resultant manipulated variable is greater than the basic manipulated variable, and/or - a selection member is supplied the basic manipulated variable and a minimum manipulated variable, and the selection member supplies the maximum of basic manipulated variable and minimum manipulated variable to the bending system.
