Abstract: A cold-rolling train has a plurality of rolling stands and a strip feeding device to which an initial setpoint speed is sent to feed the cold strip to the first stand at an initial actual speed corresponding to the initial setpoint speed. A first setpoint speed is sent to the first stand so that associated rolls rotate. Between the first and next passed-through rolling stand is a thickness detection device detecting a first actual thickness. A base output signal is determined using the first actual and setpoint thicknesses and is used to adjust the first setpoint speed, but not the initial setpoint speed, conforming the first actual to the first setpoint thickness. Between the feeding device and the first rolling stand is an initial thickness detection device detecting an initial actual thickness. The initial setpoint speed is adjusted by a initial feed-forward controller to adjusted a setpoint product mass flow.
