Tandem strip rolling mill has a number of roll stands each of which has a device for measuring the roll separating force due to the presence of the strip between the rolls and an arrangement for adjusting the relative positions of the rolls, and the size of the gap. The screws of the first stand are maintained at their original setting, while adjustments in the screws of succeeding stands made in response to change in the roll-separating force are effected exclusively by signals fed-forward from a preceding stand. The invention also includes an improved appts. for delaying transmission of analog signals for controlled intervals without need for converting the analog signals to digital signals.
