Abstract

Rolling mill has the speed of the strip regulated by passing it between drive units at intervals. These have stands with freely rotating wheels which support a two-high roller unit, lying across it. The upper roller is driven by a motor at one end. The other roller, at the bottom, has a recorder or pick-up at the end opposite to the motor. The output signals from this pick-up are passed into an integrating unit where the actual rotational speed is compared with the theoretical value required. The result is fed into the motor as a corrective value.
