Abstract

The apparatus comprises a device producing an opening between a pair of rolls processing a workpiece, and a device for measuring the effective temp of the workpiece. A further device determines the difference between the effective temp of the workpiece and that of a preceding workpiece, and the opening is adjusted according to the latter is response to this difference.
