In order to equalize a difference in temperature between the roll ends and the optionally non-coated lateral regions of the metal frame, on one hand, and the coated central region area of the roll, on the other hand, an arrangement for equalizing the difference in temperature is provided by heating the roll ends and the optionally non-coated lateral regions of the metal frame.
