Zusammenfassung:The invention concerns a roll, in particular a roll for a soft calender or supercalender, which roll comprises a metal frame (12), ends (13), and shafts (14), the frame (12) of said roll (10) being coated with a polymer coating (15). In view of equalizing the difference in temperature between the roll (10) ends (13) and the non-coated lateral areas of the metal frame (12), on one hand, and the coated (15) middle area of the roll (10), on the other hand, an arrangement (16;20) for equalizing the difference in temperature has been fitted in connection with the roll (10) ends (13) and with the non-coated lateral areas of the metal frame (12).
