ABSTRACT:
The invention concerns a heated roll and a method for heating of a roll, in particular of a press roll or calender roll in a paper or board machine. The roll has a hollow, tubular roll mantle. According to the invention, the roll is heated with electric current by means of electrical resistors fitted inside the body material of roll mantle. The heating is preferably applied to the roll substantially at the proximity of the face of the roll mantle, and the electric current may be supplied to the electrical resistors from the ends of the roll through glide rings.
