Abstract
In a roll with a roll shell or jacket which is rotatable about a support or beam, the inner side of the rotatable roll shell or jacket is heated by means of an induction coil which is operated at high frequency and provided, for example, at a support element. The heating is effected directly at the press or work nip or in the proximity thereof without substantial loss of energy and without the use of a thermo-sensitive hydraulic medium.
