Christoph Link: Roll with induction heating arrangement. Sulzer Escher Wyss, Sandler Greenblum & Bernstein, December 24, 1991: US05074019 (51 worldwide citation)

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 ...
