Abstract (en)
Yankee (1) for paper production consisting of a body comprising a metal mantle (2) with circular cross-section and two side heads (3) on which are formed or mounted two respective coaxial pins (4) arranged along a rotation axis (x-x) of the Yankee, said body being configured to rotate with a predetermined angular speed around said rotation axis (x-x). Inside said body is arranged a fixed electromagnetic induction heating system comprising one or more inductors (H; HN) interacting electromagnetically with the mantle (2) to produce induced electric currents in the same mantle, said one or more inductors (H; HN) being arranged in proximity of the radially innermost surface of the mantle (2).
