<p>1. Industrial machine heated by induction, comprising a metallic heating cylinder (150), induction-type heating means (50) incorporated to the inside of the heating cylinder (150) and means (126, 127) for driving the heating cylinder (150) in rotation, characterized in that the heating means (50) incorporated to the heating cylinder (150) comprises a series (1 to 9) of non-joined conducting bars (51), parallel to the generatrices of the heating cylionder and egularly distributed inside the heating cylinder (150) while defining a cylindrical zone (152) of diameter smaller than the diameter of the heating cylinder, each conducting bar (51) being embedded in an material (52) which is electrically insultating and good conductor of heat, the embedding material (52) being itself covered with a metallic envelope (53) in thermal contact with the internal face (153) of the external metallic wall of the heating cylinder (150) and the different conducting bars (1 to 9) being intercinnected and connected to an A.C supply source.</p> |
