Abstract

PURPOSE:To reduce the weight of an induction heating roller unit and prevent the rise in the temperature of the interior of the roller, by providing the cylindrical roller whose inner basic layer is made of a non-electroconductive non- magnetic material and coated with an electroconductive magnetic material and by providing a coil in the roller. CONSTITUTION:A coil 14, which is excited by an AC power source 13, is provided around a core 12 made of a magnetic material and provided on a fixed shaft 11. Roller side plates 15, 16 made of a magnetic material are secured near both the ends of the fixed shaft 11. A cylindrical roller 17 is rotatably supported by bearings 18 on the side plates 15, 16. The roller 17 is composed of an inner cylindrical layer 17a made of a non-electroconductive non-magnetic material as a base and an outer layer 17b made of an electroconductive magnetic material and extending on the outside surface of the inner layer. Since various kinds of heating are caused only in the outer layer 17b, the temperature inside the roller 17 is kept from rising.
