Abstract
An apparatus for heating a rubber-metal plate composite formed of a plurality of unvulcanized rubber layers and metal plates, each being overlaid alternately, by induction heating, includes an induction coil for applying a magnetic field to the composite and heating the metal plates due to eddy currents generated by the magnetic field, a power unit for applying an alternating current to the induction coil to generate the magnetic field, and a mold to confine the periphery of the composite. The mold is made of a nonmagnetic or weakly magnetic material with electrical conductivity, such as austenitic stainless steel. The mold generates enough heat to function as the heating unit by generating eddy currents in the conductive mold while magnetic flux permeates the mold substantially without loss and reaches the composite therein.
