Claims
- 1. An apparatus for heating a rubber-metal plate composite comprising a plurality of unvulcanized rubber layers and metal plates, each being overlaid alternately, by induction heating, said apparatus comprising:an induction coil for applying a magnetic field to said composite and heating said metal plates due to eddy currents generated by the magnetic field; a power unit for applying an alternating current to said induction coil to generate said magnetic field; and a mold to confine the periphery of said composite, said mold being made of a nonmagnetic or weakly magnetic austenitic stainless steel material with electrical conductivity.
- 2. An apparatus for heating a rubber-metal plate composite comprising a plurality of unvulcanized rubber layers and metal plates, each being overlaid alternately, by induction heating, said apparatus comprising:an induction coil for applying a magnetic field to said composite and heating said metal plates due to eddy currents generated by the magnetic field; a power unit for applying an alternating current to said induction coil to generate said magnetic field; and a mold to confine the periphery of said composite, said mold being made of a nonmagnetic or weakly magnetic material with electrical conductivity, such that 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.
