ABSTRACT:
An induction heating coil having fluoroplastic coated polyimide tape wrapped windings for providing a bonded, solid monolithic structure. The induction heating coil includes a cooling fin of predetermined length extending in interleaved relationship between a plurality of consecutive turns of current-carrying coil windings. A plurality of fluoroplastic coated polyimide sheets are fused to the coil body between the coil body and a fluoroplastic face sheet forming the outer wear surface of the induction heater coil, thereby providing a non-stick surface for release of hot melt adhesives.
