Abstract
An alternating current with a frequency comprised between 1 MHz and 10 GHz is generated in a portion of the conductor element (38) limited by two short circuits (12, 13), thereby causing a heating by Joule effect of said conductor element portion. To generate said current, the electromagnetic energy emitted by the microwave or high-frequency generator (1) emitting at the selected frequency is electrically or magnetically coupled by means of an applicator (2, 7) to the conductor element portion acting as antenna tuned on the emission frequency of the generator (1). Application, among other things, to the homogeneous coating of a conductor element, for example based on carbon fibres, carrying a continuous element, for example based on carbon fibres, carrying a continuous or discontinuous coating of thermoplastic material susceptible of heating and melting by thermal conduction.
