<p>Method to vulcanise rubber articles or profiles (14, 114) obtained by means of compression inside a mould (13) or by means of injection or extrusion from an extruder (18) associated with a transport or supporting plane (20), the method providing that the article or profile (14, 114) to be vulcanised is subjected to the action of a variable electric field with a frequency of at least more than 1 MHz and suitable to take the temperature of the article or profile (14, 114) to a value at least equal to 140 DEG while maintaining the walls of the mould (13) or the surface of the transport or supporting plane (20) substantially at ambient temperature. Device for the vulcanisation of rubber articles or profiles (14, 114) obtained by means of compression inside a mould (13) or by means of injection or extrusion from an extruder (18), the device comprising at least a radio-frequency generator (16), associated with at least a pair of electrodes, suitable to generate a variable radio-frequency electric field acting on the article or profile (14, 114), the electric field having a frequency of at least more than 1 MHz and such as to take to at least 140 DEG C the temperature of the rubber article or profile (14, 114) arranged inside the mould (13) or travelling on a transport or supporting plane (20). <IMAGE></p> |
