Abstract

L'invention concerne un procédé de vulcanisation, à l'aide d'ultra-hautes fréquences, d'articles en caoutchouc présentant une pièce métallique. Selon l'invention, on place, au voisinage de ladite pièce métallique, avant l'introduction de l'article dans le tunnel à ultra-hautes fréquences, un isolateur de nature non magnétique apte à arrêter localement la propagation des micro-ondes. Ce procédé s'applique notamment à la vulcanisation de chambres à air munies de leur valve.
