Abstract

L'INVENTION CONCERNE UN PROCEDE D'ENCAPSULATION D'UN SUPPORT PAR PREPARATION D'UN ASSEMBLAGE COMPRENANT LE SUPPORT, UN ELEMENT D'ENCEINTE ET UN MATERIAU D'ETANCHEIFICATION ET L'ON CHAUFFE L'ASSEMBLAGE POUR MODIFIER LA VISCOSITE DU MATERIAU D'ETANCHEIFICATION. ON OBTIENT DE MEILLEURS RESULTATS EN FAISANT USAGE D'UN ELEMENT CHAUFFANT A L'INTERIEUR DE L'ENCEINTE ET L'ON OBTIENT AINSI UNE DISTRIBUTION PLUS UNIFORME DE LA CHALEUR DANS L'ASSEMBLAGE. L'ELEMENT CHAUFFANT EST DE PREFERENCE DU TYPE PTC, DONT UNE PARTIE AU MOINS EST SEPAREE DE L'ELEMENT D'ENCEINTE PAR LE MATERIAU D'ETANCHEIFICATION. L'INVENTION EST PARTICULIEREMENT PRECIEUSE POUR L'ENCAPSULATION D'EPISSURES POUR DES CABLES TELEPHONIQUES.
