Abstract

L'addition concerne un procédé de fabrication de produits en matière thermoplastique réticulée du type décrit au brevet principal, comprenant une mise en forme du produit et une réticulation de ce dernier dans un bain de sel fondu. Suivant l'addition, la réticulation de la matière mise en forme dans un bac 116 est précédée d'un étirage dans un bac 115 comportant des dispositifs profileurs 121a-121d, cet étirage étant effectué à une température voisine de la température de mise en forme de la matière.
