Abstract

Cette buse comporte un élément chauffant électrique avec un canal interne 24 à travers lequel s'écoule la matiere plastique fondue, une enveloppe 10, 11 et des orifices de sortie 5 dans la région de son extrémité avant, la section de cet élément chauffant diminuant en direction de la pointe de la buse. Selon l'invention, une résistance chauffante 9, liée à l'enveloppe, est montée avec une disposition centrale, la section de cette résistance diminuant vers son extrémité avant, et il est prévu, entre la partie de section décroissante et la partie de section courante de ladite résistance, une autre partie 16 présentant une surface importante, et possédant une section égale ou supérieure à la section courante de la résistance. Cette partie 16 est située au voisinage des orifices de sortie 5, délimités par des languettes qui prolongent la partie avant 10 de l'enveloppe.
