Abstract

Procédé de fabrication d'un coude de tuyau en matière thermoplastique, par chauffage d'un tronçon de tuyau droit jusqu'au voisinage de la température optimale de déformation à chaud de la matière plastique, introduction d'un noyau de soutien à l'intérieur du tuyau et cintrage du tronçon de tuyau autour d'un gabarit Après le chauffage, on introduit dans le tronçon de tuyau chaud un noyau formé de lamelles déplaçables entre elles et on cintre le tronçon de tuyau, avec interposition d'une fourrure élastique extensible, autour d'un disque circulaire dont le rayon correspond au rayon de courbure intérieur du coude diminué de l'épaisseur de la fourrure, laquelle détermine en se dilatant une expansion de la face interne du coude de tuyau Dispositif pour la mise en oeuvre de ce procédé.
