Abstract

L'appareil de vulcanisation décrit est constitué de deux plateaux chauffants avec des vides semi-cylindriques qui encerclent et reçoivent le câble. Chaque plateau est équipé d'un élément chauffant, et au moins un actionneur linéaire peut être présent pour régler les plateaux entre des configurations ouverte et fermée. La taille des vides semi-cylindriques peut être modifiée par l'ajout de différents ensembles de manchons à bride, ce qui permet un réglage sur la base de la taille du câble en cours de traitement.
