Abstract

L'invention concerne un appareillage de filtrage. L'appareil de filtrage comporte un corps délimitant un passage 16 d'écoulement d'une matière à l'état fluide ainsi que des orifices d'entrée et de sortie par lesquels une plaque coulissante 11 formant le dispositif de filtrage, peut passer de façon continue ou progressive par pas de toute valeur désirée afin de faire avancer le filtre 12 progressivement au travers du courant de matière fondue. L'orifice de sortie est réalisé sous la forme d'un conduit allongé de section droite supérieure à celle de la plaque coulissante afin de ménager un intervalle dont la largeur permet le mouvement de la plaque coulissante et l'écoulement de la matière au travers de celle-ci, cet orifice est muni d'un joint d'étanchéité constitué par la matière en cours de traitement localement solidifiée. Application à la fabrication d'articles en matières thermoplastiques et thermodurcissables.
