Abstract

Four pour la cuisson de matériaux céramiques, notamment de carreaux de matériau céramique. Il comporte un certain nombre de canaux superposés 11, 12, chaque canal étant délimité par des parois latérales 16 isolées thermiquement, par un plafond 20 et par un fond 19, des moyens 22, 27 pour chauffer ces canaux et un certain nombre de rouleaux 17, pour supporter et faire avancer les matériaux céramiques 18 à travers le four, disposés transversalement dans chaque canal et espacés uniformément l'un de l'autre, longitudinalement, au moins sur une partie importante de la longueur du four, ces rouleaux étant plus rapprochés du plafond que du fond des canaux correspondants. Application : cuisson de matériaux céramiques.
