Abstract

L'invention concerne un procédé de fabrication en continu ou en continu/discontinu de panneaux de verre cellulaire, selon lequel le verre est expansé sous la forme d'une barre de verre cellulaire (16) à partir d'au moins une matière première du verre et d'au moins un agent moussant dans un four de moussage puis recuit en continu dans un four de recuit (5) ou en discontinu dans des enceintes de recuit, la barre de verre cellulaire étant amenée à travers le ou les fours sur un système de transport continu pendant le moussage et le recuit, et la barre de verre cellulaire étant découpée à l'état chaud dans le four ou entre deux fours. L'invention porte également sur un dispositif de découpe correspondant et sur une ligne de recuit de verre cellulaire pourvue d'un dispositif de découpe correspondant.
