Abstract

Procédé et appareil de réglage de la température de feuilles de verre sortant d'un four où elles ont éte chauffées en vue d'un traitement ultérieur. Le procédé et l'appareil qui règlent la température des feuilles de verre se déplaçant en bloc dans un four font varier automatiquement la durée pendant laquelle les feuilles sont chauffées dans le four en fonction de l'écart de leur température moyenne par rapport à une valeur de consigne qui est détectée sur les feuilles chauffées sortant du four. Application au cintrage et à la trempe des vitrages destinés aux automobiles.
