Abstract

L’invention concerne un dispositif et un procédé de bombage et de refroidissement d’une feuille de verre ou d’un empilement de feuilles de verre, dit le verre, comprenant le bombage par gravité du verre chauffé jusqu’à une température maximale de bombage sur un support gravitaire au cours duquel le verre repose sur le support gravitaire dans la zone périphérique de sa face inférieure, ladite zone périphérique étant constituée des 50 mm à partir du bord de la face inférieure, puis, ledit procédé comprenant le refroidissement du verre menant à son figeage, le séquençage suivant étant effectué au moins une fois pendant ledit refroidissement menant à son figeage, la prise en charge du verre par un outil de séparation le séparant du support gravitaire et laissant sa face inférieure libre de tout contact dans sa zone périphérique, puis le supportage à nouveau du verre sur le support gravitaire dans la zone périphérique de sa face inférieure.
