Abstract

L’invention concerne un procédé de bombage et un dispositif (10) pour le bombage par gravité d'au moins une feuille de verre comportant au moins un pli support (14) qui, interposé entre ladite au moins une feuille (12) de verre et un support (100, 200) de bombage, est destiné à supporter ladite au moins une feuille (12) de verre au cours du procédé de bombage, caractérisé en ce que ledit pli support (14) est formé par au moins une tôle comportant des découpes (20) qui sont configurées pour lui conférer une capacité de déformation grâce à quoi ladite tôle (14) est apte à prendre au moins une forme de bombage pour façonner ladite au moins une feuille de verre. Figure pour l'abrégé : Figure 2The invention relates to a bending process and a device (10) for the bending by gravity of at least one sheet of glass comprising at least one support ply (14) which, interposed between the said at least one sheet (12) of glass and a bending support (100, 200) is intended to support the said at least one sheet (12) of glass during the bending process, characterized in that the said support ply (14) is formed by at least one sheet comprising cutouts (20) which are configured to give it a capacity for deformation whereby said sheet (14) is able to assume at least one bending shape to shape said at least one sheet of glass.
