Summary: | The invention relates to a solid mould (3) for bending by pressing glass sheets (1) taken to a deformation temperature, the mould (3) comprising a bending surface (43, 52), the mould (3) comprising an electric heating circuit (21) distributed in the mould (3) and a cooling circuit (20) through which a coolant fluid flows distributed in the mould (3), the heating circuit being positioned between the bending the surface (43, 52) and the cooling circuit (20). The mould (3) according to the invention can be easily adjusted in order to have a highly uniform temperature of the bending surface (43, 52). The mould (3) is particularly suitable for bending glass having thickness of at most 2.1 mm.
L'invention concerne une forme (3) pleine de bombage par pressage de feuilles de verre (1) portées à une température de déformation, ladite forme (3) comprenant une surface de bombage (43, 52), ladite forme (3) comprenant un circuit de chauffage électrique (21) réparti dans la forme (3) et un circuit de refroidissement (20) parcouru par un fluide de refroidissement réparti dans la forme (3), le circuit de chauffage étant positionné entre la surface de bombage (43, 52) et le circuit de refroidissement (20). La forme (3) selon l'invention se laisse aisément réguler pour avoir une température de surface de bombage (43, 52) bien homogène. La forme (3) est particulièrement adaptée au bombage de verre d'épaisseur au plus égale à 2,1 mm. |
