Abstract
A process for manufacturing a bent individual glass sheet including a peripheral compression belt, the process including heating a glass sheet to its bending temperature in a furnace, performing an individual bending of the glass sheet, and performing a general cooling of the heated glass sheet, applying to one zone of the glass sheet at least partially inside the peripheral compression belt, which forms a locally cooled zone, after the heating of the glass sheet, a local cooling faster than the general cooling, when the glass sheet is at a temperature of at least 530° C.
Claims22
A process for manufacturing a bent individual glass sheet comprising a peripheral compression belt, the process comprising:
- heating a glass sheet to its bending temperature in a furnace, performing an individual bending of the glass sheet, and performing a general cooling of the heated glass sheet,
- applying to one zone of the glass sheet at least partially inside said peripheral compression belt, which forms a locally cooled zone, after the heating of the glass sheet, a local cooling faster than the general cooling, when the glass sheet is at a temperature of at least 530° C.
