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.

Abstract: A device and a process for manufacturing a bent individual glass sheet including a peripheral compression belt, wherein the process includes the heating thereof to its bending temperature in a furnace, the individual bending thereof, and the general cooling thereof. One zone of the sheet at least partially inside the peripheral compression belt, referred to as locally cooled zone, undergoes, after the heating of the sheet, a local cooling faster than the general cooling, when the sheet is at a temperature of at least 530° C. The cutting of the sheet on the locally cooled zone creates edges having edge compressive stresses.
