摘要： 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.

摘要： A cooling frame for a bent glass sheet, includes a support track for the sheet and a removable bearing piece that is able, in a bearing position and during cooling of the sheet by air blowing, to bear on the top face of the sheet and at the periphery thereof. The bent sheet cooled on the cooling frame maintains contact with the frame during the cooling operation and its shape complies better with that which is desired.
