  • Patent number: 11964896
    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.

  • Patent number: 10724292
    Abstract: A laminated includes two bent glass substrates, a polymer interlayer between the glass substrates, and a notch or orifice cut in an entire thickness of the glazing. The glazing includes a border of compressive edge stresses obtained by general controlled cooling of the substrates in a paired state so that compressive stresses are generated at the border, and a local compression zone, different from the border, and obtained by local controlled cooling of a local area of a main surface of the glazing so that compressive stresses are generated in theid local compression zone. The notch or orifice is located in the local compression zone and made in the substrates in a paired state after forming the local compression zone so that cut contours of the substrates in the notch or orifice have a perfect superposition. The compressive edge stresses of the cut contours are greater than 4 MPa.
