  • Patent number: 11702883
    Abstract: A process for manufacturing a bent laminated glazing, includes manufacturing a first bent laminated glazing including at least two glass substrates locally comprising, in each of the at least two glass substrates and facing each other in all the at least two glass substrates, a zone including compressive stresses, and cutting the first bent laminated glazing through its entire thickness along a line included in the zone in order to form local cut edges and, after cutting, a second bent laminated glazing with the local cut edges having compressive edge stresses.
    Type: Grant

  • 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.

  • Patent number: 9670714
    Abstract: A method for manufacturing a laminated glass panel, which includes at least two glass substrates and at least one intermediate layer made of a polymeric material arranged between the substrates, the method including in the following order: the bending of the substrates; the controlled cooling of the substrates; and the formation of a laminated assembly that includes the substrates and the intermediate layer; the cutting of the laminated assembly straight through the entire thickness thereof along a line on one of the main surfaces thereof, the controlled cooling including general controlled cooling and local controlled cooling of an area that includes the cutting line, the local controlled cooling being faster than the general controlled cooling.

  • Patent number: 9452947
    Abstract: A furnace for heating an object in a space, including a refractory ceramic wall, a heat source, at least one metal plate coated with an adherent layer of ceramic material on one of its principal faces, the coated plate being placed between the wall and the source, the adherent layer being situated facing the source. The coated metal plate acts as a thermal barrier and improves heating efficiency of the heat source. The furnace may for example serve to bend by gravity glass sheets placed on a bending frame.
