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.

Manufacture of laminated glazing

A device for holding and capable of conveying a sheet of glass includes a holder intended to support the sheet of glass, in particular in a substantially horizontal position, wherein the device includes a surround including a plurality of support elements which are able to support the sheet of glass locally.

Device for supporting a glass sheet, particularly in a washing facility

A device for manufacturing curved glass, includes a bending station that has a solid concave bending upper mold and a complementary lower countermold, the upper mold being placed above the lower countermold, a conveyor to convey the glass to a final holder placed under the bending upper mold, the final holder being circumscribed, seen from above, by the lower countermold, the final holder forming a surface for receiving the glass, the glass being in an optimal bending position when on this surface, the lower countermold being of the frame type and being able to move vertically in order to pass below or above the surface for receiving the glass, the bending upper mold and the lower countermold being able to move with a relative vertical movement that allows them to be brought together, in order to clamp therebetween the periphery of the glass, and to move apart from each other.

Bending thin glass

A process for assembling a laminated glazing includes placing an overmolded component in the interior of a window cut in a sheet of adhesive; spot bonding the overmolded component and the precut sheet of adhesive to a first glass sheet in the vicinity of the window in order that the sidewalls thereof and of the overmolded component remain contiguous; spot bonding the sheet of adhesive and a second glass sheet; and assembling the laminated glazing by implementing suitable temperatures and pressures in a conventional way.

Method for assembling laminated glazing comprising an overmoulded component

A laminated glazing includes two sheets of glass and a polymer interlayer positioned between them. The first sheet of glass is thicker than the second sheet of glass the thickness of which is less than 1.2 mm. The edge of the second sheet of glass is recessed with respect to the edge of the first sheet of glass over all or part of the periphery of the glazing, thereby making it possible to protect the more fragile second sheet of glass from mechanical knocks against the edge face of the glazing.

Laminated glazing with recessed very thin interior glass

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.

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.

A method for manufacturing dished laminated glazing including two sheets of glass, a separator layer made of polymer material arranged between the sheets of glass, and an electrical conductor, the method including the simultaneous thermal dishing of the sheets of glass in the paired state followed by their cooling and then the assembly of the laminated glazing by bonding of the sheets of glass to the separator layer on either side thereof, the cooling including a controlled cooling of the sheets of glass in the paired state, the controlled cooling including a general controlled cooling and a local controlled cooling of a cutting zone, the local controlled cooling being faster than the general controlled cooling, a cutting of one of the sheets of glass along a cutting line in the cutting zone to form a holed zone, the electrical conductor being placed between the sheets of glass and exiting from the laminated glazing through the holed zone.

Manufacturing laminated glazing provided with an electrical conductor

An automotive vehicle roof that has two longitudinal edges and two transverse edges and that is symmetrical with respect to a median longitudinal plane, the roof consisting of a glazing unit including at least one mineral glass sheet, the sheet including a border of compressive edge stresses and at least two localized zones of compressive stress inside the border, the zones being placed symmetrically relative to the plane of symmetry and each localized zone of compressive stress being less than 30 cm from a longitudinal edge.
