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.

Abstract: A bending station for a bending device, includes two bending molds, a pressing frame arranged to adapt to the glass sheet and to press it against an upper mold, the upper mold including a molding face, the area of which, defined by projecting the contour of the upper mold onto a horizontal plane, is greater than the area defined by projecting the outer contour of the pressing frame and the glass sheet onto the same horizontal plane, the pressing frame including a pressing ring having a continuous surface, the upper mold including a flexible sheet associated with an upper series of translational elements, wherein the upper mold is able to deform under the effect of the translational elements of the upper series in order to obtain a deflection value varying by at least 5 mm.

Abstract: 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.

Abstract: 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.

Abstract: A shaping tool includes a membrane made of a polymer material, the membrane having a shaping surface, and a thermalization system inserted into the membrane. Moreover, a method for constructing a membrane of a shaping tool includes providing a mold with a shape of the membrane to be made and a polymer material that constitutes the membrane; pouring the material into the mold; cross-linking the material; providing a thermalization device and providing a device for increasing thermal conductivity.

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.
