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 process for manufacturing laminated glazing comprising at least two glass substrates and at least one interlayer made of a polymer material arranged between the substrates, the process comprising in the following order:
A laminated glazing comprising at least two glass substrates and at least one interlayer made of a polymer material arranged between the at least two substrates, and at least one notch or orifice cut in its thickness, wherein cut contours of the two glass substrates in the notch or orifice have a perfect superposition, and wherein compressive edge stresses of said contours are greater than 4 MPa.
An opening sunroof of a vehicle made of laminated glazing comprising at least two portions that are moveable closer together or moveable apart, said portions being perfectly coincident at the edges of the portions intended to be moved closer together and at curvatures of all of the glazing.
A laminated glazing comprising at least two glass substrates, comprising a border of compressive edge stresses and locally comprising in each of the at least two glass substrates and in a superposed manner in all the at least two glass substrates a local zone of compressive stresses free of orifices and different from said border, enabling a cutting of said glazing along a line within said local zone in order to form, after cutting, edges having compressive edge stresses of greater than 4 MPa.
