Abstract
The invention concerns a method for cambering glass sheets that are part of the composition of a laminate, comprising raising the temperature until the sheets soften, and shaping the sheets; in said method, after said shaping, the sheets are rapidly cooled to a temperature no greater than that of the glass-transition range, said cooling being carried out in an atmosphere having a controlled temperature in a forced convection treating the two faces of the sheets exposed to said atmosphere and providing a homogeneous temperature over the entire surface area of said sheets, apart from, possibly, the edges of said sheets if said edges are in contact with the support during said cooling.
