Process for the preparation of glass sheets to be used in laminated glass. The process consists in rendering said glass sheets convex by moving them along a curved path one after another, then cooling them by leading them through blowing chambers and finally, transporting them in lots to the assembly station. The invention also concerns laminated glass, the glass sheets of which have in the central region a core compressive stress of between 1 and 50 MPa.
L'invention concerne un procédé de préparation de feuilles de verre en vue de leur feuilletage. Ce procédé consiste à bom- ber les feuilles de verre en les faisant défiler les unes à la suite des autres selon une trajectoire courbe puis les faire refroidir par passage entre des caissons de soufflage, et à les expédier par lots au poste d'assemblage. L'invention à également pour objet un vitrage feuilleté dont les feuilles de verre présentent dans la zone centrale une contrainte de compression à coeur comprise entre 1 et 50 MPa.
