Abstract (en)
Method for thermally toughening glass sheets and glass sheets obtained by this method, in particular to be used as motor vehicle side or rear windows. <??>A method of thermally toughening glass sheets for use as motor vehicle side or rear windows so that the glass sheets produced conform to regulations specifying fracture requirements. <??>The glass sheets are advanced through a quenching station for gas quenching. The glass is subjected to at least one localised gas flow which is pulsed at a repetition frequency related to the speed or advance of the glass sheet through the quenching statement. The method induces in the glass sheet a distribution or regions of more highly toughened glass interspersed with regions of lesser toughened glass.
