Abstract
While a heated glass sheet moves through a quenching section, the glass sheet is blown with air in the same portions so as to be quenched always in the same portions to provide on the glass surface rapidly cooled portions and uncooled portions. Thereby the residual strains on the glass surface are made different to prevent the generation of pieces or splines when the glass sheet is broken.
