<p>The invention relates to a heat treating method for glass sheets, in which heating and cooling jets (6) directed at the surfaces (2) of the glass sheet (1) remove electrons (7 and 9), part (9) of which are earthed by means of the surrounding devices (10), the surfaces (2) becoming positively (8) charged. In accordance with the invention, negative (11) charges are produced in place of the electrons (9) that are lost, which charges are transported along with the air jets (6) to the surfaces (2) of the glass, the positive charge (8) of said surfaces being cancelled. The invention also relates to an apparatus for carrying out the heat treatment.</p> |
