A glass tempering furnace and a method for heating a glass sheet. The glass sheet is heated in the glass tempering furnace by blowing heating air on the top surface of the glass sheet, and the blowing distance of the heating air from the top surface of the glass sheet is adjusted.

Method for heating glass sheet, and glass tempering furnace

The invention relates to a method for heating glass sheets, and a glass tempering furnace. The glass sheets are heated by feeding them through a tempering furnace whereby the glass sheets are heated from above and below in the tempering furnace. The glass sheets are heated with blowing channels arranged substantially transverse in relation to the direction of travel of the glass sheets and with heating resistor rows arranged substantially transverse in relation to the direction of travel of the glass sheets. A heating resistor row has at least three separately controllable parts, and the temperature profile of the glass sheet is adjusted in the transverse direction by separately adjusting the different parts of the resistor row.
