Abstract
The invention relates to a method and furnace apparatus for bending and tempering glass sheets. A glass sheet is supported on the same outline mold throughout the entire handling process. A bending furnace (10) is designed to be sufficiently long in the traveling direction for carrying a partially bent glass sheet towards a tempering section (16) in such a manner that the glass sheet reaches its final shape during the passage occurring within the bending furnace (10). For this purpose, the glass sheet is heated in the bending furnace (10) with such a high effect that it reaches its tempering temperature before reaching its final shape. The movements and heating of glass sheets are controlled individually on the basis of the thickness and measured temperature of each glass sheet.
