Abstract
A method for heating LowE glass panels in a tempering furnace ( ) provided with rollers. LowE glass panels are carried on a conveyor constituted by rollers ( ) into the tempering furnace and then the discussed glass panels are set in an oscillating motion within the tempering furnace for the duration of a heating cycle. This is followed by delivering the discussed glass panels into a tempering station ( ). In the tempering furnace, the glass panels are heated by means of top and bottom radiation heating elements ( ), as well as by top and bottom convection heating elements ( ). In the early stage of a heating cycle the top glass surface is subjected to convection heating more powerful than that applied to the bottom surface and in the final stage of a heating cycle the bottom glass surface is subjected to convection heating more powerful than that applied to the top surface.
