Abstract: The invention relates to a gravity bending oven for glass panes, provided with several heating groups (5) (16) which are arranged in a cistern-shaped oven lower part (1) and a cover-shaped oven upper-part (2), and heat insulation (8) arranged on the inside of the oven walls (7). According to the invention, a plurality of channels (9) are arranged in the heat insulation, said channels being cross-flown by a heat transfer medium and are used to guide heat away from the heat insulation. The invention also relates to a gravity bending method for glass panes, which can be carried out, preferably, using said type of oven.

Abstract: The invention relates to a sheet glass oven, in particular for tempering glass panes including a lower oven part provided with stove rollers for transporting the temperable glass panes, where the axes of rotation of the oven rollers are arranged substantially in a perpendicular position to the direction of a glass pane extension. The oven also includes a top oven part having a central section and a lid. The oven is also provided with lower heating groups and top heating groups, where the heating groups extend under the oven rollers and the top heating groups extend thereabove and are formed by electric heat resistances.
