Abstract
A heat transfer method in a glass sheet bending furnace and a glass sheet bending furnace for carrying out the method are disclosed. The furnace includes a top array of successive heating sections and a bottom array of successive cooling sections, and glass sheets are placed on bending moulds supported by wagons and are advanced on conveyor tracks through the heating and cooling sections. Heat is transferred from bent, hot glass in a cooling section to unbent, cold glass in a heating section by air which is sucked from the cooling section and blasted into the heating section.
