Abstract
A method and an apparatus in a glass sheet bending furnace are disclosed for preventing the deflection of a mould wagon bearing rail as the mould wagon is carried along a conveyor track made up of rollers on which the bearing rails rest, wherein the furnace includes a top array of successive heating sections and a bottom array of successive cooling sections. Deflection of the bearing rails is prevented by blasting cooling air to the top surfaces of the bearing rails in a cooling section of the furnace.
