Abstract
A method and a furnace for bending glass sheets. Glass sheets are heated to a bending temperature by supporting them on a mould (11) and carrying them from one heating station to another. In a bending station (4), the glass sheet is heated for effecting a desired bending partially or entirely through the action of gravity. During a bending operation, the temperature distribution of a glass sheet is subjected to the action of convection blasting. By focusing the blast on the mid-section of a glass sheet it is possible to create a progressively curving pocket.
