Abstract
The invention relates to a method and a furnace for bending glass sheets. Glass sheets supported on ring molds are heated to a bending temperature and are carried from one heating station to another. In a heating and bending station, 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 radiation heat is adjusted. In the heating stations, the glass sheet is subjected to the action of convection blasting.
