Abstract: A process and apparatus for producing glass foil is disclosed in which a thin glass foil is produced by conveying a glass melt from a rotatable crucible of a smelting furnace through an annular distribution reservoir and a distributing disk having flow-through slots. Jets of glass emerge from the flow-through slots and are combined at a funnel-shaped wall into a hollow, cylindrical glass mass. Due to its weight and to heating by pressurized, gas-heated heating and cooling zones, the cylindrical glass mass flows downward, and is stretched until it reaches a pre-determined wall thickness by auxiliary conveyor belts. The hollow cylinder of glass is then split on one side by a separating device, flattened, conveyed to a bath of liquids, and then drawn-off at full width in the form of a glass foil by a draw-off guide roller. After the glass foil is drawn-off, the auxiliary conveyor belts are moved laterally so that they are no longer in physical contact with the glass cylinder.
