GLASS FORMING APPARATUSES HAVING INJECTION AND EXTRACTION PORTS AND METHODS OF COOLING GLASS USING THE SAME

Abstract:

Glass forming apparatuses which decrease dimensional variations in glass ribbons are disclosed. In embodiments, a glass forming apparatus may include a forming body defining a draw plane that extends in a draw direction. An enclosure may extend in the draw direction below the forming body. The enclosure may include a compartment positioned below the forming body in the draw direction. The compartment may include a cooled wall positioned adjacent to the draw plane, a fluid conduit positioned within the compartment and adjacent to the cooled wall, an extraction port extending through the cooled wall and positioned in the draw direction from the fluid conduit, and an injection port extending through the cooled wall and positioned in the draw direction from the fluid conduit.
