  • GLASS MANUFACTURING APPARATUS AND METHODS INCLUDING A THERMAL SHIELD
    Publication number: 20210032149
    Abstract: A glass manufacturing apparatus includes an enclosure including an interior area and a vessel positioned at least partially within the interior area of the enclosure. The vessel includes a trough and a forming wedge including a pair of downwardly inclined surfaces that converge at a root of the vessel. A draw plane extends from the root of the vessel through an opening of the enclosure in a draw direction. The apparatus includes a thermal shield moveable along an adjustment direction extending perpendicular to the draw plane. The thermal shield includes a non-metallic outer shell and a thermal insulating core. Additionally, methods of manufacturing a glass ribbon with the glass manufacturing apparatus are provided.

  • Methods and apparatuses for reducing heat loss from edge directors
    Patent number: 9643874
    Abstract: An apparatus and methods for making a glass ribbon includes a forming wedge with a pair of inclined forming surface portions converging along a downstream direction to form a root. The apparatus further includes an edge director intersecting with at least one of the pair of downwardly inclined forming surface portions, and a replaceable heating cartridge configured to direct heat to the edge director and thermally shield the edge director from heat loss. A replaceable heating cartridge is also provided for directing heat to the edge director and thermally shielding the edge director from heat loss.
