  • Method and apparatus for glass ribbon thermal control
    Patent number: 11512015
    Abstract: A method and apparatus for manufacturing a glass article includes flowing a glass ribbon through a housing having first and second side walls. The first and second side walls extend between the glass ribbon and a cooling mechanism and at least one of the side walls has at least one closeable opening, such that a greater amount of heat is transferred from the glass ribbon when the closeable opening is open than when the closeable opening is closed.
    Type: Grant

  • Method of producing glass ribbon
    Patent number: 10604436
    Abstract: Methods for producing a glass ribbon include drawing a quantity of molten material from a forming vessel into a glass ribbon with the forming vessel positioned within a first portion of a housing located within an upper chamber. The methods further include drawing the glass ribbon along a draw path passing through a second portion of the housing at least partially located within a lower chamber. The methods further include venting gas from an interior of housing through a wall of the second portion of the housing. In one example, the method further includes maintaining a pressure difference between the lower chamber and the upper chamber. In another example, the method includes maintaining a pressure difference between the interior of the housing and the upper chamber.
