Title: METHODS AND APPARATUS FOR PRODUCING A GLASS RIBBON
Abstract:
Methods of producing a glass ribbon each includes drawing a glass ribbon along a draw direction and applying a vacuum only to at least one vacuum port located laterally outside of at least one of the opposed edges of the glass ribbon to promote convection cooling of the glass ribbon with a cooling fluid flow generated at least partially by the vacuum being applied to the at least one vacuum port. In further embodiments, draw apparatus includes at least one vacuum port including a passage extending through one of a first end wall and a second end wall of the shroud. Each of the first end wall and the second end wall are located laterally outside a corresponding one of a first lateral end and a second lateral end of a transverse cross section of a draw path.
