Abstract

Apparatus for producing a glass ribbon includes a convection cooling device including at least one vacuum source configured to promote convection cooling of the glass ribbon by forcing a cooling fluid to flow along the glass ribbon. In further examples, methods of producing glass ribbon include the step of creating a vacuum to promote convection cooling of the glass ribbon by forcing a cooling fluid to flow along the glass ribbon.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application Serial No. 61 / 829,566, filed May 31, 2013, which application is based upon and is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to apparatus and methods for producing glass ribbon, and more particularly to apparatus and methods for producing glass ribbon with at least one vacuum source configured to flow to facilitate convective cooling of the glass ribbon. Background technique [0004] Drawing apparatus is known for drawing glass ribbons. The glass ribbon can subsequently be divided to produce multiple glass sheets that can be used in a variety of applications. It is known to draw glass ribbons in a viscous state, eventually cooling to an elastic state in which the final features are permanently solidified into the glass sheet. [0005] Existing known methods cool glass sheets by radiative heat tr...
