Abstract
An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.
