Abstract
The refractory tube controlling the flow of glass from a glass feeder bowl is combined with a rotary stirring device used to control surface cord into one unit, herein called a 'Tubex'; thereby eliminating one of the two rotary drive mechanisms and also eliminating alignment and relative rotary speed problems. The stirrers are diamond-shaped platinum-rhodium alloy blades connected to the refractory element, preferably as three, equally-spaced stirrers at a common radius on the rotated Tubex element. A novel rotary support mounting and drive for said element is provided. The Tubex is used in TV panel glass manufacturing.
