摘要： A flat glass manufacturing facility is provided with a threshold for supporting and delivering a layer of molten glass from a glassmaking furnace to a glass forming chamber containing a pool of glass-supporting molten metal wherein the threshold has an upper glass-supporting surface having one or more transverse grooves, each of which extends from an upstream point near the center of the threshold outwardly to the sides of the threshold and in a direction that is oriented slightly in the direction of the glass delivery over the threshold in order to divert a small portion of molten glass in the lowermost part of the delivered layer of glass to the marginal regions of the delivered layer of glass whereby small bubbles or seeds, products of reaction or other contaminants may be diverted from the main portion of the glass to its marginal portions.
