ABSTRACT:
Apparatus for forming a cased glass stream that includes at least one pair of aligned orifices coupled to sources of core and casing glass such that glass flows by gravity from the glass sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing mounted on a frame for movement into seating engagement of the orifice housing against the core and casing glass delivery mechanisms. A fluid manifold is mounted on the orifice housing, with an inlet for connection to a source of cooling fluid such as air. A plurality of outlets on the manifold are directed toward the area of seating engagement between the orifice ring housing and the core and casing glass delivery mechanisms for cooling the seating area and thereby reducing leakage of glass between the housing and the glass delivery mechanisms. Inasmuch as the cooling air manifold is mounted on and carried by the orifice housing, the manifold outlets are automatically directed toward the seating area upon seating of the orifice housing against the glass delivery mechanisms, and do not require separate replacement or adjustment.
