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 first and second 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 abutment seating engagement of the orifice housing against the core and casing glass delivery mechanisms. The frame in accordance with the present invention includes a gimbal mounting arrangement mounting the orifice housing to the frame so as to be pivotable about a pair of pivot axes that are orthogonal to each other and to the axis of alignment of the orifices. This gimbal mounting arrangement helps accommodate misalignment between the seating surfaces on the orifice housing and the glass delivery mechanisms, and to reduce glass leakage during operation.
