ABSTRACT:
Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by a chamber that communicates with the second orifice through a gap between the first and second orifices. A spout delivers casing glass from a second source through a tube to the chamber in such a way that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. Rate of glass flow through the second or casing glass source is measured and compared with one or more preset limits. Rate of casing glass flow from the second source to the chamber surrounding the orifices is adjusted when rate of flow through the second source departs from the preset limit. In this way, a desired ratio of casing glass to core glass is automatically maintained.
