METODO ED APPARECCHIATURA PER LA FABBRICAZIONE DI FIBRE DI VETRO

摘要

A method and apparatus for forming glass fibers employing a generally flat orifice plate having closely spaced orifices is disclosed. A bulk flow of upwardly directed cooling gas which impinges on the orifice plate to eliminate stagnant gas pockets and which surrounds and cools the molten glass cones beneath each orifice is employed to maintain fiber separation and improve fiber formation and properties.
