METHOD AND APPARATUS FOR PROCESSING GLASS

A method of forming glass fibers includes maintaining heat-softened glass at a perforated planar area of a thin metallic plate, establishing pressure of the heat-softened glass and extruding the glass by the pressure through the perforations forming streams of glass. A stream of gas is directed upwa...

Beschreibung
Zusammenfassung:	A method of forming glass fibers includes maintaining heat-softened glass at a perforated planar area of a thin metallic plate, establishing pressure of the heat-softened glass and extruding the glass by the pressure through the perforations forming streams of glass. A stream of gas is directed upwardly into contact with the perforated area of the plate for transferring heat away from the plate at a temperature lower than the temperature of the heat-softened glass adjacent the plate to promote the delivery of discrete streams of glass from the perforations without flooding of the glass at the perforated planar area, and attenuating the streams of glass to fibers. Apparatus for carrying out the aforesaid method is also disclosed.
