Method and apparatus for producing glass fibers or filaments

摘要

The disclosure embraces a method of and apparatus for controlling or stabilizing the temperature or heat pattern at an orifice plate or feeder floor from which flow glass streams which are attenuated to fibers or filaments. More particularly the disclosure embraces a method of and apparatus for delivering streams of air or other fluid from a nozzle construction at a selected angular position into the attenuating environment and onto the feeder floor or orifice plate for cooling the glass streams and the feeder floor or orifice plate for normal attenuating operations. In event of a fiber or filament break-out or other interruption of attenuation, the angularity of the nozzle construction is changed with respect to the normal path of movement of the fibers or filaments so as to stabilize the heat pattern at the orifice plate or feeder floor and thereby facilitate restarting of normal attenuating operations.
