ABSTRACT:
The invention relates to apparatus and method for producing fibers from heat-softened mineral material, such as glass. More specifically, this invention relates to method of, and apparatus for, producing glass fibers from an electrically heated bushing having a bottom wall with an orifice section for delivery of glass streams for attenuation into fibers comprising sensing the temperature at the orifice section, supplying a signal that varies in response to the sensed temperature and indicating that a disruption in fiber production has occurred when the supplied signal is outside a predetermined range.
