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.

Method of 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:
- a. attaching a temperature sensing means to the bushing bottom wall in the orifice area;
- b. sensing the temperature at the orifice section;
- c. supplying a signal that varies in response to the sensed temperature;
- and
- d. indicating that a disruption in fiber production has occurred when the supplied signal is outside a predetermined range.
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:
- a. a temperature sensing means attached to the bushing bottom wall in the orifice area for sensing the temperature at the orifice section;
- b. means for supplying a signal that varies in response to the sensed temperature;
- and
- c. means for indicating that a disruption in fiber production has occurred when the supplied signal is outside a predetermined range.
Method of producing glass fibers from a bushing having a bottom wall with an orifice section for delivery of glass streams for attenuation into fibers comprising;
- a. attaching at least two temperature sensing means to the bushing bottom wall at spaced-apart locations in the orifice area;
- b. sensing temperatures of the orifice section at spaced-apart locations;
- c. supplying a signal for each location which varies in response to the sensed temperature at each location;
- and
- d. indicating that a disruption in fiber production has occurred when any of the supplied signals indicate that the sensed temperature at any location is outside a predetermined temperature range.
