A control system for use in combination with a bushing assembly of the type wherein glass fibers are drawn through an orifice plate having a flat undersurface against which bulk gas is directed to effect cooling and fiber attentuation. The system controls operation in the event of fiber "break out", by lowering the temperature of the bushing assembly, increasing the rate of flow of bulk gas against the orifice plate, controlling the drawing action of the collet used to draw fibers from the plate, and spraying cooling water against the fibers being drawn from the plate. Control is effected through means of a common main control unit and manual controls are provided to permit operation of the control system to selectively control the operating mode of the system and increase the bulk flow of gas for orifice plate clearing purposes. |
