Apparatus and method for drawing of glass fiber |
摘要 |
An apparatus and method for use 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. A selectively adjustable bulk gas nozzle has a plurality of discharge conduits with valves therein which are adjustable and capable of being selectively operated to close the conduits or return the conduits to a preset open condition. The nozzle and/or a binder applicator are supported for select movement toward and away from the path of the fiber being drawn from the orifice plate. A detector senses the presence of fiber being drawn from the orifice plate and, in the event of fiber break-out, initiates a series of steps to warn the operator of the bushing assembly and, in the event the break-out condition is not corrected, shut down the drawing operation.
