ABSTRACT:
This is an improvement to current processes and apparatus for producing monofilament glass fibers from a single or a multitude of streams of molten or plastic glass, being drawn through an orifice feeder into fibers and collected on a winder. A speed control is provided to the winder motor, to alter the speed of the motor in response to a change in temperature of the orifice, or to an interruption in the drawing process. The result is that at start-up after an interruption or with a drop in temperature at the orifice, the monofilament strands are of constant diameter. A predetermined time after start-up or when the temperature of the orifice changes, the speed control changes the rate of drawing the monofilaments and the diameter of the monofilaments are maintained consistent subsequent to an interruption to the process or when the temperature of the orifice changes.
