ABSTRACT:
A method of preparing glass fiber strands is shown wherein the glass fibers as they are drawn from the glass fiber forming bushing are wound in a unique way. The fibers are drawn from the bushings using high speed, low energy drawing devices such as capstans and godets. They are then passed to high speed, low energy flyers for distribution onto the surface of light weight, low energy, slowing rotating mandrels. All the winding equipment and the attenuation devices are light in weight requiring very low horsepower motors compared to the high horsepower, high energy devices of the current state of the art. The flyers are shown driven by conventional motors or by a compressed air system. Collection of the strand takes place on the ends of the elongated mandrels shown and create a novel doughnut shaped forming package of fiber glass with properly distributed strands thereon suitable for unwinding.
