Abstract
Method and apparatus for forming discrete segments of fibrous glass comprises supplying a plurality of streams of molten glass; attenuating the streams into filaments and cutting the continuous filaments into discrete segments by a forming means; positioning a delivery means having a first collection zone and a second collection zone spaced from the first zone to receive said discrete segments; controlling said forming means to operate at a first speed or a second speed slower than the first speed; directing the discrete segments to said first zone when said forming means is operated at said first speed and to said second zone when said forming means is operated at said second speed.
