ABSTRACT:
A method and apparatus are provided for producing composite strands. The apparatus comprises a heated bushing for supplying streams of molten glass to be drawn into continuous first fibers; a drawing device adapted to draw the streams into the first fibers; supply equipment for supplying one or more second fibers of a second material; one or more applicators for applying a size to the first and second fibers; and a device for gathering the first and second fibers into one or more composite strands. The composite stands are made by drawing glass fibers from the bushing; applying sizing to the glass fibers and the second fibers; contacting the fibers with a heated contact plate to dry the fibers; and then commingling the fibers to form one or more composite strands.
