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.

A method for forming one or more composite strands comprising the steps of: drawing a plurality of glass first fibers from a source of molten glass; providing a supply of one or more second fibers of a second material; applying a size to said first and second fibers; contacting said sized first and second fibers with a heated member to effect drying of said size on said first and second fibers, said contacting of said sized first and second fibers with said heated member occurring in-line with said drawing of said first fibers; and gathering said first and second fibers into one or more composite strands.
