Abstract: A method and apparatus are provided for forming a fabric, suitable for mailing a finished composite product, using one or more composite strands. One embodiment of the apparatus comprises at least one bushing for forming reinforcing fibers; supply equipment for supplying matrix fibers; at least one applicator for applying bonding size (i.e., bonding chemical treatment) to the fibers; a gathering mechanism for gathering the treated fibers into at least one composite strand; a pulling mechanism for pulling the at least one composite strand; and a fabric forming mechanism for forming a fabric using the at least one composite strand.

Abstract: An apparatus is provided for producing a glass fiber package. The apparatus includes a heated bushing for supplying streams of molten glass to be drawn into continuous fibers, a rotatable member adapted to draw the streams into fibers and to wind the fibers into a package, an applicator for applying a size to the fibers, and a drying device including a heated element maintained at a temperature of between about 1000.degree. F. and 1500.degree. F. for contacting and transferring energy in the form of heat to the sized fibers to dry the fibers before they are wound into the package. The heating member is stationary while contacting the sized fibers.

Abstract: A sizing composition for glass is provided. The sizing composition comprises a vinyl acetate copolymer emulsion, a polyvinyl acetate copolymer latex, and a vinyl acrylic copolymer emulsion.

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.

Abstract: A method and apparatus is disclosed for producing dried sized glass fibers wherein a drying device is used to produce current flow along sized fibers to thereby partially or fully dry the size on the fibers. The apparatus may include an applicator for applying a size to the fibers and a drying device which comprises a high voltage electrode connected to a high voltage source and at least one grounded electrode. Drying is performed by passing the sized fibers by the electrodes such that a current flows along the sized fibers from the high voltage electrode to the at least one grounded electrode. The grounded electrodes may comprise grounded gathering shoes.
