Abstract: Abstract of the Disclosure An improvement is disclosed in an apparatus for forming glass fibers comprising a bushing having a plurality of bushing  tips through which fila-ments are attenuated, an applicator having an application surface thereon for applying binder and size to the filaments, a gathering shoe to combine the filaments into unified strand, and means for collecting strand containing binder and size, and the improvement comprises a cover for the applicator, means associated with the cover to remove filaments from the application surface of the applicator during attenuation of waste strand by movement of the cover over the applicator so that waste filaments are not coated with binder and size when the cover is moved over the applicator but are still permitted to run.  With the apparatus, the glass filaments are brought into contact with the application surface for coating the filaments with a binder and/or size only when production quality strand is being produced.  This substantially reduces binder and/or size consumption and prevents the operator of the forming position from coming into physical contact with the binder and/or size coated strand.
