Title: Apparatus for gathering fibers into a plurality of spaced apart strands

Abstract: An apparatus for gathering individual glass fibers into spaced apart strands is disclosed. The individual fibers, during formation are passed over an applicator which applies a lubricant to the fibers. A circular cylindrical bar member, at an oblique angle to the application surface, contacts the spaced apart strands, and in conjunction with a cylindrical free wheeling roller, causes the fibers to be consolidated into a plurality of spaced apart strands according to the natural filament split.
