ABSTRACT:
Apparatus for and the method of producing a sliver-like fibrous product including forming glass fibers, conveying the glass fibers in a body of gas and depositing them on the porous rim of a rotating wheel to form a coherent web, advancing the porous rim with the web thereon over an opening having a progressively reducing size in the direction of rim movement, establishing a zone of reduced pressure within the wheel to draw air through the fibers into the opening to progressively condense the web into a loosely associated longitudinal coherent sliver-like grouping of fibers, and discharging the longitudinal sliver-like fiber grouping from the rim.
