ABSTRACT:
A method and apparatus for distributing fibrous material includes establishing a flow of fibrous material, positioning at least two flow distributors in a position to direct a gaseous flow into contact with the flow of fibrous material, such as a flow of glass fibers, each flow distributor having an outer surface having one or more openings for the emission of gas, an inner surface having one or more orifices for the emission of gas, and a pressurized source of gas in contact with the inner surface, the inner surface being moveable with respect to the outer surface to intermittently align some of the openings with some of the orifices, thereby enabling gas from the pressurized source of gas to be emitted through the inner and outer surfaces and into contact with the flow of fibrous material to distribute the fibrous material, and moving one of the surfaces relative to the other of the surfaces to control the emission of gas from the flow distributor.
