A duct assembly is employed for directing a central air flow upwardly against the rotating spinner of a conventional fiberizer mechanism that produces a downwardly falling veil of fibers. The central air flow eliminates the low-pressure zone that normally occurs beneath the spinner assembly of conventional fiberizers. The central air flow is sufficiently cool to rapidly reduce the temperature of the fiber veil thereby to increase the tensile strength and elongation of the paper sheets produced from the fibers.
