Abstract
Attempts have been made by the prior art to oscillate a veil of air entrained centrifugally spun fibers back and forth across a moving collecting surface to build a layer of fibers having uniform thickness and density. The present invention accomplishes this objective by oscillating a fiberizing rotor, preferably about an axis that runs through the bottom wall of the spinner.
