ABSTRACT OF THE DISCLOSURE The present invention relates to the manufacture of fibrous wool by the rotary process. In the rotary process heat softenable material, such as molten glass, is supplied to a centrifuge wherefrom streams of the heat softenable material emanate and are acted upon by a fiber attenuating high velocity gaseous medium located about the periphery of the centrifuging means. A cylindrically shaped veil of high velocity gases having attenuated fibers contained therein flows axially away from the centrifuging means to a suitable collecting means. Improved method and apparatus are provided for distributing the entrained fibers upon the collecting means. The cylindri- cally shaped veil is intermittently acted upon by finite sheets of high velocity gas thereby interrupting the otherwise columnar flow of the cylindrical veil and establishing diverging flows of fibers. There are preferably a pair of oppositely directed pulsating sheets each having modulated progressively ascending and descending pressure wave forms. By the intermittent action of the gaseous planes upon the cylindrical veil a randomly uniform distribution of fibers upon the collecting means is realized.
