Abstract
A method and apparatus for collecting fibrous material, particularly small diameter glass fibers, i.e. within the range of 0.05 to 2.60 microns, from a gaseous medium in an efficient, environmentally sound manner is disclosed herein. The apparatus includes a collection chamber which partially encloses a rotating drum having a perforated peripheral surface and having a fine mesh collection screen superimposed thereover. The drum is positioned in such a manner that the screen intercepts a gaseous stream of fibers, e.g. glass microfibers. A suction force established interiorly of the peripheral surface of the drum draws the gaseous stream through the collection screen in order to thereby continuously collect a layer of fibers upon a portion of the rotating screen. The layer of fibers is removed from the drum and wound on a mandrel at a point outside the collection chamber. In a preferred embodiment of the present invention the drum surface is cleaned of any residual fibers.
