ABSTRACT:
An apparatus for the production of mineral fiber or wool felts, blankets or batts having uniform thickness and density, comprising means for fiberizing the mineral composition, a housing defining a chamber into which the fibers are introduced, a foraminous belt upon which the fibers are deposited, a rotating brush for sweeping or throwing back excess fibers, thereby leaving a uniform layer of uncompressed fibers on the felt, and a roller for compressing the layer of fibers into a felt. The rotary brush removes the excess fibers and cooperates to provide a felt which is of uniform density and thickness.
