ABSTRACT:
Disclosed is an apparatus and method for separating clumps of resilient fibers such as aramid polymer fiber agglomerates. Rotating blades throw the fiber clumps outwardly against a surrounding resilient "cushion" of fibers of the material. Rather than physically cutting or chopping the fibers, the blade tips exert a rubbing or dissecting action on the clumps. The separated fibers are swept to an outlet by an airstream, while unseparated fibers in the cushion are urged toward the blades for further separation. It is an important advantage of the invention that the average length of the fibers is not substantially reduced as the clumps are being separated by the blades.
