    Abstract: This specification discloses fiber additives for reinforcing matrix materials and an apparatus for forming the same, said fibers having flattened shanks terminated with egg-shaped nodules. The apparatus comprises a roller-former-cutter assembly that forms the fibers in a single operation from continuous filaments using compressive force and a unique cut-out and blade assembly. The fibers described are designed to have an increased pull-out resistance compared to other fiber morphologies.
