Apparatus for processing chopped fibers from essentially continuous tows, each consisting of individual strands, comprises independently or selectively feeding at least two tows to a venturi pump and associated cutter mechanism where the tows are cut or chopped into relatively short lengths to form chopped fibers. The apparatus includes sensors for monitoring the movement of each of the tows to the pump and cutter mechanism, and a controller which adjusts the feed rate of the tows and the rate of operation of the cutter mechanism in the event movement of one of the tows varies from a predetermined feed rate.

[ It is claimed:] [1.] A cutter plate adapted for use in a cutter mechanism which forms chopped fibers from continuous tows comprising:a circular plate having first and second surfaces;said circular plate being formed with at least two ribs extending outwardly from said second surface thereof;said circular plate being formed with tow slot means, each extending from said first surface thereof through one of said ribs, said tow slot means each forming a straight shear edge along one of said ribs;said tow slot means being disposed about an axis through said plate such that said shear edges are disposed about said axis and extend in a direction other than radially with respect thereto;each said tow slot means for receiving and confining a plurality of fibers in one of said tows uniformly across said shear edges for shearing;one of said tows slot means each being adapted to receive a tow which passes therethrough and protrudes beyond said ribs extending from said second surface of said circular plate in position with respect to said straight shear edge of said ribs so that a cutter blade having a cutting edge parallel to said shear edges when shearing said fibers, can cut the tow against said shear edge to form chopped fibers.
