ABSTRACT:
Fiberglass filament hulls are cut to form fiberglass staple fibers with an apparatus comprising a cutting roller with a plurality of equally spaced, circular, diamond coated cutting blades separated by circular spacers having a diameter less than the diameter of the cutting blades; a circumferentially grooved pressure roller positioned parallel to the cutting roller and forming a nip therewith, with the periphery of the blades extending in non-engaging relation into the grooves; and a conveyor for flattening and conveying the hulls into the nip of the cutting and pressure rollers with the hull filaments being oriented substantially transverse to the blades while the cutting roller is rotated at a significantly greater speed than the pressure roller, whereby the hull filaments are held against the cutting roller by the pressure roller, and cut into staple fiber lengths by the blades.
