Abstract
A cutter head assembly for a fiber roving chopper includes a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end. The cylindrical blade cartridge includes a first surface that extends between the cartridge first and second ends and is angled with respect to a central axis of the cylindrical blade cartridge. A second surface extends between the cartridge first and second ends parallel to the first surface and the second surface faces the first surface. A blade body extends between the cartridge first end and the cartridge second end and is disposed between the first surface and the second surface.
