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.
Claims19
A cutter head assembly for a fiber roving chopper, the cutter head assembly comprising:
- a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end, the cylindrical blade cartridge comprising:
- a first body having a base at the cartridge first end and a finger extending from the base toward the cartridge second end, the finger having a first surface angled with respect to a central axis of the cylindrical blade cartridge;
- and
- a second body having a second surface that is angled with respect to the central axis, wherein the second body is configured to receive and mate with the finger of the first body such that the second surface opposes the first surface and is parallel to the first surface;
- and
- a blade extending between the cartridge first end and the cartridge second end and disposed between the first surface of the first body and the second surface of the second body.
A cutter head assembly for a fiber roving chopper, the cutter head assembly comprising:
- a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end, the cylindrical blade cartridge comprising:
- a first body having a first plurality of circumferentially spaced fingers, each of the first plurality of fingers having a first surface angled with respect to a central axis of the cylindrical blade cartridge;
- and
- a second body having a second plurality of circumferentially spaced fingers, each of the second plurality of fingers being disposed between two of the first plurality of fingers and having a second surface angled so as to oppose one of the first surfaces of the first plurality of fingers;
- and
- a plurality of blades extending between the cartridge first end and the cartridge second end, each blade being disposed between one of the first surfaces of the first plurality of fingers and one of the second surfaces of the second plurality of fingers.
A cutter head assembly for a fiber roving chopper, the cutter head assembly comprising:
- a cylindrical blade cartridge extending axially between a cartridge first end and a cartridge second end, the cylindrical blade cartridge comprising:
- a first body comprising a first base at the cartridge first end and a first finger extending from the first base toward the cartridge second end, the first finger having a first surface extending between the cartridge first and second ends and angled with respect to a central axis of the cylindrical blade cartridge;
- and
- a second body comprising a second base at the cartridge second end and a second finger extending from the second base toward the cartridge first end, the second finger having a second surface extending between the cartridge first and second ends parallel to the first surface, wherein the second finger of the second body is configured to mate with the first finger of the first body such that the second surface faces the first surface;
- and
- a blade body extending between the cartridge first end and the cartridge second end and disposed between the first surface and the second surface.
