Abstract
A fiber cutting device is disclosed having a cutting head with one or more blades disposed across a surface of the cutting head and disposed to rotate about a cutting head axis. An anvil roller is disposed and driven to rotate about an anvil axis and has a surface in momentary contact with each the one or more blades of the cutting head. Fibers are delivered to the device across a feeder. A feed control toggle may be moved to a stop position, where a first end of the feed control toggle presses the plurality of fibers against the feeder to stop motion of the fibers and prevent cutting. Contact with the anvil roller to draw the fibers between the cutting head and the anvil may also be controlled by the feed control toggle. A flap for sliding contact between the fibers and the anvil may also be used.
Claims20
A fiber cutting apparatus, comprising:
- a cutting head disposed to rotate about a cutting head axis and having one or more blades disposed across a surface of the cutting head;
- an anvil roller disposed adjacent to the cutting head to rotate about an anvil axis and to have a surface in momentary contact with each of the one or more blades of the cutting head;
- a feeder for delivering a plurality of fibers between the cutting head and the anvil roller;
- a movable member that moves between a stop position, where the movable member is disposed proximate to the feeder for pressing the plurality of fibers against the feeder to stop motion of the plurality of fibers and prevent cutting, and a cutting position, where the movable member is disposed distal to the feeder for releasing the plurality of fibers from the feeder so that the plurality of fibers can be drawn into the momentary contact with each of the one or more blades of the cutting head;
- and
- a flap for pressing the plurality of fibers against the surface of the anvil roller such that the surface of the anvil roller draws the plurality of fibers to be cut into the momentary contact with each of the one or more blades of the cutting head only with the movable member in the cutting position.

- an anvil roller disposed adjacent to the cutting head to rotate about an anvil axis and to have a surface in momentary contact with each of the one or more blades of the cutting head;
- a feeder for delivering a plurality of fibers between the cutting head and the anvil roller;
- a movable member that moves between a stop position, where the movable member is disposed proximate to the feeder for pressing the plurality of fibers against the feeder to stop motion of the plurality of fibers and prevent cutting, and a cutting position, where the first end of the movable member is spaced from the feeder for releasing the plurality of fibers from the feeder so that the plurality of fibers can be drawn into the momentary contact with each of the one or more blades of the cutting head;
- and
- a flap for providing a sliding contact for pressing the plurality of fibers against the surface of the anvil roller such that the surface of the anvil roller draws the plurality of fibers to be cut into-the momentary contact with each of the one or more blades of the cutting head and the anvil roller.

A method of cutting fibers, comprising:
- disposing a cutting head to rotate about a cutting head axis, the cutting head having one or more blades disposed across a surface of the cutting head;
- rotating an anvil roller disposed adjacent to the cutting head about an anvil axis, the anvil roller having a surface for being in momentary contact with each of the one or more blades of the cutting head;
- delivering a plurality of fibers between the cutting head and the anvil roller with a feeder;
- pressing the plurality of fibers against the surface of the anvil roller with a flap such that the surface of the anvil roller draws the plurality of fibers to be cut into the momentary contact with each of the one or more blades of the cutting head and the anvil roller only with a movable member in a cutting position;
- and
- moving the movable member between a stop position, where the movable member presses the plurality of fibers against the feeder to stop motion of the plurality of fibers to prevent cutting, and the cutting position, where the movable member releases the plurality of fibers from the feeder so that the plurality of fibers can be drawn into the momentary contact with each of the one or more blades of the cutting head.
