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;
- and
- a feed control toggle that moves between 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 plurality of fibers and prevent cutting and a cutting position where the first end of the feed control toggle releases the plurality of fibers to be drawn into the momentary contact with each of the one or more blades of the cutting head;
- wherein the plurality of fibers are pressed against the surface of the anvil roller such that the surface of the anvil roller draws the plurality of fibers to be cut between the momentary contact with each of the one or more blades of the cutting head and the anvil roller only with the feed control toggle in the cutting position.
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 plurality of fibers between the cutting head and the anvil roller;
- and
- a flap for providing a sliding contact 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 between 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 in momentary contact with each of the one or more blades of the cutting head;
- delivering 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 such that the surface of the anvil roller draws the plurality of fibers to be cut between the momentary contact with each of the one or more blades of the cutting head and the anvil roller only with the feed control toggle in the cutting position;
- and
- moving a feed control toggle between 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 plurality of fibers to prevent cutting and a cutting position where the first end of the feed control toggle releases the plurality of fibers to be drawn into the momentary contact with each of the one or more blades of the cutting head.
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 in momentary contact with each of the one or more blades of the cutting head;
- delivering plurality of fibers between the cutting head and the anvil roller with a feeder;
- and
- pressing the plurality of fibers against the surface of the anvil roller with a flap providing a sliding contact with the plurality of fibers such that the surface of the anvil roller draws the plurality of fibers to be cut between the momentary contact with each of the one or more blades of the cutting head and the anvil roller.
