Abstract
A cutting apparatus for hair or fiber protruding from a surface includes a roller, a number of cutting features disposed at an outer peripheral surface of the roller, wherein the number of cutting features is adapted for cutting the hair or fiber when the roller rotates in contact with the filamentous surface or is moved while in contact with the filamentous surface.
Claims20
A cutting apparatus comprising:
- a roller;
- and
- a plurality of cutting features disposed at an outer peripheral surface of the roller,
- wherein the plurality of cutting features are adapted for cutting filamentous protrusions on a filamentous surface when the roller rotates in contact with the filamentous surface,
- wherein one or more of the plurality of cutting features comprises opposing cutting edge surfaces forming a sharp-edged aperture in the peripheral surface of the roller, and
- wherein the sharp-edge aperture is a normally closed slit which is configured to open when a pressure is applied to a portion of the roller to deform the roller to conform to the filamentous surface and returns to the normally closed configuration when the portion of the roller returns to an undeformed condition.

A cutting device comprising:
- a support member;
- and
- a cutting apparatus, comprising:
- a roller;
- a plurality of cutting features disposed at an outer peripheral surface of the roller;
- and
- a cutting bar at a first end of the support member in cutting contact with the cutting apparatus, wherein the plurality of cutting features are adapted for cutting filamentous protrusions on a filamentous surface when the roller rotates in contact with the filamentous surface,
- wherein one or more of the plurality of cutting features comprises opposing cutting edge surfaces forming a sharp-edged aperture in the peripheral surface of the roller, and
- wherein the sharp-edged aperture is a normally closed slit which is configured to open when a pressure is applied to a portion of the roller to deform the roller to conform to the filamentous surface and return to the normally closed configuration when the portion of the roller returns to an undeformed condition, and
- wherein the support member supports the cutting apparatus for rotation.
