12 Claims

1. An article of footwear up surface buffing system, the system comprising:

a rotational brush with a plurality of bristles extending outwardly from a rotational axis of the rotational brush;

a footwear component holder comprising a support surface, a first clamp, and a second clamp, wherein the first clamp is configured to move and press the article of footwear against the support surface in a vertical direction when in a clamped position, wherein the second clamp is configured to move and press the article of footwear against the support surface in a vertical direction when in a clamped position;

a brush rotational drive coupled with the rotational brush to rotate the rotational brush in first direction and in a second direction based on location of the rotational brush relative to the footwear component holder; and

a brush movement mechanism effective to move the rotational brush from a heel end to a toe end of the support surface, wherein the brush movement mechanism positions the rotational brush between a first distance and second distance offset from the support surface.
