摘要

Replaceable blades have an inner generally planar portion which is mounted between imperforate spacers of a tire buffing machine hub and an outer working edge portion which protrude beyond said spacers. Said working edge portion has spaced teeth and means in the form of apertures located adjacent the base of the teeth and outwardly of the perimeter of said spacers for collection and direction of air and/or externally applied moisture in rotation of the hub. In some of the disclosed forms the trailing edge of the apertures is embossed or otherwise scoop shaped for increased collection capability and/or capacity.
