Abstract
An abrading apparatus formed from sheet stock and processes for making the same are disclosed. The abrading apparatus has a base with a plurality of cantilevered members extending from the periphery of the base with each cantilevered member formed to provide a discontinuous abrading surface along the periphery of the apparatus. A process for making this abrading apparatus includes the steps of forming from a single piece of sheet stock a base having a plurality of cantilevered members, positioning the cantilevered members at an angle relative to the plane of the base, and forming the cantilevered members to provide exterior surfaces upon which an abrasive surface may be provided.
Claims3
An abrading tool comprising:
- a rotatable and generally planar and circular hub having a central aperture and a plurality of integral and radially extending generally loop-shaped members;
- each said loop-shaped member being positioned in a plane disposed at an oblique angle to the plane of said hub;
- each said loop-shaped member having an outer elongated abrading surface disposed at said oblique angle, and an opposed inner surface;
- and said loop-shaped members being spaced to provide air access to said inner surface during rotation of said abrading tool.
