Patent ID: 7731573

Claim:
A system for use in abrading a surface comprising: a power tool; a driving assembly coupled to the power tool; the driving assembly including a driving member having a major surface and an attachment mechanism for attachment to a conversion pad; a conversion pad having first and second opposing major surfaces, the first and second major surfaces of the conversion pad having an attachment mechanism, the first major surface is attached to the attachment mechanism of the driving member; a flexible abrasive article having first and second major surfaces, wherein the first major surface of the flexible abrasive article has an attachment mechanism; and an adapter body including opposing first and second major surfaces, wherein the second major surface thereof is adapted to be releasably attached to the flexible abrasive article and the first major surface of the adapter body is adapted to be releasably attached to the second major surface of the conversion pad; the adapter body including at least one stiffening portion that resists deformation of the flexible abrasive article when the stiffening portion directly supports the flexible abrasive article for modifying a working surface so that the flexible abrasive article substantially remains in an abrading plane while abrading, and the stiffening portion enables peeling of the flexible abrasive article from the adapter body.
