Abstract:
The invention provides a substantially flat coated abrasive article having a fabric-reinforced backing which may include engaging elements such as hooks for releasable attachment to the surface of an abrading apparatus and a method of making the article. The invention also provides an abrading apparatus which includes a back-up pad having releasably attached thereto the abrasive article. The article comprises a substantially flat sheet-like substrate comprised of thermoplastic material and a porous fibrous reinforcing element contained within the substrate and an abrasive layer disposed on a surface of the substrate.
