ABSTRACT:
A one-piece abrasive sheet and method of manufacture. The abrasive pad has a planar sheet portion with a plurality abrasive protrusion extending therefrom. The protrusions are intimately molded with the planar sheet portion to form a one-piece sheet. Thermoplastic and abrasive grit mixture may be used to form the sheet. The resulting pad has improved durability.
Also disclosed is an improved circumferentially outer lip structure with a ramp surface for improving performance of the pad over irregular surfaces or surfaces with edges or steps or the like.
