<p>An abrasive article is formed from a lofty nonwoven abrasive pad and one or more abrasive sheets. Each sheet has an abrasive layer on its front side and a plurality of engagement stems on its back side. Enough of the engagement stems engage fibers on the surface of the nonwoven pad to affix the two components together for workpiece surface treatment. The sheets are readily replaceable on the nonwoven pad, thus creating a very simple and versatile arrangement for varying the abrasive characteristics presented to the workpiece.</p> |
