Abstract

See full text

An abrasive sheet article is disclosed, including a substrate having first and second major surfaces, a coated abrasive on the first major surface, and a plurality of hooking stems on the second major surface. The coated abrasive may comprise a plurality of precisely shaped composites comprising a plurality of abrasive grains dispersed in a binder. The hooking stems are adapted to hook engaging structures on an opposed surface to releasably affix the abrasive sheet member to the surface. A method for making such abrasive articles is also disclosed, including several illustrative variations of the inventive method. Also disclosed is a back-up pad for supporting such an abrasive article during abrading. The back-up pad includes a support portion, such as a polymeric backing, and an engaging portion, such as a loop material, for engaging hooking stems projecting from the abrasive article.
