Abstract

Aspects of the present disclosure relate to an abrasive assembly and a method of making an abrasive assembly. The method can include receiving a segmented adhesive-backed abrasive article that includes a release liner and a plurality of abrasive segments disposed on the release liner. Each abrasive segment comprises a segment abrasive layer and a segment adhesive layer that each have a smaller planar surface area than a planar surface area of an adhesive-backed abrasive sheet. The release liner of the segmented adhesive-backed abrasive article is continuous and connects the plurality of abrasive segments which are discrete from each other. The method can include applying transfer film assembly to the segmented adhesive-backed abrasive article. A second adhesive layer of the transfer film assembly adheres to the segment abrasive layer and the segment abrasive layer is sandwiched between the segment adhesive layer of a first adhesive layer and the second adhesive layer.
