An apparatus for making a surface treating article, and in one embodment for making a plurality of surface treating articles. The apparatus includes an attaching means for attaching a fastener to a surface treating web and a cutting means for cutting the web around the fastener to provide a surface treating article. In one embodiment, a sensor, such as a machine vision system, senses a position of the fastener on the web, with this sensed position being used to direct operation of the cutting means.

Apparatus for making a surface treating article

A back-up pad for supporting an abrasive article is disclosed. The back-up pad includes an engagement assembly bonded to a first major surface. The engagement assembly includes a first region including a plurality of first engagement means having a first durability. The engagement assembly also includes a second region including a plurality of second attachment means having a second durability. The first engagement means have a substantially higher durability than the second engagement means.

Engaging assembly for abrasive back-up pad

Abrasive article including a backing plate. Backing plate has a first major surface and a second opposite major surface. A central aperture extends through backing plate. An abrasive layer is secured to the first major surface of backing plate. A fastener is press fit to backing plate so as to define the central aperture.

Abrasive article

A surface treating article including a surface treating member and a fastener including a fiducial. The present invention also provides a preferred method of making a surface treating article that includes to a method of sensing the location of a fasteners on a surface treating web and thereafter cutting the surface treating web around the fastener to provide a surface treating article.
