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

An attachable abrasive article comprises an abrasive member having an attachment device affixed thereto. The attachment device comprises a fastener having a flange thereon. Thermoplastic material is disposed between the flange and the abrasive article. The disclosure also concerns methods of making and using attachable abrasive articles.

Abrasive articles, and methods of making and using the same

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.

Method of making a surface treating article

A concatenation of circular abrasive discs each having a layer of abrasive material on a first surface, and means on a second surface for releasably attaching said discs to a drive member. The discs are attached to two adjacent discs at opposite edges by two narrow tabs along each edge spaced by at least 0.32 centimeter (1/8 inch) along the edge and generally equally spaced on opposite sides of a center line extending between the centers of the attached discs. Also the discs are separated between the tabs and the tabs are folded to position abrasive discs in a stack within a container with each abrasive disc in the stack having its layer of abrasive against the layer of abrasive of one adjacent disc, and its means for attaching adjacent the means for attaching of the other adjacent disc.
