Abstract

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.

Claims

1. An apparatus for making a surface treating article, comprising:

a) attaching means for attaching a fastener to a surface treating web; and

b) cutting means for laser cutting the surface treating web around the fastener to provide a surface treating article.

2. An apparatus for making a surface treating article, comprising:

a) a spinwelder for attaching a fastener to a surface treating web;

b) a machine vision system to sense the position of the fastener on the surface treating web; and

c) a laser to cut the surface treating web around the fastener to provide a surface treating article with a fastener thereon.

3. The apparatus for making a surface treating article of claim 2, further including:

d) a web carrier for advancing the surface treating web.

4. An apparatus for making a plurality of surface treating articles, comprising:

a) a spinwelder for attaching a plurality of fasteners to a surface treating web, wherein each of the plurality of fasteners is located in a predetermined position forming an array of fasteners, and wherein the plurality of fasteners includes a first fastener, a second fastener, and a third fastener;

b) a machine vision system to sense a position of the first fastener and a position of the second fastener, wherein a position of the third fastener is determined relative to the positions of the first fastener and the second fastener; and

c) a laser to cut the surface treating web around each fastener to provide a surface treating article with a fastener theron.

5. The apparatus for making a plurality of surface treating articles of claim 4, further including:

d) a web carrier for advancing the surface treating web.
