A method of making a roll of adhesive tape that comprises providing a length of tape having a leading end, a trailing end, a first side, and a second side opposite the first side, wherein the second side of the tape is at least partially covered with pressure sensitive adhesive and providing a tab having first and second opposite ends having a length between them, a first side, and a second side, wherein at least a portion of the second side of the tab is covered with pressure sensitive adhesive. The method further comprises advancing the length of tape along a tape path, positioning the leading tape end about a central tape roll axis, and circumferentially winding the length of tape about the axis until a penultimate tape layer having a circumference is wound. The adhesive-covered portion of the second side of the tab is applied to the first side of the tape so that the first end of the tab is spaced from the trailing end of the tape length by a predetermined distance that is at least as long as the circumference of the penultimate layer of the tape roll and no longer than a total distance of the circumference of the penultimate layer and the length of the tab. The final layer of the tape length is circumferentially wound around the penultimate tape layer so that the trailing end of the tape overlays the tab between the first and second ends of the tab.

Tape roll tab application method and article

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 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.
