  • Apparatus for making a surface treating article
    Patent number: 7182682
    Abstract: 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.

  • Surface treating member having a fastener
    Publication number: 20030114096
    Abstract: A surface treating article including a surface conditioning member, a fastener including a generally planar surface and a drive member, and a layer of adhesive between the surface conditioning member and the planar surface of said fastener, where the layer of adhesive includes rotational orientation. The present invention also provides a preferred method of attaching a fastener to a surface conditioning member that includes inducing relative rotation between a fastener and a surface conditioning member with a layer of adhesive in contact with a planar surface of the fastener and the surface conditioning member so as to soften the layer of adhesive and thereafter stopping the relative rotation between the fastener and the surface treating member.
