    Patent number: 4837715
    Abstract: The present invention provides an apparatus for examining a moving web composed of an interconnected plurality of articles to determine a location of a selected component thereof. The apparatus includes an indicating mechanism for providing marker data corresponding to the presence of a selected article. A metering mechanism generates gauge data corresponding to selected incremental lengths along the article in the movement direction of the web. A designating mechanism provides reference data corresponding to a selected reference point on the article, and a locating mechanism detects position data corresponding to a position of a selected component of the article. An evaluating mechanism processes the reference data, location data and gauge data to determine a spaced distance between the component and the reference point.
