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.

Abstract: A heating apparatus at the end of a diaper production line composed of a series of radiant energy sources. These radiant energy sources are controlled so as to emit differing concentrations of radiant energy. The sources are controlled so as to emit radiant energy more absorbent by diaper polymer backing sheets in the first section of the heater and more absorbent by heat-shrinkable diaper elastics in the downstream portion of the heater. Further, the temperature of the heaters is preferably controlled to the desired infrared range by blowing hot air past the heaters and onto the diapers so as to provide conductive transfer and at the same time control the infrared radiant energy that is provided by the heaters.

Abstract: Ostomy collection pouch appliances suitable for operation in a first, non-vented, or second, vented but substantially leak-proof, mode and provided with a sealed port member including a heat seal configuration which provides the user with directional information concerning proper opening of the port.
