    Patent number: 5317913
    Abstract: This invention refers to an apparatus for determining the sag of a running web of material transversely to its longitudinal direction. For this purpose according to the invention a carrier of a web sensing roller is guided in a housing to be movable against spring force transversely to its rotational axis and apparatus is provided for measuring the displacement distance of the roller. The roller is replicated in triplicate across the width of the web. In other embodiments web sag is measured by roller rotation and by web force respectively on the three rollers.
