Publication number: 20030010460Abstract: In a method of monitoring the state of a felt serving for the dewatering of a fiber web, in particular of a paper web or of a cardboard web, the felt topography is measured and/or an image of the felt surface having definition in depth is produced by mean of an optical measuring device and the result of the measurement obtained is compared with previously stored error patterns by means of an evaluation and/or control unit. Corresponding felt conditioning measures are then initiated, preferably automatically, in dependence on the result of the comparison. A corresponding felt monitoring device is also described. In a further method of monitoring the state of a felt or screen serving the dewatering of a fiber web, in particular of a paper web or a cardboard web, specific felt and/or screen properties are determined permanently or cyclically at intervals and are filed under a pre-settable felt and/or screen name in a historical database.Type: ApplicationFiled: July 12, 2002Publication date: January 16, 2003Inventors: Joachim Grabscheid, Ulrich Begemann, Oswald Satzger, Wolfgang Mayer, Ralf Rziha, Wolfgang Bamberger, Georg Kleiser, Thomas Ruhl
