Abstract

Die Erfindung betrifft eine Regeleinrichtung und ein Verfahren für die Regelung des Quer- und/oder Längsprofiles mindestens eines Qualitätsmerkmales beim Papierherstellungsprozeß mit Hilfe zweier Sensoren, wobei der erste Sensor (30) ein erstes Meßsignal des Quer- und/oder Längsprofiles eines ersten Qualitätsmerkmales der produzierten Papierbahn aufnimmt und ein zweiter Sensor (31) ein weiteres Meßsignal aufnimmt. The invention relates to a control device and a method for the control of the transverse and / or machine direction profile of at least one quality feature in the paper manufacturing process with the aid of two sensors, the first sensor (30) a first measurement signal of the transverse and / or machine direction profile of a first quality feature of the produced receiving the paper web and a second sensor (31) receives a further measurement signal.
Die Erfindung ist dadurch gekennzeichnet, daß der weitere Sensor (31) zur Aufnahme eines anderen Qualitätsmerkmals als der erste Sensor (30) geeignet ist beziehungsweise dieses andere Qualitätsmerkmal mißt. The invention is characterized in that the further sensor (31) for receiving a quality feature other than the first sensor (30) is adapted or measures that other quality feature.
