Abstract

Zum Planrichten von Papierbahnen (3) sind Durchlaßspalte (20) vorgesehen, welche jeweils von einer Umlenkwalze (17) und einer stationären Richtfläche (16) begrenzt sind, wobei zur Änderung des Umschlingungswinkels an der Richtfläche (16) wie auch zum unbearbeiteten Durchlauf des Lagenmateriales (3) durch die Vorrichtung (1) die Umlenkwalze (17) mit einer Stellvorrichtung (30) motorisch in unterschiedliche Stellungen überführbar ist. Dadurch ergibt sich bei einfachem Aufbau eine schnelle Arbeitsweise sowie eine sichere Funktion.
