Abstract

Beschrieben wird ein Korrugator zum Herstellen von Rohren mit einer querprofilierten Rohrwandung mit Formbacken (101 bis 110), die entlang mindestens zweier Umlaufbahnen bewegt werden. Die Umlaufbahnen sind so ausgebildet, dass sie jeweils einen Arbeitsabschnitt (135) und einen Rückführungsabschnitt aufweisen. In ihrem Arbeitsabschnitt (135) führen die Umlaufbahnen die Formbacken (101 bis 110) unter Ausbildung eines gemeinsamen Formkanals. In den Rückführungsabschnitten erfolgt jeweils eine über eine Rückführungseinrichtung gesteuerte Rückführung der Formbacken (101 bis 110). Wesentlich ist, dass mindestens zwei in einer Umlaufbahn hintereinander angeordnete Formbacken unterschiedliche Länge aufweisen. Zur Steuerung des Formbackenantriebs ist eine Erfassungseinrichtung (141, 142) zur Erfassung eines Ist-Zustands der in den Umlaufbahnen geführten Formbacken (101 bis 110) vorgesehen. Die Steuerung erfolgt über eine elektronische Steuerungseinrichtung.
