Abstract

Eine Vorrichtung zum Regeln der Spannung in einer Bahn (120) einer Druckmaschine umfaßt eine Tänzerwalze (20), die regelbar positionierbar und mit einem Luftzylinder 30) verbunden ist. An apparatus for controlling the tension in a web (120) of a printing machine includes a dancer roller (20) which is connected to adjustable positionable an air cylinder 30). Die Tänzerwalze (20) kommt mit der Bahn (120) in Kontakt, und zwar an einer Stelle, die sich hinter den Zugwalzen (6, 7) am Ausgang der Kühleinheit und vor dem nächsten Zugwalzenpaar (9) am Eingang der Längsschneideeinheit befindet. The dancer roller (20) comes with the web (120) in contact, and at a location that is behind the draw rollers (6, 7) at the output of the cooling unit and before the next pair of drawing rollers (9) located at the entrance of the slitter unit. Der Luftzylinder (30) beaufschlagt die Tänzerwalze (20) mit einer Ausgleichskraft, so daß der Kontakt zwischen der Tänzerwalze (20) und der Bahn (120) bestehen bleibt. The air cylinder (30) acts on the compensating roller (20) having a balancing force, so that the contact between the dancer roller (20) and the web (120) remains. Eine Steuereinheit (90) ist mit der Tänzerwalze (20) und dem nächsten Zugwalzenpaar verbunden. A control unit (90) is connected to the dancer roller (20) and the next pair of drawing rollers. Die Steuereinheit (90) überwacht die Position der Tänzerwalze (20) und erhöht oder verringert die Geschwindigkeit des nächsten Zugwalzenpaares je nach Richtung und Größe der Bewegung der Tänzerwalze (20). The control unit (90) monitors the position of the dancer roller (20) and increases or decreases the speed of the next pair of drawing rollers, depending on the direction and magnitude of movement of the dancer roller (20). Auf diese Weise wird die Spannung in der Bahn (120) zwischen den Zugwalzen (6, 7) am Ausgang der Kühleinheit und dem nächsten Zugwalzenpaar im wesentlichen konstant gehalten. In this way, the tension in the web (120) between the drawing rollers (6, 7) is kept constant at the output of the cooling unit and the next pair of drawing rollers substantially.
