Abstract

Die Erfindung betrifft Verfahren zum Betrieb einer Rollendruckmaschine. Einerseits wird eine Bedruckstoffbahn (01) von einem Einzugswerk (02) in die Rollendruckmaschine eingezogen und von einer in Transportrichtung der Bedruckstoffbahn (01) nach einer zu dieser Rollendruckmaschine gehörenden Druckeinheit (11) angeordneten Zugwalze (03) gezogen, wobei die Zugwalze (03) von einem steuerbaren oder regelbaren Motor (04) angetrieben wird, wobei das Einzugswerk (02) und der Motor (04) der Zugwalze jeweils von einer Steuereinheit (06) gesteuert oder von einer Regeleinheit (06) geregelt werden, wobei von der den Motor der Zugwalze (03) steuernden Steuereinheit (06) oder von der den Motor der Zugwalze (03) regelnden Regeleinheit (06) ein Messwert (MA) hinsichtlich eines von diesem Motor ausgeübten, an der Bedruckstoffbahn (01) als Zugkraft angreifenden Antriebsmomentes erfasst wird, wobei dieser Messwert (MA) der das Einzugswerk (02) steuernden Steuereinheit (06) oder der das Einzugswerk (02) regelnden Regeleinheit (07) zur Verfügung gestellt wird, wobei die Rollendruckmaschine in ihrem Hochlauf in Abhängigkeit von diesem ermittelten Messwert (MA) gesteuert oder geregelt wird. Andererseits wird eine Bedruckstoffbahn (01) von einem Einzugswerk (02) und/oder einer in Transportrichtung der Bedruckstoffbahn (01) nach einer zu dieser Rollendruckmaschine gehörenden Druckeinheit angeordneten Zugwalze (03) mit einer einstellbaren Geschwindigkeit in die Rollendruckmaschine eingezogen, wobei die Einstellung der Geschwindigkeit des die Bedruckstoffbahn (01) in die Rollendruckmaschine einziehenden Einzugswerks (02) in Abhängigkeit von einer an der Bedruckstoffbahn (01) angreifenden Zugkraft erfolgt, wobei die Zugkraft in der Bedruckstoffbahn von einem Antriebsmoment eines Motors der Zugwalze ausgeübt wird, wobei die Bedruckstoffbahn (01) vor dem Erreichen eines Mindestwertes für das vom Motor der Zugwalze (03) ausgeübte, an der Bedruckstoffbahn (01) als Zugkraft angreifende Antriebsmoment mit einer gegenüber einer sonst zulässigen Geschwindigkeit verringerten Geschwindigkeit eingezogen wird.

The invention relates to methods for operating a web-fed printing machine. On the one hand, a printing material web (01) is drawn into the web press from an infeed unit (02) and pulled by a draw roller (03) arranged in the transport direction of the printing material web (01) according to a printing unit (11) belonging to this web press, wherein the draw roller (03) is driven by a controllable or controllable motor (04), wherein the feed mechanism (02) and the motor (04) of the tension roller are each controlled by a control unit (06) or controlled by a control unit (06), of which the motor of Zugwalze (03) controlling control unit (06) or from the motor of the tension roller (03) regulating control unit (06) a measured value (MA) is detected with respect to a force exerted by this engine, on the printing material (01) acting as a tensile drive torque, wherein this measured value (MA) of the feed unit (02) controlling the control unit (06) or the feed unit (02) regulating control unit (07) is provided, the Rol is controlled or regulated in its run-up in response to this determined measured value (MA). On the other hand, a printing material web (01) is fed into the web press from an infeed unit (02) and / or a draw roller (03) arranged in the transport direction of the printing material web (01) according to a printing unit belonging to this web press, wherein the setting of the speed of the printing material web (01) in the web press retracting feed train (02) in response to a on the substrate web (01) acting tensile force, wherein the tensile force is exerted in the printing substrate by a drive torque of a motor of the draw roller, wherein the printing substrate (01) before reaching a minimum value for the force exerted by the motor of the tension roller (03), on the printing material (01) acting as a tensile force drive torque is drawn with a reduced speed compared to an otherwise permissible speed.
