Abstract
Description
Ein ungleichmäßiges Aufliegen des Bedruckstoffes auf dem Druckzylinder bzw. unteren Gummituchzylinder ist dabei nicht auszuschließen, insbesodere im Bereich der Hinterkante des Bogenmaterials.
Dabei weist die Bogenführungseinrichtung wenigstens eine pneumatisch beaufschlagbare Kammer mit auf den Bedruckstoff gerichteten Öffnungen für den Blasluftaustritt auf. In einer Weiterbildung weist die Bogenführungseinrichtung mehrere Kammern auf, die durch Abschottungen getrennt sind und separat mit Pneumatiksystemen für die Blasluftversorgung gekoppelt sind. Alternativ ist auch die Ausbildung mit einem Pneumatiksystem mit nur einer Blasluftversorgung ausführbar, wobei die Blasluftversorgung bis an die dem Druckspalt benachbarte Kammer reicht und die Blasluft durch Öffnungen in den Abschottungen in die weiteren Kammern zurückströmt.
Zwischen der Unterseite (Führungsfläche) der Bogenführungseinrichtung und der Mantelfläche des Bogenführungszylinders ist ein Auslaufspalt gebildet, der ausgehend vom Druckspalt in Förderrichtung einen sich erweiternden Spalt aufweist.

- Fig. 4
- eine Bogenführungseinrichtung mit Blas-Sog-Düsen
In einer Weiterbildung, ist die Bogenglätteinrichtung 17 von den verschließbaren Mitteln freilegbar, das Pneumatiksystem 18 ist umgeschaltet auf Blasluftversorgung, so daß aus den Bohrungen, Schlitzen oder der Nut des Glättspaltes Blasluft in Richtung Bogenführungszylinder, Druckzylinder 10 ausströmt. Die Bogenglätteinrichtung 17 ist somit eine Blasvorrichtung. Die kinetische Energie der Blasluftströmung aus dem Bereich der Blasvorrichtung (umgeschaltete Bogenglätteinrichtung 17) wirkt als Druckenergie P3 auf den Bedruckstoff, wobei bevorzugt gilt P1 > P2 > P3 > P0.
Die Bogenführungseinrichtung 9 mit Blas-Sog-Düsen 25 weist in Förderrichtung 8 wiederum die Führungsfläche 22 auf, welche in einfacher Form als nahe an den Druckspalt 12 reichendes Leitblech 20 ausgebildet ist. Darüber hinaus ist die Bogenführungeinrichtung 9 ebenso mit pneumatisch beaufschlagbaren Kammern 13, 14, 15 ausführbar. Dabei ragt die Kammer 13 am weitesten in Richtung Druckspalt 12 und die Kammer 15 ist am weitesten vom Druckspalt 12 entfernt. Die Kammer 15 nimmt das Leitungssystem 23 für die Druckluftzuführung auf oder ist selbst als Leitungsystem für die Druckluftzuführung ausgebildet. In dieser Ausbildung ist die Kammer 15 mit jeder Blas-Sog-Düse 25 direkt in Funktionsverbindung. Die Kammern 13, 14 weisen, wie bereits beschrieben, die in die Führungsfläche 22 integrierten Öffnungen 16 für den Blasluftaustritt auf.
Ist die Bogenführungseinrichtung 9 mit Blas-Sog-Düsen 25 ausgestattet, so wird der Bedruckstoff durch den Unterdruck gegen die Führungsfläche 22 sowie die Unterseite der Einsatzelemente 24 gezogen und entgegen der Förderrichtung 8 gestreckt. Bei Ausbildung mit dem Leitblech 20 wird der Bedruckstoff daran bis kurz vor den Druckspalt 12 geführt. Bei Ausbildung mit den Kammern 13, 14 wird der Bedruckstoff mittels der aus den Öffnungen 16 austretenden Blasluft und deren Druckenergien wiederum auf den Druckzylinder 10 gedrückt.
