Definitions
- the invention relates to a method and a device for Sheet guidance in a printing machine according to the generic terms of independent claims.
- the At least one sheet guiding device is in one embodiment with a large-area blowing device with a high volume flow coupled as a pneumatic system and has openings for Place the printing material on the outer surface of the sheet guide cylinder using blowing air.
- the facility forms a wedge-shaped with the sheet guide cylinder Inlet gap, one in the conveying direction in the inlet gap continuous pressure increase up to the pressure zone.
- the Device can consist of several chambers with openings for the Blow air leakage exist.
- Another sheet guiding device is from DE 197 53 089 A1 for a printing press with a forme cylinder and a Bow guide cylinder known.
- Such a sheet guide device has several chambers for the blown air, the increasing in the conveying direction of the substrate before the printing zone and printing levels acting on the substrate exhibit.
- This facility forms with the associated Sheet guiding cylinder has an inlet gap in the conveying direction is arranged tapering to the pressure zone.
- the invention is based on the object, a method and a device of the type mentioned in a printing press to create that avoid the disadvantages mentioned, which in particular a more even guidance of the sheet material without touching the sheet guiding device on the Bow guide cylinder allowed and an improved infeed ensure the sheet material in a printing zone.
- the task is characterized by the training features of claim 1 and 2 solved. Further training results from the dependent Claims.
- the invention assumes, among other things, that in the conveying direction of the sheet material in the area in front of the printing zone - in contrast to the working principle with continuous pressure increase - a differentiated pressure distribution, in particular over three pressure distribution areas, of the sheet material is realized.

- this third pressure distribution area is at least opposite the second pressure distribution area higher pressure level (higher dynamic pressure) of the blast air jets on that from the sheet guiding cylinder transported sheet material applied.
- the pressure level of the blown air in the third pressure distribution range is preferred, at least in the immediate vicinity of the Pressure zone, higher than the pressure level of the blowing air in the first Pressure distribution area.
- the device for sheet guidance is in the conveying direction of the Sheet material in the gusset-shaped space in front of a printing zone arranged in such a way that between a guide surface (underside the sheet guiding device) and the outer surface of the sheet guiding cylinder an inlet gap is formed which in Direction of conveyance to the pressure zone a tapered course having.
- Another advantage is that according to the invention in the pressure on position (Printing / painting operation) as well as in print from position (Gap in the pressure zone with an inactive printing / Coating unit) of the blanket cylinder or forme cylinder Bow guide cylinder the method applicable as well as the Device can be acted upon pneumatically.
- Another training course is in addition to that in the funding direction Device for sheet guidance arranged in front of the printing zone another, for example identical device for Sheet guide arranged in mirror image after the printing zone and serves to guide the sheet material when leaving the Pressure zone.
- This acts on the sheet material Pressure level preferably in different pressure distribution areas divided, the one immediately downstream of the pressure zone Pressure distribution area the higher pressure level of the Blown air jets.
- the device is arranged after the pressure zone can also be implemented in another training for guiding the bow.

Abstract
Description
Dazu ist in Förderrichtung des Bogenmaterials im zwickelförmigen Raum vor einer aus einem Gummituchzylinder oder einem Formzylinder und einem Bogenführungszylinder gebildeten Druckzone achsparallel zum Bogenführungszylinder eine mit einem Pneumatiksystem gekoppelte Einrichtung zur Bogenführung angeordnet, bei der die kinetische Energie der Blasluftströmung in einen auf das Bogenmaterial wirkenden Staudruck umgewandelt wird. Dabei ist diese Einrichtung durch wenigstens eine Kammer mit Öffnungen für den Blasluftaustritt zum Auflegen des Bogenmaterials auf die zugeordnete Mantelfläche gebildet
- Fig. 1
- eine Bogenrotationsdruckmaschine,
- Fig. 2
- eine Bogenführungseinrichtung im Bereich der Druckzone,
- Fig. 3
- die Druckverteilung vor einer Druckzone,
- Fig. 4
- die Abwicklung einer Leitfläche mit Öffnungen einer der Druckzone vorgeordneten Einrichtung zur Bogenführung.
Damit ist eine mögliche gegenseitige Beeinflussung vermeidbar bzw. spürbar reduzierbar.
Im Polbereich sind die Öffnungen 17 ebenso bevorzugt durch achsparallele Blasschlitze, alternativ durch Blasbohrungen, gebildet. Diese Blasschlitze bzw. Blasöffnungen sind bevorzugt in der Relativlage seitenversetzt parallel im Polbereich anordbar.
Die Öffnungen 19 im konkav ausgebildeten Krümmungsteil der Leitfläche 21 sind bevorzugt als Blasbohrungen ausgebildet.
Um ein Unterblasen der Hinterkante des Bogenmaterials zu vermeiden, ist bevorzugt wenigstens die dem Pol mit Öffnungen 17 benachbarte Reihe von Öffnungen 18 im konvex gekrümmten Teil der Leitfläche 21 senkrecht (Oberflächen normale) auf die Mantelfläche des Bogenführungszylinders 5 gerichtet.
Beispielsweise sind konvergierende Blasluftströmungen im Druckverteilungsbereich 16 auf den Bogenführungszylinder 5 bzw. das Bogenmaterial gerichtet, um ein erhöhtes Druckniveau zu erzielen. Hingegen sind divergierende Blasluftströmungen im Druckverteilungsbereich 22 auf den Bogenführungszylinder 5 bzw. das Bogenmaterial gerichtet, um (gegenüber dem Druckverteilungsbereich 16) ein vermindertes Druckniveau zu erzielen. Dies ist mit einer einzigen gemeinsamen Luftkammer, welche mit einem Pneumatiksystem in Funktionsverbindung ist, realisierbar. Mit der Ausnutzung konvergierender bzw. divergierender Blasluftströmungen ist beispielsweise eine Einrichtung 7 mit mehreren, pneumatisch unterschiedlich beaufschlagbaren Luftkammern für die einzelnen Druckverteilungsbereiche 16, 22, 23 vermeidbar.
Dabei weist bei der nachgeordneten Einrichtung 9 der der Druckzone 15 unmittelbar nachfolgende Druckverteilungsbereich das höhere Druckniveau der Blasluftstrahlen auf.
