Abstract
Um die Greifersysteme in ihrer Wirkung bereits in der Druckeinsatzzone und geringem Umschlingungswinkel des Bogens am Druckzylinder zu unterstützen, ist beginnend kurz vor dem Druckeinsatz eine Zone erhöhter Haftreibung (4) in der Ober fläche des Druckzylinders (1) über dessen Breite gesehen durchgehend angeordnet. Außerdem ist auf dem Gummituch (7) des Gummituchzylinders (6) mindestens in der Druckeinsatz zone eine gleitfähige Antihaft-Beschichtung aus einem Kunststoff mit geringem Reibungskoeffizienten vorgesehen. To see the effect of the gripper systems in the Pressure application zone and low wrap angle of the bow support on the impression cylinder is to begin shortly before Pressure use a zone of increased static friction (4) in the upper Surface of the printing cylinder (1) seen across its width arranged throughout. In addition, on the rubber blanket (7) the blanket cylinder (6) at least in the printing insert zone a lubricious non-stick coating from one Plastic with a low coefficient of friction is provided.
