Abstract
Die Erfindung betrifft eine Bogenleit- und -bremseinrichtung in Auslagen von Druckmaschinen, bestehend aus kurzen mit Saugluft beaufschlagbaren Leitstaeben, welche laengs in Bogenfoerderrichtung, vor der aus mehreren Saugringen bestehenden Saugwalze, angeordnet sind. Aufgabe der Erfindung ist es, eine Bogenleit- und -bremseinrichtung in Auslagen von Druckmaschinen zu schaffen, die den Bogen quer zur Bogenaufrichtung strafft. Erfindungsgemaesz wird die Aufgabe dadurch geloest, indem den Bogenleitstaeben mehrere von Maschinenmitte beidseitig jeweils schraeg nach auszen unter dem Winkel verlaufende Laengsnuten zugeordnet sind, sowie die Saugringe unter der gleichen Komponente wie die Laengsnuten, von Maschinenmitte jeweils schraeg nach auszen unter dem Winkel , angeordnet sind. Fig. 3{Druckmaschine; Auslage; Bogenleitstab; Saugwalze; Saugring; Saugoeffnung; Saugschlitz}The invention relates to a sheet guiding and braking device in displays of printing presses, consisting of short acted upon with suction air Leitstaeben, which are arranged in Bogenfoerderrichtung, in front of the suction ring consisting of several suction rings. The object of the invention is to provide a sheet guiding and braking device in displays of printing machines, which tightens the sheet transversely to the bow erection. Erfindungsgemaesz the object is achieved by the Bogenleitstaeben a plurality of machine center on both sides each schraeg after auszen extending at the angle Laengsnuten are assigned, and the suction rings under the same component as the Laengsnuten, from the machine center each schraeg after auszen below the angle are arranged.

Bei Schön- und Widerdruck sind die Leitstäbe sowie die Saugringe der Saugwalzen in den druckfreien Bereichen des Bogens angeordnet und stützen bzw. bremsen so den Bogen ab.are formed. They protrude in the area of the guide plate directly in front of the suction roll next to each other over this and under-blow the bow. When perfecting the Leitstäbe and the suction rings of the suction rollers are arranged in the pressure-free areas of the sheet and support or brake so the bow.
