Abstract
Die Erfindung betrifft eine Vorrichtung zum Führen von Bogen in einer Bogenrotationsdruckmaschine, enthaltend einen zum Ausrichten der Bogen (4) ausgestatteten Anlegtisch (1), eine Anlegtrommel (2) und einen der Anlegtrommel (2) nachgeordneten Bogenführungszylinder (6), wobei die Bogen (4) innerhalb eines Übergabebereichs von der Anlegtrommel (2) an den Bogenführungszylinder (6) übergeben werden. Die Aufgabe der Erfindung besteht darin, insbesondere bei rotierenden Greifersystemen, mit Bogenleitelementen den Bogenüberhang so zu stützen, dass das Folgesystem den Bogen spannungsfrei übernehmen kann. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass unterhalb der Anlegtrommel (2) eine Blaseinrichtung (5) angeordnet ist, derart, dass durch die Blaseinrichtung (5) ein Blasluftstrom (51) gegen die Anlegtrommel (2) erzeugbar ist, der sich über die Breite der Anlegtrommel (2) erstreckt und bis in den Übergabebereich hinein reicht.The invention relates to a device for guiding sheets in a sheet-fed rotary printing machine, comprising a feed table (1) equipped for aligning the sheets (4), a feed drum (2) and a sheet guiding cylinder (6) arranged downstream of the feed drum (2). 4) are transferred within a transfer area of the feed drum (2) to the sheet guiding cylinder (6). The object of the invention is, in particular in rotating gripper systems, to support the sheet overhang with sheet guiding elements so that the sequential system can take over the sheet tension-free. According to the invention the object is achieved in that below the feed drum (2) a blowing device (5) is arranged such that by the blowing device (5) a Blasluftstrom (51) against the feed drum (2) can be generated, extending across the width extends the application drum (2) and extends into the transfer area.
Description
Die Erfindung betrifft eine Vorrichtung zum Führen von Bogen in einer Bogenrotationsdruckmaschine nach dem Oberbegriff des 1. Anspruchs.The invention relates to a device for guiding sheets in a sheet-fed rotary printing press according to the preamble of the first claim.

Nachteilig ist, dass die oben angeführten Leiteinrichtungen mit Düsen für einen abschmierfreien Bogentransport nahezu tangential zum bogenführenden System blasen. Das bewirkt eine von der Anlegtrommel weg wirkenden Kraft. Bei steigenden Maschinengeschwindigkeiten und dünnen, instabilen Materialien werden dann im Übergabebereich zwischen der Anlegtrommel und dem Bogenführungszylinder an den außen liegenden Greifern die Bogenecken abgespreizt. Diese herabhängenden Ecken werden beim Schließen der Greifer des Folgesystems gestaucht, was zu Bogenverspannungen oder Umstülpen der Bogenecken führen kann. The disadvantage is that the above-mentioned guide devices with nozzles for a smear-free sheet transport almost tangential blow to the sheet-guiding system. This causes a force acting away from the application drum. With increasing machine speeds and thin, unstable materials, the sheet corners are then spread in the transfer area between the feed drum and the sheet guiding cylinder on the outer grippers. These drooping corners are compressed when closing the gripper of the following system, which can lead to sheet tension or everting the corner of the sheet.
