Abstract

Die Erfindung betrifft eine Bogenleiteinrichtung in der Bogenanlage von Druckmaschinen mit einer Schwinganlage.The invention relates to a sheet guiding device in the sheet feeder of printing machines with a vibrating system.

Aufgabe der Erfindung ist die Schaffung einer Bogenleiteinrichtung,mit der der abziehende Bogen ohne Beschädigungen zum Zylinder gefördert wird und sich ohne zu flattern an die Oberfläche des Zylinders anlegt.The object of the invention is to provide a sheet guide device with which the pulling Bow is conveyed to the cylinder without damage and without fluttering to the Surface of the cylinder.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in Umlaufrichtung (19) des Zylinders (3) vor einer Übergabeposition (20), in der die Übergabe eines von der Schwinganlage (2) geförderten abziehenden Bogens (10) an den Zylinder (3) erfolgt, eine sich über die gesamte Breite des Zylinders (3) erstreckende pneumatische Bogenleiteinrichtung (21) vorgesehen ist zum Ableiten einer durch einen Mantel (16) des Zylinders (3) sowie einer dem Mantel (16) zugewandten Seite des abziehenden Bogens (10) initiierten Schleppströmung.

Figure 00000001
According to the invention, the object is achieved in that in the direction of rotation (19) of the cylinder (3) before a transfer position (20) in which the transferring of a pulling sheet (10) conveyed by the vibration system (2) to the cylinder (3) takes place, A pneumatic sheet guiding device (21), which extends over the entire width of the cylinder (3), is provided for discharging a drag flow initiated by a jacket (16) of the cylinder (3) and a side of the withdrawing sheet (10) facing the jacket (16) ,
