Guide device for freshly printed sheet - has front edge of sheet spreading theoretical guide surface along running direction vertical to front edge

摘要

Following the guide surface and spaced from it is a sheet guide surface in the form of a surface of a guide plate arrangement. Over the sheet guide surface, and issuing in it, are distributed blown air apertures. The blown air apertures (9.1,10.1) are formed on blown air nozzles (9,10) of a first nozzle configuration and of at least a second nozzle configuration. The blown air apertures of the nozzles of the second nozzle configuration are represented by gaps formed in the sheet guide surface (6) established by channel sections impressed into the guide plate arrangement (7), and extender between theoretical pairs of concentric circles (13,14) equally distributed over 360 deg.
