ABSTRACT:
Device for guiding a sheet having a leading edge which follows an imaginary conducting surface along a sheet-transport direction perpendicular to the leading edge, the sheet-guiding device being formed with a sheet-guiding surface spaced from the imaginary conducting surface, and having equipment for generating a plurality of air jets for applying an air flow to the sheet between a surface of the sheet and the sheet-guiding surface, the generating equipment being formed of respective flow channels for the air jets disposed at an angle to and merging with the sheet-guiding surface, includes an integral guide plate having a surface constituting a predominant part of the sheet-guiding surface, the integral guide plate being formed with perforations, the air-jet generating equipment being formed of blast-air nozzles having blast-air nozzle end faces constituting a remaining part of the sheet-guiding surface complementing the predominant part of the sheet-guiding surface to form the entire sheet-guiding surface, the blast-air nozzles fitting into the respective perforations formed in the guide plate so that the blast-air nozzle end faces are flush with the surface of the guide plate, the blast-air nozzles, respectively, having the respective flow channels formed thereon, and being formed with a nozzle bore passing therethrough and communicating with the respective flow channel.
