摘要： A sheet-guiding apparatus for a turning device in a rotary printing machine guides a sheet being printed to prevent smearing. The turning device includes a turning drum and at least one sheet-guiding cylinder. The turning drum and the sheet-guiding cylinder define a sheet transfer region and a sheet transfer path. The sheet-guiding apparatus comprises an air blower means, at least one blower/suction device, and a lower sheet-guiding device. The air blower means, which is arranged upstream of the sheet transfer region, includes a first set of air outlet openings for directing compressed air toward the sheet-guiding cylinder and at least a second air outlet opening for directing compressed air into the transfer region. The blower/suction device, which is disposed within the sheet-bearing surface of the turning drum, communicates with a plurality of openings disposed in the sheet-bearing surface and is coupled to a pneumatic device. The lower sheet-guiding device is disposed below the sheet transfer path and is switchable between providing compressed air and providing air suction. The air blower means, blower/suction device, and the lower sheet-guiding device cooperate to provide a combination of air blow and suction for guiding the sheet in the sheet transfer process.
