The nozzles are arranged on the sheet guide surface in accordance with a first mode and a second mode, the nozzles arranged in accordance with a first of the modes outputting during operation a flow which counteracts a volume flow, from the blown air curtain, which is deflected downline with respect to the processing direction.
