Abstract

An apparatus for processing sheet material includes a transport device for transporting single sheets of the sheet material. The transport device includes a diverting device for diverting the transport direction of the single sheets having one or more opposite first and second diverting elements between which the sheets are transported through for diversion. One of the diverting elements has a roughened surface with depressions of at least 1 mm. The apparatus further includes a smoothing device arranged so as to pull apart the sheet material in a direction perpendicular to the transport direction immediately before diversion in the diverting device.
