Abstract

See full text

An apparatus and method for optional cross-folding of successively following, sequentially printed sheets on a first transport segment. A compressed air device comprises a first control element that is connected to a control unit for triggering or suppressing a compressed air blast from at least one exit opening in the compressed air device. A printed sheet is diverted into a second transport segment for the folding operation or a third transport segment for bypassing the folding operation. The latter empties downstream of folding rolls into the second transport segment at a joint segment point, at which a fourth transport segment adjoins in downstream direction. The third transport segment is longer than the second transport segment or can be operated at a lower speed than the second transport segment such that a first sequence of printed sheets successively following on the first transport segment is identical to a second sequence of the successively following printed sheets located on the fourth transport segment.
