Abstract
An apparatus for folding print sheets includes two folding rollers arranged on one side of a guide plane to define a folding gap. A compressed air device is arranged on the other side of the guide plane in a region of the folding gap. The compressed air device is connected to the compressed air source and to the control unit, and includes an exit opening for the compressed air that is focused onto the folding gap. Control elements can be activated by the control unit to change the time interval during which the at least one exit opening is admitted with compressed air, and/or the cross-sectional surface of the exit opening, and the pressure of the compressed air supplied to the exit opening may also be changed by a different control element, to adapt a compressed air blast to properties of the print sheet made available to the folding gap.
