Abstract

A sheet brake for braking sheets made from a printing material contains circulating brake elements and at least one sheet support that is disposed between the brake elements and forms a blowing device. The sheet support contains a first nozzle array having air nozzles and a second nozzle array having air nozzles. The air nozzles of the first nozzle array are configured to produce blown air volumetric flows, which are smaller than blown air volumetric flows from the air nozzles of the second nozzle array.
