Abstract (en)

[origin: WO2010037580A2] In a sheet conveying device comprising at least one conveying arrangement with a porous conveyor belt that can be moved in a circulating manner, at least one vacuum source and at least one air line whose one end is connected to the vacuum source and whose other end abuts against the porous conveyor belt, a simple and automatic control of the suction pressure for different sheets is achieved by at least one constant pressure controller in the air line in order to essentially maintain constant a pressure differential between the interior space of the air line and its environment.
