1. A sheet handling device which comprises a sheet support element,
said element having a surface
containing suction holes communicating with at least one suction chamber, said suction chamber being connected to a suction device adapted to create a subatmospheric pressure in the suction chamber, wherein a flow obstructing material is arranged to obstruct the air flow through at least a subset of the suction holes which communicate with the suction chamber, said flow obstructing material being air-permeable but affecting an air flow resistance by defining obstructed air flow paths of difference lengths between different suction holes and the suction device.
