Apparatus for singulating flat articles

An apparatus for singulating flat articles which are transorted on-edge as a stack on a controllably driven conveyor with a stack support to the take-away station where the frontmost article is taken away horizontally in a plane perpendicular to the feeding direction, having detectors projecting from the take-away reference plane at different heights for determining the position of the frontmost article at particular contact pressures which are connected to the drive controller of the conveyor, the conveyor and the stack support being driven in a separately controlled manner, wherein supporting elements can be individually moved horizontally in a plane perpendicular to the take-away reference plane using actuators and the detectors for measuring the position of the frontmost article, which are also provided for measuring the stack pressure, and that the drives of the actuators of the conveyor and of the stack support can be controlled as a function of the ascertained position of the frontmost article (1) in such a way that when the stack (12) is transported to the take-away station the frontmost object, supported by the supporting elements, is fed to the take-away station virtually parallel to the take-away reference plane with low stack pressure measured by the detectors at which it does not yet tip over or become deformed.
