Abstract

The present invention relates to a method for automated, continuous singling of loose sheet material, by the steps of feeding a stack of loose sheet material to be singled located on a first feeding element from a deposit position to a position in which the uppermost sheet of the stack can be grasped by the singling unit, sheet-by-sheet singling of the fed stack by the singling unit, the stack being fed by the feeding element such that the particular uppermost sheet of the stack can be grasped by the singling unit, feeding a further stack of loose sheet material to be fed located on a second feeding element from the deposit position to a position in which the uppermost sheet of the stack to be fed is located below the first feeding element, and uniting the stack to be singled and the fed stack by drawing the first feeding element out of the feeding path.
