Abstract

In an apparatus for singling sheet material, multiple picks are avoided by a retaining device ensuring that sheet material entrained with the sheet to be singled is retained not only on one side but also on the other side of the sheet to be singled. While the first retaining device is located opposite a singling gap of the singling device and is continually effective, the second retaining device acts before, or in, the singling gap from the other side of the singling gap and is only activated after the sheet to be singled is reliably grasped by the singling device, and deactivated when it has left the singling gap.
