ABSTRACT:
Apparatus for singularizing stacked paper sheets has a rotary sheet withdrawing unit with a set of equidistant rotatably mounted transfer elements having suction cups which attract successive lowermost sheets of a stack in a magazine adjacent a first portion of the endless path of orbital movement of the transfer elements. The transfer elements deliver the sheets into a second portion of the endless path where the sheets are transferred toward an endless belt conveyor having a reach which advances in the direction of advancement of transfer elements in the second portion of the endless path and at a speed which exceeds the speed of orbital movement of the transfer elements. The leaders of the sheets are caused to abut stops on the endless belt conveyor.
