Abstract
The present invention relates to an apparatus for singling flat material to be conveyed having a suction device, with openings in the suction device defining an area within which the suction device grasps the material to be singled.Known singling devices have in particular the disadvantage that operation of the suction device produces a high noise level which is felt to be very unpleasant.The present invention provides a shifted arrangement of the suction openings which leads at least to partial elimination of the noise during shifted activation of the suction openings.
