Abstract

In a device for singulating vertically positioned flat mailings from a stack of mail, at least two discharge rockers are disposed on top of one another, wherein the discharge rockers are adjacent to revolving second discharge belts that are arranged in a fixed manner along the path of travel. A supporting element in relation to which the stack of mail is aligned ends at a defined distance from the undeflected discharge rockers. A flexible, elongated retaining element is arranged in a resiliently pressed manner from the end of the supporting element to the beginning of the second discharge belts located downstream of the discharge rockers and further on to the discharge rockers and to further discharge belts of successive singulating stages. The distance of the supporting element from the leading end of the second discharge belts relative to the direction of travel is greater than the maximum permissible length of a mailing.
