Abstract: Method and device for separating letters by transporting a pile of non-separated and unordered letters by a conveyor band in a continuous flow of essentially non-superposed letters which are largely distributed on said conveyor band. At least one retention plate which is fixed to an axis of rotation in a radial direction with respect thereto rotates around the axis of rotation, which is transversally arranged with respect to the transporting direction of the conveyor band, horizontally and above said conveyor band in such a way that the retention plate arranged under the axis of rotation has a velocity component oriented in the opposite direction to the direction of travel of the conveyor band.

Abstract: A method for processing mail, wherein a plurality of mailing items inserted into insertion places are collected and subsequently transported in a container to postal centers where they are sorted in sorting devices according to postal categories. The invention is characterized in that the mail is placed in transport containers which are transported to unloading areas in postal centers. When the transport container is filled and/or during the transportation of the container to the postal centers, random partial pre-sorting of mail takes place according to postal categories so that, when, the mail is removed from the containers at the unloading areas, it is in the form of piles formed by the predetermined pre-sorting method and sorted according to the postal categories, whereupon it is guided to subsequent processing stations according to said postal categories.
