Post processing system and method

An apparatus for arranging flat mail items into a specifiable sequence of delivery points assigned to recipient addresses, comprising:

• at least one singling device having in each case a following read device for determining address information located on the mail items,
• a circulating temporary storage device serving at least two output conveyors and having a multiplicity of pouches configured to be opened downward in a controlled manner and permanently connected to said at least two output conveyors, with the mail items being transportable from each read device to in each case one pouch-loading station at which the mail items are loaded into in each case one empty pouch for sorting,
• said at least two output conveyors for accepting the mail items from the pouches of said circulating temporary storage device, with each output conveyor further transporting the mail items to a stacking device, with each of said at least two output conveyors having segments and moving relative to the circulating temporary storage device, with in each case a part of said at least two output conveyors being disposed beneath an overlapping area of the circulating temporary storage device, with a transporting speed and direction of said at least two output conveyors being matched to a transporting speed and direction of the circulating temporary storage device such that each segment of said at least two output conveyors passes by each pouch of the circulating temporary storage device at least once while moving along the overlapping area, and with the mail items being emptied onto respective ones of said at least two output conveyors from the pouches of the circulating temporary storage device in keeping with the read recipient addresses in such a way as to exit said at least two output conveyors in the stacking device in the specified sequence of the recipient addresses.
