ABSTRACT:
A method and device for sorting flat and indexed articles are disclosed, the method involving two passes. In the first pass, articles having a destination common to a very large member of articles are sorted and distributed to N/2 receptacles (10), the receptacles being fewer in number than the total number (N) of possible destinations for the articles, while the other articles are put aside in a buffer receptacle (12). In the second pass, a control circuit (7) assigns new destinations to the sorting receptacles, placing a marker (16) after each pack of articles contained in the receptacles, and the articles initially set aside (21) are resorted to the new destinations. The invention is particularly applicable to mail sorting.
