Abstract

The invention concerns a method for sorting mail items, said sorting being carried out base on characteristics located on the face of the mail items and by a sorting machine which sorts said explored and recognized characteristics. In order to ensure continuous final sorting in a sorting machine whereof the number of separation racks is less than the number of final directions, the input mail items are pre-sorted according to a pre-sorting plan. Simultaneously, final sorting operations are executed on the machine, the pre-sorted mail items being re-inserted in the sorting machine to be subjected therein to a final sorting.
