Method of merging non-machine-sortable postal articles with machine-sorted mail pieces

A method of merging postal articles for delivery together with mailpieces sorted in a machine into relevant delivery rounds, the method comprising the following steps:

• entering data into the sorting machine that is representative of delivery addresses of the postal articles to be merged;
• in the sorting machine, simulating an ordered sequence of mailpieces for delivery on the relevant delivery round, and, on the basis of said data, determining in the simulated sequence respective locations for said postal articles to be merged;
• sorting said mailpieces into sorting outlets of the machine for delivery on relevant delivery rounds, and, while each mailpiece is being machine-sorted, detecting whether said mailpiece is a mailpiece adjacent to a postal article to be merged in said simulated sequence;
• and
• responding to each said detection by inserting a separator into the sorting machine so as to direct said separator automatically towards the sorting outlet of the machine that corresponds to the delivery address of said postal article;
• at the end of the machine sorting of the mailpieces and of the separators, putting the postal articles in place of the separators to merge said postal articles with the mailpieces for delivery on the relevant delivery round;
• and
• activating each separator remotely and visually identifying the separator.
