Abstract

A sorting machine with a standard operator work space containing a compact and ergonomic assembly of a hopper (5) for a horizontal stack of envelopes (3) between a control panel (6) and an extraction head (9), and a set of pigeonholes (11) for receiving a large enough number of sorted envelopes to prepare a postman's round. The pigeonholes are arranged above the hopper and supplied by a conveyor moving along a path in such a way that the orientation of the envelopes remains the same as they are delivered from the hopper (5) to the pigeonholes.
