Abstract
A removable stacker for automatic mail sorting system comprises a stacking area, a mobile wall adapted to hold documents on edge and to move against the action of a return device as the stacker is filled and an articulated flap adapted to assume a first position in which it is retracted and a second position in which it cooperates with the mobile wall to grip the documents during manipulation of the removable stacker. A system is provided for maintaining the flap in its second position against the action of the weight of the stacked documents.
