<p>A mail accumulating device having a number of stream forming units (27), each of which has a pair of powered belts (35, 44) superimposed at a point of contact (Z) defining the input of the unit, and a sensor (63) for detecting the passage of a mail item into the unit, and for generating a signal for activating the belts, moving the mail items retained on the belts from the input (Z) to the output (68) of the unit in discrete steps (S1), and forming a group (Ibs) of overlapping mail items with the leading edges separated by a substantially constant distance. The device also includes a number of conveyor belt devices (73, 86, 93), each of which has an input (71) communicating with the output (68) of a respective stream forming unit (27), receives the group (Ibs) of mail items at the input (71), and feeds the group of mail items (Ibs) to an output (102) of the conveyor belt device (73, 86, 93) to define an accumulating unit. <IMAGE> <IMAGE></p> |
