The device has a feed hopper (1) to displace stacked postal items (3) e.g. letters, on a front edge at an extracting head (5). The head has a motorized drive actuated to separate a current item and stopped at each extraction of the current item and the items are straightened in the hopper in response to detection of signals (S) provided by sensors (20-22) e.g. reflective photocells, placed in the head. The signals indicate presentation of the current item with respect to the head, where driving of the head is actuated, if the signals indicate the current items`s presentation. |
