Abstract
The device includes a side wall (13), which leaves open a slot (15) of a variable width relative to a support (11). The flaps of letter envelopes are inserted into the slot (15) angled at 90 degrees, where the letter envelopes rest in a stack on the support (11) and are maintained on their side by the side wall (13). Three sensors (36, 38, 39) serve to provide signals for a motor control of the position of the side wall. The side wall can be manually moved against the force of a spring (26).
