The flap (2) of the bottom envelope (3) of a stack (1) is opened with a rotating opener claw (5, 6, 7 ). As soon as the flap is sufficiently open, it is seized by two rotating transport elements (8, 9) and pressed against two conveyor rollers (10, 11). The opener claws (5, 6, 7) and the conveyor elements (8, 9) are disposed on the same shaft (4), but are supported and driven independently of each other. The opener claws are only operated from a coupling (12) when a packing operation is to be carried out. The conveyor elements (8, 9) and the conveyor rollers (10, 11) run continuously. Two pairs of conveyor rollers (17, 18, 19, 20) convey the envelope towards a packing trap (13). As soon as the flap (2) of the envelope (3) is positioned below a holding down roller (21), the latter begins to descend. Simultaneously, the packing trap (13) begins to pivot towards the envelope. Whilst the envelope (3) is drawn onto the packing trap (13), the prepared contents (38) of the envelope is conveyed by transport fingers (34) into the packing trap (13) from the opposite side. Transport fingers (34) push the envelope (3) and contents (38) from the packing trap between conveyor belts (43, 44) and out of the enveloping unit.
