Filling station for filling an envelope (126, 128, 130, 132), the filling station being configured to receive a filling material (122, 134a, 134b) and an envelope (126, 128, 130, 132), the filling station comprising: a filling area comprising at least one stationary filling aid, the filling aid including plurality of fingers which may be at least partly pulled up onto the envelope so that the filling aid is arranged in a throat opening of the envelope; an envelope feeding plane configured to receive an envelope and to arrange the envelope at least partly at a position outside the filling area; and a transport device configured to move an envelope, which is arranged in the envelope feeding plane, into the filling area; the envelope feeding plane being configured to receive a subsequent envelope during a movement of the preceding envelope from the envelope feeding plane into the filling area and/or during filling of the preceding envelope, and to keep same outside the filling area, the transport device being configured to move the envelope arranged in the envelope feeding plane counter to the material transport direction (R G) in the direction of the filling aid to at least partly pull the envelope up onto the filling aid, characterized in that the envelope feeding plane is configured to receive the subsequent envelope below a position where an envelope is filled, so that during operation, the preceding envelope and the subsequent envelope are located one above the other simultaneously, the preceding envelope within the filling area and the subsequent envelope within the envelope feeding plane, the preceding envelope and the subsequent envelope being arranged in an at least partially overlapping manner when viewed from above, and the transport device is configured to move the subsequent envelope out of the envelope feeding plane and into the filling area once filling of the preceding envelope has been completed and before discharge of the filled envelope from the filling station has been completed. a filling area comprising at least one stationary filling aid, the filling aid including plurality of fingers which may be at least partly pulled up onto the envelope so that the filling aid is arranged in a throat opening of the envelope; an envelope feeding plane configured to receive an envelope and to arrange the envelope at least partly at a position outside the filling area; and a transport device configured to move an envelope, which is arranged in the envelope feeding plane, into the filling area; the envelope feeding plane being configured to receive a subsequent envelope during a movement of the preceding envelope from the envelope feeding plane into the filling area and/or during filling of the preceding envelope, and to keep same outside the filling area, the transport device being configured to move the envelope arranged in the envelope feeding plane counter to the material transport direction (R G) in the direction of the filling aid to at least partly pull the envelope up onto the filling aid, characterized in that the envelope feeding plane is configured to receive the subsequent envelope below a position where an envelope is filled, so that during operation, the preceding envelope and the subsequent envelope are located one above the other simultaneously, the preceding envelope within the filling area and the subsequent envelope within the envelope feeding plane, the preceding envelope and the subsequent envelope being arranged in an at least partially overlapping manner when viewed from above, and the transport device is configured to move the subsequent envelope out of the envelope feeding plane and into the filling area once filling of the preceding envelope has been completed and before discharge of the filled envelope from the filling station has been completed.
