A method and an apparatus for the automatic filling of shipping bags with bulk materials with weighing accuracy. The pre-defined bulk material filling quantities are produced cyclically by controlling the discharge from a differential packer and weigher by determining the differential weight and are poured directly into the package via a flow filling sleeve. The pre-defined bulk material weight is directly packed as a dense stream on the shortest path via a flow filling sleeve. The majority of problems relating to weighing technology can be shifted to the area of the refilling of the differential weigher container with no disadvantageous results and no longer occur during the formation of the filling weight. The highest hourly outputs can be achieved particularly for packing carousels.
