Process and device for filling packaging containers, in particular tubular bags or similar packages, with doses having a predetermined weight of a fluid, powdery or finely granulated filling material, with the filling material being gravimetrically introduced into the packaging containers such that the predetermined amount of filling material to be introduced into the packaging container is fed by means of a speed-controlled metering screw at intervals, gravimetrically regulated, from a first filling material supply, and a measured amount of the filling material more or less equivalent to the amount dispensed is subsequently fed from a second filling material supply to the first filling material supply within a time corresponding to the stop period of the packing machine.
