A method of charging a package with dosed bulk material, includes the steps of filling the package in a pre-filling station to an extent less than a desired final weight; weighing the partially filled package; determining the difference between actual and desired weight of the package; advancing the partially filled package to an after-filling station; and filling the package in the after-filling station with additional bulk material having a weight corresponding to the determined weight difference. Metering of the additional bulk material and readying the additional bulk material for delivery into the package are started before the package assumes a charging position in the after-filling station.

In a method of charging packages with dosed bulk material, including the step of filling each package in a pre-filling station to an extent less than a desired final weight; weighing each partially filled package; determining the difference between actual and desired weight of each package; and advancing each partially filled package to an after-filling station; the improvement comprising the following consecutive steps: (a) metering an additional bulk material with a dosing screw into a dosing chamber situated in said after-filling station; the additional bulk material having a weight-corresponding to the determined weight difference; said metering step being of constant duration for each package and bieng started before the respective package assumes a charging position in said after-filling station; said metering step comprising the step of regulating the rpm of said dosing screw as a function of the weight difference; and (b) filling the respective partially filled package in the after-filling station with the metered additonal bulk material by releasing the metered additonal bulk material from said dosing chamber.
