weighing process i e the net scale 1 weighs the product being filled portion by portion u2014 e g in amounts of 25 kg u2014 and then releases the thus weighed portions via the tube hopper arrangement 2 and the neck 6 into the container 7 this operation provides the benefit of a particularly high productivity in comparison to the gross system in order to avoid hereby the detrimental effect of overfilling the container 7 the product stream or at least part thereof is transferred into an intermediate chamber 3 which is arranged in the tube arrangement and or hopper arrangement 2 this intermediate chamber 3 receives depending on the air content of the product a portion of the product released by the net scale u2014 preferably about 20 50 in particular about u2153 of the product the remaining product flows past the intermediate chamber 3 which does not cover the entire cross section of the tube hopper arrangement 2 and is directly introduced into the container 7 the ratio of the split of the product between the intermediate chamber 3 and the portion directly introduced into the container is hereby selected such that no overfilling of the bag can be experienced fig1 a fig2 a projecting into the container 7 is e g a compaction device 8 from its open topped side or a differently arranged compaction device 9 which is constructed to so compact the product introduced into the container 7 as to liberate a portion of the absorbed air during the now commencing compaction.
