ABSTRACT:
The lower end 11 of a foil tube 6 rests in a vertical tubular bagging machine 1 without any mechanical tension from the remainder of the foil tube 6 on a scale 17. The scale 17 weighs the end 11 together with dosed product portion of a flowable product, which portion is fed into the end 11. The measured value of the scale is delivered to a volumetric dosing device 20. The dosing device 20 changes the mass of the dosed product portion dependent on measured values of the scale 17. The invention improves the packaging speed and the dosing exactness, in particular for dosed masses of less than 5 kg. of flowable product, for example powders.
