To provide a packaging machine which speedily and precisely packs a powdery body or a granular body, especially a powdery body of a high relative bulk density in a bag.

This packaging machine is equipped with: a first packaging section A and a second packaging section B. In this case, the first packaging section A applies a rough filling to a packaging bag (a) which is supported by a grip pair under a suspension, by an auger device 35 having a deaerating function. The second packaging section B applies sealing on the bag mouth b after filling a regular content amount by applying a compensating filling by an auger device 50 to the packaging bag (a) which has been received from the first packaging section A. The compensation amount to the rough filling amount is calculated from measurement data for every plurality of times by a metering means 40, and the compensation value (inclination pulse number) to the compensation amount is fed back to the control section of the auger device 35, and the rough filling from the next time and on is applied by the weight changed by the compensation, and this motion is repeatedly performed.
