The invention relates to a weighing device for a packaging machine. Empty capsules that are still closed are removed from a capsule holder, weighed on a gravimetric scale, placed back into an empty capsule holder, and then taken apart. The device makes it possible to remove empty capsules and replace them at full machine speed, without a loss of any consequence in output. It is possible to use a gravimetric measurement method to carry out a tare weighing of the capsules. An additional weighing device for filled capsules is integrated into a capsule transport device to determine the net weight based on the tare weight and the weight of the full capsules. Such a combination of a gravimetric tare weighing and a gross weighing to statistically determine the net weight is particularly well-suited to an intermediate capsule filling device.
