1. A sealing device for sealing packages, the sealing device comprising:
a sealing station with a plurality of receptacles for packages;
a transfer belt arranged upstream of the sealing station for transferring packages to the sealing station;
a transport belt arranged upstream of the transfer belt for transporting and transferring packages to the transfer belt; and
a feeding device for feeding packages to the transport belt,
wherein the transport belt and the transfer belt can be driven independently of one another,
wherein the sealing device comprises at least one sensor, which is adapted to determine a distance between successively transported packages in the feeding device, and a control unit, wherein the control unit is adapted to determine a speed profile of the transport belt and a speed profile of the transfer belt based on a distance of successively transported packages measured by the sensor, and to control the transport belt and the transfer belt as a function of the speed profile so that the distance of successive packages during a transfer to the sealing station corresponds to the distance of adjacent receptacles for packages.
