The present invention relates to a transfer line for the transfer of identical filled two-piece capsules between two successive processing stations comprising a and on unloading area, a plurality of identical transfer units each comprising a plurality of cavities each adapted to receive a capsule at the loading area and to let such capsule being unloaded at the unloading area, said plurality of cavities of each transfer unit being designed so as to receive in a first relative configuration the groups of filled two-piece capsules when located at a loading position in the loading area and so as to discharge these groups when located at an unloading position in the unloading area, a conveyor device adapted to temporarily and individually support the transfer units so as to transfer them from the loading position to the unloading position and vice-versa, while keeping them substantially in a same orientation in the loading and unloading positions, and at least from the loading position to the unloading position.
