A device in which a set of capsules previously filled with a specific amount is positioned in a set of cavities arranged in plates, the plates assuming two positions, one for receiving the capsules in correspondence with a capsule-filling device, and the other for unloading these, the second operation being performed with the plates in an extended position in respect of the device frame, and the plates have two parts, an upper one which houses the capsules and a lower one which retains these. In the unloading position the lower plates align with the upper ones, thus allowing the capsules to drop through to arrange the gelatine capsules in blister packs.
