A system for producing an agent delivery device for oral intake comprising: (i) an assembly apparatus adapted to assemble one or more layers comprising one or more materials and an agent or an agent-releasing formulation to form an integrated device; (ii) a folding apparatus adapted to fold the integrated device into a folded integrated device; (iii) an enclosing apparatus adapted to at least partially enclose the folded integrated device within an enclosure to form a device in a form suitable for oral delivery, - wherein said assembly apparatus is adapted to assemble said one or more layers comprising said one or more materials and said agent or said agent-releasing formulation into a generally planar assembly to form said integrated device; - wherein said folding apparatus is adapted to fold the integrated device into the folded integrated device defining a first axis, such that the folded integrated device has folds of increasingly smaller amplitudes upon extending away from the first axis to form a partially rounded cross-section: and - wherein said folding apparatus comprises a press with two opposite faces, each face having a corrugated surface with ridges of one corrugated surface being essentially opposite to troughs of the other corrugated surface and essentially fitting one into the other; whereby upon placing the integrated device in the press and pressing the two opposite faces one versus the other an undulated, three dimensional device is formed with undulations that correspond in shape to that of said corrugated surfaces.
