Method and apparatus for forming delivery devices for oral intake of an agent

A folding apparatus for folding a generally planar single or multi-layered sheet comprising a primary 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 at least a portion of the single or multi-layered sheet in the primary press and pressing the two opposite faces one versus the other a three dimensional device is formed with undulations that correspond in shape to that of said corrugated surfaces, the folding apparatus being configured for providing the three dimensional device with folds of increasingly smaller amplitudes upon extending away from an axis of the device so as to form a partially rounded cross section.

An apparatus for folding a discrete single or multi-layered sheet, comprising:

• (i) a primary press for folding said discrete sheet to provide a folded discrete sheet comprising a plurality of adjacent folded segments having respective fold lines extending along a first dimension of said discrete sheet;
• and
• (ii) a secondary press for pressing said folded segments of said folded discrete sheet towards one another along directions generally orthogonal to said first dimension to provide a compact configuration for the folded sheet.
