    Abstract: The invention concerns a method of producing lenticular tablets by melt calendering, using form cylinders provided with ellipsoid-segment recesses. The proposed method produces tablets which are easy to trim and in which any misalignement between the top and bottom halves of the tablet is such that only a small residue needs to be ground off.
