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.

L'invention concerne un procédé de fabrication de comprimés lenticulaires par calandrage d'une matière fondue, procédé selon lequel on utilise des cylindres de formage présentant des évidements sous forme de segments ellipsoïdaux. Ce procédé permet d'obtenir des comprimés faciles à ébarber et caractérisés en ce que le reste de comprimé à meuler est minime en cas de décalage entre la moitié supérieure et la moitié inférieure du comprimé.
