Les trous d'aspiration (301) maintiennent chacun un comprimé (9) par aspiration sur une surface latérale de ce dernier. La surface de guidage (332) vient en contact avec la surface avant ou la surface arrière des comprimés (9). Lorsqu'un moteur relié au tambour d'aspiration (30) est entraîné, la pluralité de trous d'aspiration (301) et les comprimés (9) qui sont aspirés et maintenus sur les trous d'aspiration (301) se déplacent en rotation autour d'un axe de rotation (O). Grâce à cette configuration, il est possible de transporter une pluralité de comprimés (9) dans une direction de transport de façon à ce qu'ils soient alignés et espacés les uns des autres d'un intervalle prédéterminé, sans nécessiter de mécanismes complexes utilisés dans des dispositifs classiques.
