In one aspect the invention provides a tablet alignment apparatus for the alignment of tablets (20) having a longitudinal axis, the apparatus comprising a conveyor disc (23) and a ram (33), the conveyor disc (23) having at least one generally radial slot (25') open to the circumference of the disc (23) and dimensioned to receive a tablet (20) therein and to enable the ram (33) to reciprocate therein, the radial slot (25') being defined by one planar radial side (41'), a base (42') and a convex radial side (45'), the arrangement being such as to enable the longitudinal axis of a tablet (20) to be aligned radially between the base (42') of the slot (25') and the ram (33). In another aspect the invention provides a tablet alignment apparatus comprising an index table (50) and an index member (52) for alignment of a tablet (20) having two parallel flat surfaces interconnected by two convex surfaces, the operative surface of the table (50) having two stepped portions (56, 58) which successively raise the height of the table (50) in the direction of intended relative travel of a tablet (20) over the table (50), the minimum operative separation between the index member (52) and the table (50) and the respective heights of the steps (56, 58) being such as to ensure that regardless of whether the initial orientation the tablet (20) is with a flat surface or a convex surface in contact with the table (50), the tablet (20) is positioned on top of the final step (58) with one of its convex surfaces in contact therewith. |
