Abstract: The machine includes groups of bushes (1) of dimensions suitable for the superposed and aligned containment of a base cover (14), of a tablet (52) and of a lid cover (14).

Abstract: The bases and caps are aligned in two stages, with displacement by first pointed pushers (13-31) into corresponding calibrated horizontal channels (12-29) followed by displacement by second pushers (21-44) into corresponding calibrated vertical and descending channels (312-329). The second pusher (21) pushes the bases horizontally into the wider terminal part (20) of the descending channel, where the base is sucked by its sealed end and inserted into the corresponding supporting socket (1), with a vertical disposition and with the opening upwards. The second pusher (44), operating with the caps, acts on the intermediate parts of these with a point (144) which causes the caps to rotate with the opening downwards and transfers them with a vertical disposition into the wider terminal part (42) of the descending channel where the cap is held by a suction tube (46) which inserts it into the corresponding supporting socket (2).

Abstract: The apparatus makes use of a pair of rotating combs (11-14), the discs of the second comb being interposed between the discs of the first comb and positioned at the top between fixed guide plates (17). The discs of the first comb intercept the streams of closed capsules, from which any covers not provided with shells have already been removed. The capsules are inserted by their shells between the discs of the first comb and remain suspended on said discs by their covers (C1). Only capsule shells and any crushed capsules fall through the discs of the first comb. The capsules conveyed by the first rotating comb arrive on the discs of the second comb, generally with their covers at the front.
