ABSTRACT:
A tablet press machine (1) includes a fixed casing (2) which houses a compression assembly (3) comprising a power-driven rotor (4) that rotates about an axis (5), the rotor including a matrix disc (6) and another two discs (7, 8) on both sides of it, mounting two sets of reciprocating punches (9, 10) opposite and aligned with each other in pairs. The matrix disc (6) has a plurality of through matrixes (11) where the reciprocating punches (9, 10) forming each pair are mounted in such a way as to delimit between them an empty space (12) of variably size designed to contain a dosed quantity of powder to be compressed. Two sets of cams (13, 14) are associated with the compression assembly (3) and, as the rotor (4) rotates, impart on the punches (9, 10) a driving motion which moves them cyclically towards and away from each other in such a way as to compress the powder contained in the matrix (11) in the matrix disc (6). The casing (2) comprises, inside it, sealed separating means (15; 18, 19, 21, 22) desigend to delimit separate spaces (16, 17, 20) for housing the compression assembly (3) and the sets of cams (13; 14) in order to prevent the powdered product from contaminating the cams.
