Abstract

The invention relates to a press device for manufacturing tablets from a mixture of at least one component, comprising:

first means (7) for controlling a first punch, the first control means (7) comprising a compaction cam (9) for displacing the first punch (3) into a compaction position, said compaction cam (9) comprising a cam path on which said first punch (3) is capable of being displaced, the cam path comprising a planar portion (90) substantially perpendicular to the axis of the first punch (3), the planar portion (90) extending over an angular section comprised between 5° and 170° for maintaining the first punch (3) in a compaction die (2) at a fixed axial compaction position during a determined compaction maintaining time,second means (7) for controlling a second punch, the second control means (8) also comprising means for maintaining the second punch in said die at a fixed axial compaction position at least during said compaction maintaining time,so as to maintain, during said compaction-maintaining time, the confinement volume (V) at a constant volume corresponding to the compaction volume for forming the tablet.
