Beschreibung
Zusammenfassung:	The invention relates to the production of granulates by using a tabletting machine comprising at least one top punch and one bottom punch which co-operate with a die formed with a bore, the top punch being displaceable into the bore from outside to compress powder accommodated in the bore and the bottom punch displaceable in the bore being displaced within the bore for ejecting the powder compressed into a tablet, the tabletting machine additionally comprising a powder feed unit which introduces the powder into the bore when the top punch is in its raised position. According to the invention, a perforated plug in the bore of the die in conjunction with a granulate stripping, transporting and collecting system arranged beneath the lower end face of the perforated plug is used instead of the displaceable bottom punch for producing granulates.
