ABSTRACT:
An apparatus for producing tablets from particulate material having a weight between preselected weight limits wherein a metered quantity of particulate material is compressed in a die to form a tablet having a preset thickness. The final compression pressure is measured and compared to preselected pressure limits. The metered quantity is adjusted if the measured pressure is outside the pressure limits. At selected time intervals, the tablets are weighed and if the tablet weight is outside the preselected weight limits, the pressure limits and/or the preset thickness is adjusted to bring the tablet weight within the weight limits.
