A method for the production monitoring with the manufacture of tablets in a rotary tabletting machine, with a row of upper and lower punches arranged in pairs, which cooperate with matrix bores, in which for each punch pair the maximum of the pressing force is measured, via a preselected number of readings (measuring row) an actual mean value is computed and compared to a nominal mean value and the supply of material to the individual matrix bores (filling degree) is changed when the deviation exceeds a predetermined measure, wherein before forming the mean value those pressing force readings of each measuring row, which significantly deviate with respect to other readings, are eliminated (freak value test).
