Abstract (en)
[origin: DE4315680A1] The invention relates to a method for quality assurance in the production of tablets using presses, which works by affecting the pressing force, the weight, the hardness and the height of the tablets by means of regulators. The object of the invention to develop a method of the generic type in accordance with which all the necessary regulating mechanisms to keep tablet weight, height and hardness constant operate in such a way that rapid elimination of deviations ensured and in accordance with which limit values can also be automatically optimised, is achieved by virtue of the fact that the regulating system is set up in such a way that it is composed of a plurality of interacting and essentially parallel regulating circuits for simultaneous regulation of the pressing force and the tablet parameters weight, height and hardness.
