ABSTRACT:
A process for quality control in tablet production by pressing by means of influencing the pressing force, the weight, the hardness, and the height of the tablets by means of a control mechanism. The task of the invention is to develop a process of the type according to this concept, according to which all necessary control mechanisms for maintaining a constant tablet weight, tablet height, and tablet hardness operate in such a way that a rapid control of deviations is assured, and according to which, the limiting values can be optimized automatically, is hereby resolved in that the control system is divided into several influential and essentially parallel running control circuits for the simultaneous control of the pressing force as well as the tablet parameters of weight, height, and hardness.
