It is especially applicable in the manufacture of tiles and pavement, obtaining these pieces upon compacting the granulate material (3) with a specific percentage of moisture, then followed by a drying, enameling, painting treatment, etc. and even kiln firing. The automatic control of compaction takes place upon distributing pressure sensors (1) in the mold itself of the press, built in the top (2) or bottom (3) punch, whereby making it possible to obtain data when pressing takes place. Therefore, the stability of the load is statistically controlled upon the sensors (1) communicating the force measured in differences of voltage, transforming these values into signals for a computer, by means of an amplifying system, processing these data to elaborate statistical values, etc., thus continuously informing about the pressing quality. The load correction is done by means of the intelligent feed slide that feeds the press that receives the corresponding orders with the value packages obtained by statistical evaluation. <IMAGE>
