The assembly to give an automatic correction to the density of ceramic tile blanks controls the volume of the granulate fed into the press mold. The push filling unit has a scraping bar (16) at the leading end, of a material with elastic distortion, set at various height levels in sections by pneumatic or hydraulic pressure cylinders (2) with pistons (3). The assembly to give an automatic correction to the density of ceramic tile blanks controls the volume of the granulate fed into the press mold. The push filling unit has a scraping bar (16) at the leading end, of a material with elastic distortion, set at various height levels in sections by pneumatic or hydraulic pressure cylinders (2) with pistons (3). The setting cylinders are operated by electrically controlled valves (10-13) through signals according to a control program during the scraping action, to give the required density distribution in the ceramic blank. The setting cylinders are mounted at a rigid carrier (1), at intervals of 20-60 mm.
