An improved device for forming ceramic products, including slabs, tiles and the like, by powder pressing

摘要

The improved device of the invention comprises a lower element (2) for supporting powder (20) to be pressed and an upper element (4) between which two elements (2 and 4) the powder (20) will be pressed. The invention is characterised by the fact that it comprises means for surrounding and sealingly isolating at least a part of the powder (20) from an outside environment when the two elements (2 and 4) are reciprocally neared. Air is aspirated from the isolated part of the powder, creating a depressed environment. <IMAGE>
