Abstract

Improvements in presses for the manufacture of cement products - such as pressed tiles and others - of the type that comprise a structure provided with several molds and cyclically moveable by firing to successively carry each of the molds of the different operating stations, each mold comprising a porous bottom with which a cavity capable of being placed under vacuum is combined to extract the liquid phase from the material contained in the mold, when this mold is at least in a suction station, characterized by the fact of presenting each mold a mouth (28) for communication with the outside, connected to the cavity that must be put under negative pressure, and if a suction group (38) is provided in the suction station or in each of them (D), coupling to the mentioned mouth of the mold stopped in the same station produces the negative pressure in the cavity of the same.
