(54) Method, charging device and press for the production of tiles with striping or veining in the mass


(57) A method for the production of tiles with veining in the mass comprises the steps of charging powder into a vertical well to be pressed to form the tile mass and powder for formation of the veining in the mass, opening the well at the bottom to dump powder along a horizontal box translating with relative movement below it, and sending the box to a press for pressing of the powder therein. A press for pressing tiles in accordance with the method is equipped with a charging device (14) comprising a charging box (18) running between a rest position outside the press and a dumping position within the press. The device also comprises a vertical accumulation well (19) into which is fed powder for producing the tile mass and powder for achievement of veining in the mass and which on command dumps from its bottom into the box arranged beneath it during a relative translation movement between the box and the accumulation well.
