  • Process and apparatus for loading dies for forming ceramic tiles
    Patent number: 6669008
    Abstract: In an apparatus, a layer of powders bearing patterns is laid on a rest surface of a belt conveyor, the conveyor belt is introduced between the bottom die and the top die above a cell afforded in the bottom die, the layer of powders is unloaded into the cell by a swift withdrawal of the belt conveyor. The withdrawal of the unloading end of the conveyor belt is carried out with no relative dragging between the rest surface and the bottom of the layer of powders, by a movement which is parallel to the rest surface and which is very rapid.
