In the process and apparatus of the invention, a layer of powders (8) bearing patterns is laid on a rest surface of a belt conveyor (7), the conveyor belt is introduced between the bottom die (2) and the top die (3) above a cell (4) afforded in the bottom die (2), the layer of powders (8) is unloaded into the cell (4) by a swift withdrawal of the belt conveyor (7). 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 (8), by means of a translation which is parallel to the rest surface and which is very rapid. <IMAGE> |
