The extrusion device is intended for the formation of ceramic alveolar structures, and is formed from a block, in one face of which there are made openings for the admission of the ceramic paste, which communicate through the block with a network of open intersecting slots in the opposite face of this block. The block is formed by assembling small bars 10 of rectangular cross-section, attached by their vertical faces 17, 18, the admission openings 30 being made by notches 20 made in at least one of said vertical faces 17, 18, starting from each upper face 15 of the small bars. Application in the production of inexpensive extrusion blocks with slots for the exit of ceramic material of small thickness. |
