Abstract (en)
A method of forming substantially flat ceramic products (P) comprises preparing a ceramic paste (IP), extruding the ceramic paste (IP) through an extrusion die (2) and over a cutter (3) to obtain a substantially continuous multiple ribbon (4) of paste with first and second ribbons (4a, 4b) of the multiple ribbon (4) not being joined together but having a separation plane that is substantially parallel to the faces of the multiple ribbon (4), and severing the first and second ribbons (4a, 4b) transversely to provide the products (P), the extruding being performed substantially horizontally. The individual products (P) so obtained are squashed to reduce their thicknesses and to increase their plan areas and are then cut to size around their peripheries.
