ABSTRACT:
A method for forming plate-like ceramic articles, comprising at least one step for deposition by pouring of at least one layer of a ceramic mixture that comprises an aqueous vehicle on a substantially absorbent transfer surface adapted to draw the aqueous vehicle, at least one step for drying so as to obtain a continuous material strand, and a cutting step for cutting the strand into a plurality of ceramic articles. An apparatus for performing the method comprising a framework for supporting an absorbent transfer surface, at least one unit for depositing at least one mixture layer onto the surface, at least one drying unit for at least partial drying of the mixture layer to obtain a continuous strand of plastic ceramic material, and a cutting unit.
