Abstract
A method for forming ceramic tiles, including those of large dimensions, comprising the following stages: loading the powder to be pressed into the mould cavity; exerting an initial pressure on the entire surface of the powder present in the mould cavity; releasing the initial pressure; exerting the compacting pressure on the entire surface of the powder contained in the mould cavity; increasing the pressure on a first portion of the surface of the powder contained in the mould cavity up to a value permitted by the press capacity; releasing the pressure on said first portion of the surface of the powder contained in the mould cavity and increasing the compacting pressure on a second portion of the surface of the powder contained in the mould cavity; alternating the exertion of pressure on said first portion and on said second portion; and interrupting the exertion of pressure.
