摘要： A method for decorating in thickness a ceramic slab, comprising the following steps: preparing, on a decoration surface (10), a first soft decorated layer (L1) of ceramic material endowed with a decoration (V); progressively transferring, by deposition, the soft decorated layer (L1) from the decoration surface (10) to a first deposition surface (50), situated at a lower height than the decoration surface (10), thus progressively forming on the first deposition surface (50) a second soft decorated layer (L2) which has a head (H) and a tail (T); progressively transferring, by deposition, the second soft decorated layer (L2) from the first deposition surface (50) to a second deposition surface (83), situated at a lower height than the first deposition surface (50), starting from the tail (T) of the second soft decorated layer (L2), thus progressively forming on the second deposition surface (83) a third soft decorated layer (L3).

摘要： A machine (1) for depositing ceramic powders comprises a supply device (2) and a distributor device (3) of the ceramic powders. The supply device (2) is configured to convey the ceramic powders receiving them from a process situated upstream of the machine. The distributor (3) is movable along a processing direction (X) which extends in a support plane and is configured to receive the ceramic powders from the supply device (2) depositing at least one layer thereof on the support plane during an advancement and/or reverse movement thereof along the processing direction (X). A system for making ceramic tiles or slabs is also claimed, comprising (i) the machine (1) for depositing ceramic powders, (ii) a conveyor belt (11) defining the support plane and (iii) a pressing device arranged along the support plane downstream of the machine (1) and configured to press at least one layer of ceramic powders deposited by the machine (1).
