Method for decorating in thickness a ceramic slab

A device for the decoration in thickness of a ceramic slab, comprising:

• a decorator device, provided to prepare a first soft decorated layer of ceramic material endowed with a decoration on
• a decoration surface, situated below the decorator device;
• a first deposition surface, situated at a lower height than the decoration surface;
• a second deposition surface, situated at a lower height than the first deposition surface;
• a first motor means, configured to provide a relative motion, directed along a longitudinal direction, between the decoration surface and the first deposition surface said first motor means being provided to slide the first deposition surface along the longitudinal direction, while the decoration surface, being slidable along its path around rollers, is static on the whole along the longitudinal direction, said first motor means being provided to transfer the soft decorated layer from the decoration surface to the first deposition surface, progressively forming on the first deposition surface a second soft decorated layer which has a head and a tail, the head being formed by the material that is deposited first on the first deposition surface, the tail being formed by the material that is deposited last on the first deposition surface;
• a second motor means, configured to provide a second relative motion, directed along the longitudinal direction, between the first deposition surface and the second deposition surface;
• wherein the first motor means and the second motor means can be activated independently of each other;
• characterized in that:
• said first motor means are configured to reverse the motion of the first deposition surface, such that a second decorated layer is transferred to the second deposition surface, which moves in the same direction as the first deposition surface, the tail of the second layer being the first part to be transferred and deposited on the second deposition surface.
