Abstract: A dispensing device for decorating ceramic tiles with granular or powdered materials that includes a main body and a dispensing channel arranged in the main body and provided with a longitudinal axis. The channel has an inlet and an outlet opening along with a suction means, provided to retain a part of granular or powdered material inside the dispensing channel to form an accumulation that obstructs the dispensing channel and prevents the flow of material. A suction opening is arranged in communication with the dispensing channel and with the suction means and has a filter, interposed between the suction opening and the dispensing channel. A ventilation portion, associated with the main body and connected to the inlet opening of the dispensing device has an outer surface that communicates with the environment as a determined pressure.

Abstract: A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.

Abstract: A dispensing device for dispensing a granular material, comprising a dispensing channel (20) provided with an inlet opening (21) and an outlet opening (22).
