Essentially the device comprises a net wound about a roller (1) fixed by ends thereof to flanges (7) and rings (8) connected to the external machine for support and rotation thereof. The roller (1) is impregnated with liquid glaze (6) by the doctors (4,5) and nozzles (12) located inside the body blow a fluid at the net, transferring droplets of glaze (6) entrapped in the net onto the surface of the tile (3) to be decorated.
