The decoration assembly (7; 7a, 7b) comprises a first module (8) for dispensing adhesive fluid, of the type provided with heads with dispensing nozzles, adapted to dispense at least a first layer of adhesive fluid on the surface of the item (P) to be decorated according to a specific decorative pattern or motif, and at least one supplying device (9) of granular material (M), arranged adjacent to said first module (8) and downstream of the first module (8) with respect to the feed orientation (V), adapted to dispense at least one layer of granular material (M) on the portion of the surface of the item (P) in which the first layer of adhesive fluid is present. The decoration assembly (7; 7a, 7b) comprises a second module (10) for dispensing adhesive fluid, of the type provided with heads with dispensing nozzles, arranged adjacent to the supplying device (9) and downstream of the same supplying device (9) with respect to said feed orientation (V), adapted to dispense a second layer of adhesive fluid on the previously deposited layer of granular material (M); the second layer of adhesive fluid is superimposed on the decorative pattern or motif created by the first layer of adhesive fluid.
