Device for the dispensing of a powdered product on a ceramic manufactured article

Abstract

Device (1) for dispensing a powder (P) on a ceramic article (M) comprising: a hopper (3) for a powder to be released on the ceramic article to be decorated; a plurality of nozzles (4), each defining a relevant containment chamber (5) for containing powder, communicating with the hopper (3) and provided with a relevant output gap (6); releasing means (12) controllable to selectively dispense the powder through the relevant output gaps (6) of the nozzles (4); distribution means (14) of the powder on the ceramic article to be decorated, comprising a rotatable roller (15) arranged below the output gaps (6) and at least one supporting element (19) of the roller (15), adapted to interact with the roller itself along its longitudinal development. Preferably, the supporting element (19) is of the contactless type, in particular of the magnetic type, comprising first magnetic means (20) adapted to define a first magnetic field (20a) and the roller (15) comprises second magnetic means (21) adapted to define a second magnetic field (21a), wherein the polarities of the magnetic means (20, 21) are arranged in such a manner that the magnetic fields (20a, 21a) repel each other to counteract the axial inflection of the roller (15).
