(54) An apparatus for distributing batched quantities of powder or granular materials on surfaces


(57) The apparatus of the invention distributes batched quantities of granular or powder material on surfaces, and comprises a hopper (1) having a bottom (2) which affords at least one plurality of openings (3) for releasing the powder, each of the openings (3) being associated to an obturator. The obturator comprises a stopper (4) having a U-shaped transversal section which acts tangentially in proximity of a portion of surface of the bottom (2) affording the opening (3). The stopper (4) inserts, by means of upwardly-projecting ribs (40) at ends thereof, into hollow seatings (30) afforded in the bottom (2), and thus closes and frontally seals against a sealing surface (5) arranged laterally to the opening (3). Upper edges of the ribs (40) are located higher than the openings (3).
