A device for transforming a continuous and controlled flow of absorbent material in granules into an intermittent flow for providing the material to a receiving member movable along a direction X, including a feed manifold, an outlet and a main body, placed between the feed manifold and the outlet, configured to cause the absorbent material to flow along a direction (Y′-Y′) coinciding with the respective axes of symmetry of the feed manifold, the outlet nozzle and the main body; wherein within the main body a movable element is housed, capable of moving alternately between a first and a second working position, such that when the movable element is in the first position, it forms a first accumulation chamber of the material, and a first discharge duct of the material, and when the movable element is in the second position, it forms a second accumulation chamber and a second discharge duct.
