US Patent 9340363 Apparatus and method for transferring particulate material

An apparatus for transferring, at high speed and in a very effective and accurate manner, particulate material from a feeder into reservoirs of a moving endless surface, e.g. a drum, by use of a pressure means, e.g. a specific three-dimensional plate, for applying pressure onto said particulate material present between said plate and said moving endless surface, and then transferring the particulate material with said moving endless surface with reservoirs to a substrate; the apparatus and method being particularly useful for the production of absorbent structures for absorbent articles.
