Abstract: This invention provides a distribution system suitable for coating articles placed in a given area with particulate material in a substantially uniform manner. The system comprises a plurality of arms which are provided with an inlet opening and a discharge opening. The arms are mounted for rotation about a central axis in conjunction with means for dividing and feeding a supply of particulate material from a source thereof into said inlet openings of the arms. The discharge opening is located on each of the arms in such manner so as to permit discharge of the particulate material from each arm over the given area, whereby when the arms rotate in conjunction with the dividing and feeding means, a supply of particulate material is divided and fed into the inlet openings of the arms and is discharged through the discharge opening. In this manner, a substantially uniform shower of the particulate material is provided over the given area.
