    Abstract: Centrifugal arranging and feeding apparatus in which the articles to be arranged are introduced toward the center of a rotating disk. Outward movement of the articles is limited by a flexible retaining ring which is lifted in a first region of rotation to permit articles to pass to the periphery of the disk. In a second region, the articles pass from the periphery of the disk onto an elevator ring which lifts the articles to a delivery ring. A guide retains the articles on the delivery ring until they reach a discharge region where they are delivered from the ring in a generally tangential direction.
