Abstract
An atomizing bell or cup for use in a rotary atomizing apparatus includes a generally frusto-conical-shaped wall having an outer surface and an inner flow surface which terminates at an annular atomizing lip. A plurality of radially outwardly extending fins or ribs are formed on the inner flow surface of the cup upstream from the atomizing lip which are circumferentially spaced from one another to provide flow paths therebetween for coating material flowing along the interior surface of the cup such that the coating material is divided into a number of individual streams before reaching the atomizing lip. These streams are emitted from between adjacent ribs a short distance upstream from the atomizing lip which allows centrifugal force to at least partially flatten the streams forming ribbon-shaped streams, which, when flung outwardly from the atomizing lip, form completely atomized coating particles which are substantially free of air bubbles.
