ABSTRACT:
A powder applicator for applying powder in a stream to side seams of container bodies. The powder is directed towards an associated nozzle entrained in a carrier gas. However, as the gas entrained powder approaches the nozzle, it passes through a centrifuge section of the supply tube wherein the powder is separated from the gas and is directed against a radially outer portion of a return bend which extends through an arc on the order of 180.degree.. As a result, the powder is directed to the orifice of the nozzle as a continuous dense stream with the gas being in a layered relation with respect to the powder.
