Abstract
Powder is fed from a container into a continuous annular groove on a rotating metering plate. A doctor member ensures that the powder is correctly filled into the groove. The powder is then sucked out of the groove after the plate has rotated through a certain angle by a suction device which has a projection extending into the groove.
