Abstract
An apparatus for metering powdered filling material has a filling material container whose bottom is provided with bores which cooperate with tamping plungers and transfer plungers. Underneath the bottom is a stop ring which functions as a counter support for the tamping plungers. To prevent powder losses from the bottom the filling material container is axially movable in such a way that it can be pressed against the stop ring during the downward motion of the tamping plungers. This is achieved by means of hold-down elements which can be moved synchronously with the tamping plungers.
