<p>The device has collecting channel (4) extending along longitudinal axis transverse to direction of gravity (3), below reservoir (2) for powder (1). The reservoir is opened by opening (6) into collecting channel opens, to form unrestricted passageway for powder from reservoir to collecting channel. The collecting channel has channel bottom (7) with respect to direction of gravity below opening. A pressurizing unit applies a pulsating pressure to collecting channel so that discharge opening (8) of collecting channel, arranged laterally to opening partially discharges amount of powder. An independent claim is included for method for operating metering device.</p> |
