<p>The present invention is directed to a vibratory powder feeding and metering apparatus that achieves the above-mentioned requirements. Generally, the apparatus of the present invention includes a housing (12) defining a powder reservoir (18), a powder storage hopper (14) having an outlet (15) disposed to deliver powdered resin to the reservoir (18), a powder distribution block (16) having one or more generally vertical fill tubes (44), a plurality of discharge ports (26) extending from the reservoir (18) to the fill tubes (44) in the distribution block (16), and a vibration device (49) to which the housing is mounted. Typically, the fill tubes are in communication with individual spray nozzles for transmission of the powdered resin. The housing also carries an adjustable barrier (34) which serves as a dam to control or meter the flow of powdered resin into the discharge ports. <IMAGE></p> |
