ABSTRACT:
A powder dispensing assembly (10) comprising; support structure (20), a dispensing platform (26) supported by the support structure (20) for receiving powder and having a distal lip (28) over which particles of powder move to define a falling curtain of powder particles. A supply platform (30) is supported by the support structure (20) for receiving powder and supplying the powder to the dispensing platform (26). A flow control device (34) establishes a flow path of the powder from the supply platform (30) to the dispensing platform (26). A drive device (36) vibrates the dispensing platform (26) to move particles thereover and over the lip (28) and to move the supply platform (30) in unison with the dispensing platform (26) to move powder from the supply platform (30) and through the flow control device (34) to the dispensing platform (26). A shelf (54) is disposed below the lip (28) for receiving the powder from the lip (28 ). The shelf (54) is stationary and extends downwardly to a distal edge (56) at an inclined angle sufficient for the powder to flow thereover under the force of gravity and over the edge (56).
