Abstract
A method and system are provided for adjusting a discharge width of a powder feeder. The system includes a supply hopper that is spaced from the powder feeder. The powder feeder includes a receiving opening and a discharge opening and at least one adjustable wall. Preferably, two adjustable walls are provided. Movement of the two adjustable walls provides variations in the width of the discharge opening and therefore facilitates use of the powder feeder on target volumes or target areas having different widths. A rotatable auger brush is in communication with the supply hopper for causing powder withdrawn from the supply hopper to be transported to the powder feeder and disposed uniformly across the receiving opening of the powder feeder. The brush is immersed within the powder and extends across the receiving opening of the powder feeder, and maintains a filled level powder feeder. The powder feeder is particularly well-suited for use in a coating apparatus, as well as a dual-side coating apparatus.
