Abstract
An apparatus is shown for applying a homogeneous uniform layer of a powder to a surface of a part. The apparatus utilizes two belts which are made to track about two pairs of rollers in unison. A hopper containing the powder having an opening in the bottom is disposed so that the opening is closed off by one or both of the belts except for a slit aperture. The aperture is formed by a space between abutting ends of the two belt-roller assemblies. The apparatus is arranged so that as the belts track about the rollers the aperture traverses the opening in the hopper thereby permitting powder to pass through the aperture and fall to the part to be coated which is positioned directly below the opening.
