Abstract (en)

[origin: US4703783A] The spread of particles which might otherwise be unevenly deposited upon a moving surface is equalized in accordance with a rated density distribution of the particle mass. The density distribution is determined across the particle mass and the particle distribution is varied so that the stream deposited upon the moving surface is uniform and in accord with a given density distribution.
