Abstract

A process for coating substrates of whatever form with a layer of powdered substance of constant thickness distributed regularly over at least part of the substrate, by removing the quantity of powder required for the coating from a feed hopper and distributing it on a conveyor of structure suited to the grain size and density required at temperatures below the coating temperatures, so as to obtain uniform distribution. The process avoids difficulties of even distribution due to electrostatic charges mutual adhesion of the particles due to heat and other factors.
