Abstract

A method of manufacturing very thin metal sheets having a large number of small openings, characterized in that on a model metal plate, whose drawing has the shape of the grid, a soluble substance is deposited from steam that covers the metallic model plate With a thin layer, then metal is applied by vacuum deposition, in such a way that the intermediate layer is completely covered and that the openings are not covered, after which the carrier assembly, the intermediate layer and the protective layer are submerged in a liquid, in order to eliminate, by dissolution, the intermediate layer completely or at least in a part such that the metallic protective layer is easily separated from the carrier, in which, for the intermediate layer, a substance is used that does not react chemically at all with the metals of the model plate and the grid and that it is soluble in a liquid that does not attack at all or that does not attack in essence these such.
