<p>The device for supplying under pressure a photographic coating station is comprised of a first reservoir intended to receive a given volume of photographic emulsion, said reservoir being connected to an air reservoir whose pressure is maintained constant by appropriate means, the volume of said air reservoir being much larger than the volume of the first reservoir so as to absorb substantially the relative variations of pressure related to the emulsion volume variations. Application to the coating of photographic products.</p> |
