Abstract
The present invention relates to a coating hopper for applying one or more layers of photographic liquid onto a web of paper or film support. The device incorporates a liquid passage system with a metering slot of defined width which leads to an expansion section having an increasing width as liquid moves away from the metering slot. The expansion section is connected to a discharge slot having a defined width greater than that of the metering slot which delivers photographic liquid to a location on the coating device where a layer of that liquid is formed.
