ABSTRACT:
A method and apparatus for continuously liquefying a gelled photographic material for coating on a substrate is disclosed. The material is advanced throughout the liquefaction apparatus and on to the substrate coating system as a substantially undisrupted mass. The technique is particularly useful for liquefying small amounts of material at a time, because system hold-up volume and waste is minimized.
