ABSTRACT:
A processing apparatus comprises at least one wet processing station followed by a dryer in which wet sheet material comes into contact with heated drying air. Sheet material is fed over a static support member which supports the sheet material during drying. A drying unit is positioned opposite to and extending across the support member in a transverse direction, thereby to define a drying space between the support member and the drying unit. Drying air is fed to the drying unit to pass out through a drying air exit into the drying space. The support member includes a plurality of openings to allow drying air to pass therethrough, to ensure that the air flow is substantially the same whether a sheet of photographic material is positioned on the support member or not, while minimising the generation of turbulence.
