Abstract
An apparatus adapted for use in the processing of a material traveling in a material direction, such as a photosensitive material. The apparatus directs a first fluid stream and a second fluid stream respectively across the first and second width portions of the material. The first and second fluid streams do not flow substantially cocurrently with nor countercurrently to the material direction.
