Understanding Neutron Radiography Reading V-Kodak Part 2 of 3

Although the primary function of the transport system is to move the film
through the processor in a precisely controlled time, the system performs two
other functions of importance to the rapid production of high-quality
radiographs. First, the rollers produce vigorous uniform agitation of the
solutions at the surfaces of the film, contributing significantly to the uniformity
of processing. Second, the top wet rollers in the racks and the rollers in the
crossover assemblies effectively remove the solutions from the surfaces of
the film, reducing the amount of solution carried over from one tank to the
next and thus prolonging the life of the fixer and increasing the efficiency of
washing. Most of the wash water clinging to the surface of the film is removed
by the squeegee rollers, making it possible to dry the processed film uniformly
and rapidly, without blemishes.
