Yes, you're right. Each tank has a "rack" which has a set of spools on both top and bottom. The film enters over one spool, then multiple passes up and down in a helical wind pattern and exits from the other side of the rack. You spool the emulsion side out, so it virtually never has to contact anything.

If you didn't have these multiple loops, the machine would need a very slow speed, comparable to a mini-lab processor.
