I'm investigating, they seem to roll fine, I'm wondering if this cord should not be having the film under the first roller...I read it was to be loaded this way and now am finding conflicting info...I'm downloading a manual to be sure.
I've used a Rolleicord III intermittently since about 1979 and can confirm that it should *NOT* take the film under the first roller. That's almost certainly your problem, IMHO. The film goes over both rollers. (Most Rolleiflexen, and maybe later 'cord models, have a "feeler" roller that the film goes under---I didn't know this when I first got my Rolleiflex, and I couldn't figure out why it would just advance and advance forever...)
