Have you tried the same reel with another roll of film? That roll on the other reel? Could it be a problem of that particular roll of film on that particular reel?

A good solution for that (I've learned always to do it with Jobo, and never use the paterson's but we have them at school) is to clip the leading corners on the roll at about 45° (doesn't have to be anything like accurate, it's hard to do precision in the dark, or worse in a bag). Then, they ride up across the bars easily. It has saved lots of serious frustration.
The other frequent problem I encounter (among the students) is that they complain about the film going on the reel but slowing down gradually and becoming more and more difficult to turn the reel until it eventually stops altogether. This is because they didn't check to see if the reel was dry.
Peter Cooper (American industrialist/philanthropist and founder of Cooper Union) and his wife introduced the gelatin desert (aka Jello) as an adjunct to the glue business. Gelatin and glue have a lot in common. Sticky when wet.
