Jobo reel identification

[eddie]

While sifting through the attic, I came across a few of these reels, which were included when I bought a Jobo processor, years ago. I've never used them, and am not sure how they work. Was there a special loader required? Thanks for any info.

Here's another photo. They're strange reels (to me, anyway). You can't "walk-on" the film. They have little teeth, instead of channels, for the film edge. And, there's no gap to start the loading.

What is the width where the film would go?

[eddie]

They're adjustable for 35 & 120.

There's one of those on ebay right now and they are calling it a "35mm reel for 4x5 size (2501 and similar) tanks"

I still don't see how you get the film on it though! And it even looks like there are some nubs about halfway along the arms that would make it even harder (unless the idea is to put two rolls on there?)

This is a 2500 series reel designed for extremely high quality side to side uniformity and long lengths of film. It can hold a 70+ exposure roll of 35mm. The reels needed a special loader for each size. They were discontinued quite some time ago.

They still produced the sheet film version after stopping the roll film version from the 2500 series. They also produced a large, redesigned version of the above reel that does not need a special loader and looks like a more conventional reel.

I've the sheet film reels for the 2500 drums and I've also got some of these reels as I intented to use them for 220 and 72 exposure 35 mm film (HP-5 Autowinder film) and I could NEVER get the film onto the reels... I have the loader for the sheet film reels, but I never could figure out how to get it to work with these reels and roll film.

With the roll film loader it is not too difficult. You do have to practice. I have a 35mm and a 120 loader here somewhere. There are photos of them in the old Jobo catalogs if you can get one. I have about 6 or so of the reels but I retired them a few years ago in favor of the more conventional design.

I have the 3073 reel, is that what you mean by the more conventional version of this thing? That one supposedly handles quite a bit more than 70 exposures (I hope so - I bought it to do the film from my 100-exposure Canon back!)

I think there has to be a loader. Durst used to have spirals with a guide/loader for 35mm, but this is not one of them. I wonder if it is 35mm/70mm, not 35mm/120, and what the spiral length is? Bulk film, maybe.
