Interesting - I don't think I've seen a belt like that (at least not where the 
"non-rung" parts are open). I've seen ones with 'guide rails' in flatbed 
scanners and the like, of course, but not with actual gaps between the belt's 
teeth (which I think is what's implied here)

I wonder if anyone's ever managed to make rubber widgets in the home workshop? 
I don't mean things like repairing tape drive wheels using heatshrink tubing, 
but actually making the bits from scratch using some form of solution / heat / 
drying / vulcanising process. Probably a horrible trial-and-error experience, 
and maybe impossible, but I've not come across anyone who's even attempted it...

(I did try, at age 9 or so, making my own toy car tires by using a clay mould 
and attempting to melt down other old toy car tires. The result, as I recall, 
was a big mess)
