The current setup does something quite similar: It uses a tensioner to pull all three sheets (kinda like what the weight would be doing in your scenario). Unfortunately, using gravity is not an option due to the machine's stupid layout. So... instead of letting gravity do the work of aligning it, I have to find a way of manually lining everything upIs the tensioner based approach not working, then? I'd have thought that was your best bet. Trying to detect tiny alignment errors and then compensate for them (how?) feels like a much harder problem to solve.
Well, I think it WOULD work if I could get it aligned perfectly from the get-go. That's what I'm trying to detect the alignment; I want to use them to align the foil perfectly before I start the winding process. I don't think I can develop a compensating system.
