A part of two updates coming up
That's interesting, but it seems not all content is working, yet:
The illustration for the variable width slitter seems to be taken from an instruction text/book on the topic of film manufacturing, and not something specific to your project, correct?
The illustration on the coating machine still seems to be in the same conceptual stage it was earlier. It still piques my interest due to the unique approach towards coating the emulsion. I'd be interested to see if that actually works in practice to the performance required in this application.
The ambitions are very commendable in any case; I wish you the best of luck in realizing them.
