I'm interested in learning about the early stages of the coating/converting/manufacturing process for early film production (say before 1920 or so). I want to learn about what type of equipment was used to sensitize the first generation of flexible roll films for cinema and still use and maybe also papers before the production became automated on an enormous industrial scale.

Can anyone recommend resources (books, patents, etc) or share some knowledge about how this was done?

  • One specific question I have is when did roll-to-roll slot-die coating become the standard, and what was used before it?
  • How did R&D-scale coating differ from production-scale in the early days?
  • What techniques and methods might be the most simple and relevant for a tinkerer in the modern age to make an attempt at replicating?
 
Wall, Photographic Emulsions is another good reference.

For a tinkerer, you can start with Denise Ross’ Light Farm website, specifically the section on film coating.
 
Sometimes I post on this topic. But in general interest was so little and posts were deleted that I feel not much urge to do so.
 
The author did not approach me in those years. And I have been belittled here for my input on such historic matters, that I refrain from doing so.
