How are flat spiral (pancake) coils wound? How does the machine
differ from a conventional computer controlled winding machine?

Isn't it just the degenerate case of 1 turn per layer?


No! More like one layer per turn-- but how do they get it to stay in
place?


But the ridiculous aspect ratio (height of turns : width of turns way
way bigger than one) will require some sort of bobbin wall.

I don't know much about "conventional computer controlled winding
machines" but have run hand-driven Morris coil winders.

A type of glue seems to be used; applied to the wire feeding into the coil.
