How White Bread is Made (in a Factory) Video
I was pleasantly surprised: the process isn't as Frankensteinian as I expected it to be. (I still won't eat it, however).
It's on Netflix streaming: http://movies.netflix.com/WiPlayer?movieid=70209929&trkid=3325854&t=How+It%27s+Made%3A+Ssn+1%3A+Aluminum+Foil... 
Season 1 Episode 1 of "How It's Made".
The bread part of the video starts at 15 minutes 50 seconds into it.
