Sorry for asking, but I cannot seem to find any information on this and it is purely for the curiosity. 
Simple question: How does the typical film-lab develop machines work?
I mean, in terms of getting the film (135) off the cassette and into the system/onto some spool for some dunk and dip in various chemicals, then wash and then dry?
Even worse, how the heck do they process 120 film, with the baking paper on? I really cannot see a machine spooling out 120 film and cutting the tape of the end against the backing paper without experiencing major jams and potential scratches on the film.
Would be interesting to know how these machines actually work, even if film is somehow fed manually into these things, how do they do that (and 120, how do they avoid exposing the film to light?).
I really tried googling this, but I keep getting "good offers" for developing film in film-labs
