On my 3.5F, the roller is virtually level with the film guides.
Logically, the roller would be level to within a couple of thou' to
prevent the film bending away from the guides as it rolls tightly onto
the spool. Higher than that and it would lift the film off the guides
and lower than that, the film could be come scratched or kinked as it
moves over the guides. There must be a tolerence listed somewhere (in a
repair manual?). Are these rollers adjustable by shims etc or are
different diameter rollers used to suit the height of the film guides?
The lens would be adjusted for focus on each camera so the exact
dimension of the film guide to front face of casting would not
necessarily be that critical. I guess parallelism would be more so.

Subject: [rollei_list] Rolleiflex 2.8C Film Frame
A Rolleiflex technical querry for a change. : )
I've been thinking a bit about the problem (discussed many times
already) of over exposure in a line along the top of the frame.
Example here: http://www.flickr.com/photos/elroustom/2422405163/
I was looking at the two vertical rails on either side of the frame,
that the film is pressed against, and noting how much higher they are
than the two horizontal limits of the frame. I can understand the need
to recess these to avoid scratching the film as it winds past, but I
wonder if they are too low? Does anyone have a 2.8C and a later model
that does not exhibit this "Bug"? And can you compare the difference in
height between the vertical rails and the horizontal ends around the
film frame?
Illustration of question here:
