How can I model a twisted belt that runs on offset pulleys?

Hi all.  I am working on a motion transfer assembly.  I am trying to accurately model a timing belt that runs on offset pulleys (yes, I know this is an atypical application).  I need accurate bends and twists in order to model appropriate intermediate rollers where the belt changes direction.

Belt path was developed by making an intersection curve from intersecting surfaces - see attached picture.  I've attempted to model with sweeps and lofts but don't know how to approach the necessary twisting that occurs.  Anyone have a good direction to suggest?
