simple bend deform

[doe]

trying to get into ICE by building up a bend deform with curling. but i am struggling with the breakdown of this problem. i guess that is the major problem anyone without proper math knowledge has.
any hints?

just want to bump this up.
noone who could help me out with a hint in the right direction?
trying to build something i could bend around multiple nulls ( nulls represent the rotation pivot)
just want to flod some banana leaves with it ;)

here's my take on it.
driven by groups, which is fairly flexible and allows for a lot of different rolls on the same object, while only executing one deform network.
