A tree-strip of finite cone type is the product of a tree of finite cone type with a finite set. We consider random Schrodinger operators on these tree-strips, similar to the Anderson model. We prove that for small disorder, the spectrum is almost surely, purely, absolutely continuous in a certain set.
