Given a free-by-cyclic group GD FN A’ Z determined by any outer automorphism ’2 Out.FN/ which is represented by an expanding irreducible train-track map f , we construct a K.G;1/ 2‐complex X called the folded mapping torus of f , and equip it with a semiflow. We show that X enjoys many similar properties to those proven by Thurston and Fried for the mapping torus of a pseudo-Anosov homeomorphism. In particular, we construct an open, convex cone A H 1 .XIR/D Hom.GIR/ containing the homomorphism u0W G! Z having ker.u0/D FN , a homology class 2 H1.XIR/, and a continuous, convex, homogeneous of degree 1 function HW A! R with the following properties. Given any primitive integral class u2 A there is a graph Cu X such that:
