Abstract
A rider roll beam is mounted in a pair of opposed frames having substantially vertical guide surfaces and the axial ends of the beam are provided with curved surfaces cooperating with the vertical guide surfaces to permit the beam to pivot about a horizontal axis located at about the midpoint of the machine and extending substantially perpendicular to the longitudinal axis of the beam. The rider roll beam is also provided with tongues that are received in glide slots having substantially vertical sidewalls so that the beam cannot pivot about its longitudinal axis or a substantially vertical axis. Preferaly the rider roll beam will be directly supported at each end by a hydraulic cylinder that raises and lowers each end of beam substantially independently of the other.
