A controlled deflection roll for forming a press with an opposed roll including an elongate tubular roll shell, an elongate support shaft extending longitudinally through the roll shell, and a fluid operated controllable load support means between the shaft and the shell, such as a piston with an open pressure hydrostatic oil interface facing the shell. The roll shell is constructed of a fabricated fiber reinforced matrix, and is comprised of a plurality of annular layers of fiber and matrix composite, so that the shell is of relatively light weight and has a reduced cross-machine bending stiffness.
