ABSTRACT OF THE DISCLOSURE A deflection-controlled roll has a roll shell rotat- ably mounted about a fixed beam and supported on a plurality of hydraulic piston support devices positioned along the roll for exerting forces between the beam and the roll shell. The roll shell is formed of an elastomeric material and is provided with a stiffener insert embedded in the material of the shell for in- creasing its resistance to circumferential deformation. The stiffner insert may include a metal helical coil extending about the axis of the roll shell or a corrugated tube coaxial with the shell. The roll shell may also include a plurality of annular inserts spaced along the interior of the shell the inner sur- faces of which form bearing surfaces for the support devices.
