ABSTRACT:
A rolling mill roll having adjustable axial compliance is formed by a sleeve in the bore of which is located a stiffening arbor. The arbor is an interference fit with the bore of the sleeve over a limited central part of the roll but on each side of that central part is stepped in diameter to form, at each side, a divergent stepped space between arbor and sleeve. That space is occupied by a number of annular wedges which normally do not give support to the sleeve. At each end of the roll there is a hydraulic actuator which applies axial force to the wedges at that side and expand the wedges progressively against the sleeve. By varying the force applied by each actuator the number of wedges supporting the sleeve can be adjusted, thereby to vary the length of the sleeve supported by the arbor.
