Abstract:
1. A method of characterizing a deflection-compensated roll comprising the steps of: measuring nip forces with a plurality of nip force sensors positioned in a nip between a deflection-compensated roll shell and a backing element, wherein the deflection-compensated roll shell is mounted about a support beam; urging the support beam toward the backing element, and simultaneously measuring loads applied by loading arms to urge the support beam towards the backing element; measuring hydraulic pressure from internal to the roll shell, wherein the measured hydraulic pressure is used to support one or more pistons which operate to support the roll shell; and displaying on a display screen at least one value from; the plurality of nip force sensors, from the measured loads applied to loading arms, and from the measured hydraulic pressure from internal to the roll shell.
