Abstract
The disclosed method and apparatus measures radial deviations along the axial length of a work roll with a number of axially spaced displacement detectors and at least three axially spaced motion detectors mounted ona detector mount that moves axially along the roll. A calculator responds to the motion detectors to determine errors in the motion of the mount to correct the output of the detectors and sums the deviators to generate overall deviations.
