Abstract
A flatness-measuring roll for detecting flatness defects of a metal strip extending and moving in a strip-travel direction has a roll body having a cylindrical outer surface and a central axis extending generally perpendicular to the strip-travel direction and about which the body is rotatable. A plurality of measuring bars axially spaced along the body, recessed in the body, and having outer faces flush with the body surface are each at least limitedly radially shiftable relative to the body. The bars are angularly elongated, each extend along a plane substantially perpendicular to the roll axis, and each have a constant width measured parallel to the roll axis over generally all of a respective total angular length. At least two respective force-measuring sensors are braced radially between each of the bars and the roll body.
