Method for determining flatness defects in strips, in particular steel and metal strips, and flatness measuring roll

摘要

It is a method and a flatness measuring roll for the determination of flatness measurement errors in steel and metal strips, with at least one measuring body with two offset by 180 DEG integrated in the roller shell and supported on force transducers part measuring bodies, which decoupled from the roller shell by a circumferential movement gap and at least one tie rod are braced with each other, wherein in the course of a measurement of the strip tension distribution over the bandwidth standing over the entire band under tension band wraps around the flatness measuring roll with a predetermined wrap angle and thereby exerts contact forces on the flatness measuring roll, from which the tape tension can be determined.
