PROCESS FOR THE PURPOSE OF DETERMINING SURFACE EVENNESS ERRORS IN BAND AND PARTICULARLY STEEL AND METAL BAND AND FURTHER A SURFACE EVENNESS MEASURING ROLLER

摘要

The invention concerns a process and a surface evenness measuring roller for the purpose of determining surface evenness measurement errors in steel and meta l band comprising at least one measuring head having part measuring heads whic h part measuring heads are integrated respectively offset by 180.degree. into the roller mantel and supported on two force transmitters and are further separated from the roller mantle by means of a circumferential motion gap and are braced with respect to one another by means of at least one tie rod wherein in the course of a measurement of the band tensile stress distribution over the whole band width the band whic h band is subject to tension over its whole band width wraps around the surface evenne ss measuring roller with a predetermined arc of contact and thereby exerts pressing forces onto the surface evenness measuring roller from which pressing forces can be determined the band tension distribution.
