Abstract
The profile of a measurement roll is stored in a computer during a calibration revolution. On revolution with fiber mats to be measured, the computer reduces the measured values exactly by the measured values of the corresponding calibration profile. The measurement result obtained does not depend on the production quality of the measurement roll.
