ABSTRACT:
The invention relates to the correction of an error-prone measuring signal of a pair of scanning rollers. The measuring signal is influenced by the circularity error of the pair of scanning rollers and/or by the eccentric mounting of the pair of scanning rollers. The pair of scanning rollers is used to measure the thickness of a fiber fleece or fiber sliver on a pre-spinning machine in the textile industry. The occurrence of a periodic error value in the measuring signal due to circularity error and/or eccentricity of the pair of scanning rollers is detected. The error value is stored in a position-related manner for one revolution of the scanning rollers and the stored error value is used in the operation of the scanning rollers within the cycles of rotation for the correction of the current, position-synchronous measuring signals.
