Verfahren und Vorrichtung zur kontinuierlichen Messung der Masse eines bewegten Faserbandes

The description relates to a process and device for the continuous measurement of the mass of a moving fibre strip (6) in a guide component (7) surrounding the fibre strip, in which the fibre strip is transversely irradiated by radiators (31, 32... 3n), the residual radiation leaving the fibre strip is measured by a measuring component (4) operating on a characteristic determined by physical laws, the measured residual radiation is converted into electric signals and the electric signals are taken to an electronic processing unit (2) for display, storage and/or adjusting processes. In order to improve the results of measurement, the process and the device are modified in such a way that the intensity of the radiator is set for a part of fibre strips on the presentation of a fibre strip representing the part in the guide component depending on a preselected electric value which represents the median of the selected measurement range.
