Abstract
A fibre band or sliver is passed through a defined opening of a measuring station. Said opening has a cross section smaller than the diameter of the fibre band, so that the band contacts the walls of said opening which thereby defines a measuring cross section. The fibre band while passing said opening is transilluminated by at least one light source. The transmitted light intensity is measured by a light receiver and is detected as a measure for the quantity of the fibre material present in said cross section.
