Abstract
In an apparatus for measuring the mass of fibre material passing through a spinning preparation machine or system or through a nonwoven production device, at least one microwave resonator is provided. In order to improve measurement of the mass of fibre material in a cleaning system, especially between a bale opener and carding machine, and to use that measurement for closed-loop and/or open-loop control, the fibre material is present in the form of fibre flocks and the fibre flocks pass through a measurement pathway having a measuring device having the at least one microwave resonator.
