ABSTRACT:
The apparatus permits establishment of measuring values, yielding measuring values being representative of the material cross-section area solely of fiber slivers. A through-put duct converging, as seen, in the direction of transport of the fiber sliver is used into which two pressure measuring ducts merge at two measuring points at which the duct diameter is different. The two measuring ducts transmit measuring signals which are further processed in a division circuit means, which yields an output signal. The output signal is used for fiber sliver control or measuring purposes on machines processing fiber slivers or on spinning machines processing such fiber slivers further.
