<p>The apparatus permits establishment of measuring values, yielding measuring values being representative of the material cross-section area solely of fibre slivers. A throughput duct converging, as seen in the direction of transport of the fibre sliver, is used into which two pressure measuring ducts (5 and 6) merge at two measuring points (3 and 4) at which the duct diameter is different. The two measuring ducts transmit measuring signals which are further processed in a division circuit arrangement (11), which yields an output signal (12). The output signal is used for fibre sliver control or measuring purposes on machines processing fibre slivers or on spinning machines processing such fibre slivers further. </p> |
