Apparatus for measuring the density of a tobacco stream

摘要: The density of a tobacco stream which is advanced by foraminous conveyor toward the surplus removing station cigarette rod making machine measured one or more detectors each having sources infrared light and photoelectric transducers. In order to avoid generation distorted signals in response impingement high-intensity radiation upon transducer transducers, out line with path direct propagation from respective source successive increments stream. transducers receive scattered and/or reflected particles Signals are used regulate quantity removed
