Definitions

  • US Pat. No. 3,411,513 also discloses a method in which a moving, finished, tobacco rod wrapped in paper is deformed by an air stream and the associated tracking of the nozzle is detected.
  • the movement of the nozzle that occurs is related to the filling power of the tobacco and thus the hardness of the cigarette.
  • the statements made here are influenced by fluctuations in diameter and the porosity of the cigarette paper, so that there is only a few cases in which there is an exact correlation to the static measurement of hardness by determining the depth of penetration, as is known from the drawn article.
  • DE-OS 2 241 774 shows a device in which a force transducer, generally a strain gauge, is provided, which detects the deformation of the support bridge for the format finger.
  • a force transducer generally a strain gauge
  • DE-OS 2 457 141 shows a device which, at various points, detects the vertical and horizontal forces which the tobacco rod exerts on its guidance and in particular on the format finger. For example, the width of the gap between the front end of the format finger and a transducer, that is, the deflection of the front end of the format finger, is detected.
  • Tobacco rod exerts on his leadership and in particular on the format finger.
  • the width of the gap between the front end of the format finger and a transducer i.e. the deflection of the front end of the format finger, is detected.
  • the draw resistance of the cigarette is of great importance in the quality control of cigarettes, since it can be determined in a relatively simple manner from a draw resistance measurement whether a cigarette enables the desired draw volume.
  • the train volume A cigarette is in turn determined on the one hand by the smoking habits of the smoker and on the other hand by its draw resistance, which is made up of the draw resistance of the tobacco rod and the filter.
  • Another device for measuring the tensile resistance of a strand of tobacco fibers can be found in DE-AS 1 166 069 and has a source for a gas stream passing through the strand and a transducer for determining the pressure loss of the gas stream occurring at the strand at constant gas volume or the Passing gas volume with constant pressure loss.
  • a pump guides the air through the tobacco stream into a defined space of constant volume, which is formed between a trough through which the format tape pulls the tobacco stream and a part opposite it, such as a press shoe or tongue known per se.
  • the result is an extremely constant flow volume, as is necessary for the exact determination of the pressure loss on the line .
  • the nozzle with a critical flow is able to deliver the constant gas volume regardless of the back pressure that may arise.
  • the pressure sensor should be arranged perpendicular to the direction of flow of the gas flow into the strand. It is also possible to set up the pressure sensor outside of the actual machine area.
  • the hose or pipeline 20 for feeding the gas flow into the opening 18 of the format finger 12 is located in the front part of the rigid plate 14 and runs in a slight deviation from the vertical on the format finger 12 and thus on the transported tobacco rod, namely at an angle of approximately 80 to 83 ° to the tobacco rod.
  • a plurality of openings 18 can be provided in the format finger 12, which makes it possible, for example, to form an average value for the tensile resistance.
