ABSTRACT OF THE DISCLOSURE An apparatus for the continuous measurement of the draw resistance of acigarette, comprising transducer which detects the pressure drop of a gas stream with constant volume, said gas stream being introduced at a format finger of a rod-producing machine into a rod of tobacco fibres. The measured value depending on the flow resistance of said rod is continuously determined and correlates very well with the usual static measurement of the draw resistance of cigarettes, i.e. of the tobacco rod of a cigarette, so that this continuous draw resistance measurement during the cigarette production replaces not only the conventional random check but can also be used for controlling the production operation.
