Abstract
In an apparatus for detecting micro-holes of a cigarette having a filtered section, cigarettes are successively carried to a support section which is rotated and each of the cigarettes is supported between pads 14a and 14b. The supported cigarette is moved to a pre-pressuring stage in which one end face of the cigarette is closed and a pre-pressure is applied to other end face of the cigarette from a pre-pressure source. Therefore, the cigarette is reached to a measuring stage in which a measuring pressure is applied to the other end face of the cigarette so that air flows through micro-holes of the filter section and a reduced pressure is appeared in the one end of the cigarette. The measuring and reduces pressures are detected by pressure transducers and electrical signals from the transducers are proceed so that dilution value of the cigarette is calculated.
