  • Patent number: 7004177
    Abstract: The invention relates to a method for detecting and selecting foreign parts in cigarettes, in which the tobacco is exposed in the vicinity of the cigarette maker to microwave radiation and both a signal SD relating to the tobacco density and a signal SF relating to the tobacco moisture are generated. The density signal SD and moisture signal SF are evaluated in combination with one another for the detection of the presence or absence of foreign parts in the tobacco.
