摘要： Webs which are to be converted into wrappers for filter rod sections, cigars, cigarillos or cigarettes, or the wrappers of such articles, are perforated by one or more laser beams in the machine wherein the articles are produced. The permeability of wrappers can be changed by increasing or reducing the number of holes and/or by increasing or reducing the size of holes in each wrapper. The permeability of the wrappers of finished articles is monitored and the intensity of laser beam or beams is automatically adjusted when the monitored permeability deviates from a desired value. The perforations are formed for the purpose of admitting cool atmospheric air which influences the quantity of nicotine and condensate in the column of smoke. The perforations are disposed close to or in the filter plugs of filter cigarettes, cigars or cigarillos, or close to one or both ends of each filter rod section or plain cigarette, depending on the length of such articles.

摘要： Filter cigarettes which are grouped in the form of one or more rows on their way to the draping station or stations of a packing machine are transported sideways past a testing station between two testing units each of which has a discrete detector for each row of cigarettes in a group. Each detector has a source of light, a photoelectric transducer, and a bundle of fiber optics which convey light beams from the source against the respective end faces of cigarettes advancing between the two testing units and which convey reflected light to the respective transducer so that the latter generates signals denoting the characteristics, the presence or absence of cigarettes. Such signals are compared with a reference signal denoting the characteristics of satisfactory cigarettes, and the groups wherein one or more cigarettes have caused the generation of signals deviating excessively from the reference signal are expelled from the conveyor prior to reaching the first draping station of the packing machine. The extent of contamination by tobacco dust or the like of optical elements through which the light beams pass is monitored, and the signals which denote the extent of detected contamination are used to modify the signals denoting the characteristics of the tested cigarettes, to effect automatic cleaning of the optical elements and/or to arrest the packing machine.
