摘要:
Apparatus for making ventilated cigarettes, includes a first perforator which is not readily susceptible to control and is arranged to perforate the tipping paper by which cigarettes are joined to filter portions, or to perforate the completed filter cigarettes. A controllable perforator is arranged to form additional perforations in the tipping paper prior to assembly of the filter cigarettes; and a control circuit is arranged to control the controllable perforator in response to a porosity measuring device and/or in response to a cigarette dilution testing device.
