ABSTRACT:
The apparatus employs two cutting discs which are spaced apart from each other laterally to sever plugs of different lengths from a travelling rod of filter material. The plugs alternate in size, for example, between 24 millimeters and 14 millimeters and are subsequently spaced apart so as to receive charcoal or other particulate filter material in the intermediate spaces. The resulting filter has the charcoal chamber closer to the tobacco end of the cigarette than to the exposed end of the cigarette. The cutting discs are mounted on a drum which rotates in synchronism with a recessed ledger through which the respective cutting discs pass to sever the travelling rod of filter material.
