Abstract (en)
[origin: EP0059042A1] In a filter cigarette, channels for secondary or dilution air are formed by slits (6 to 12) in an intermediate sheet (4) interposed between the filter rod (1) and the tipping paper (20). Perforations (26) in the tipping paper communicate with the channels. The intermediate sheet may be of paper and between 0.1 and 0.6 mm in thickness, and preferably surrounds the filter rod without an overlap and leaves a tolerance gap (15) between itself and the tobacco rod (17).
