Abstract (en)
Wrappers of smoking articles have segments of band paper applied to modify the mass burn rate of the smoking article. A band paper web (1) is passed over an adhesive station (5) and then cut into segments (15) by a series of cutting blades (13). The segments are spaced apart by the differential rotational speeds of a vacuum roller 14 holding the segments and a roller (12) carrying the cutting blades (13). The segments are then adhered at intervals along a web of smoking article wrapper (17). The band paper (1) is selected to modify the burn rate of a smoking article produced from the wrapper when adhered thereto. <IMAGE>
