Abstract (en)
[origin: US2003106561A1] The filler of a cigarette rod has a tubular portion made of shredded tobacco and surrounding at least one row of spherical inserts made of aromatic material or aerosol. The tubular portion is made by feeding tobacco shreds against the underside of the horizontal lower reach of a foraminous conveyor belt advancing beneath a suction chamber to accumulate a first layer of shreds. The inserts are delivered to the underside of the first layer and are attracted thereto by suction. A second layer of shredded tobacco is assembled by showering shreds against the underside of the first layer where the second layer underlies the spherical inserts. The thus obtained filler is draped into a web of wrapping material to form a cigarette rod ready to be subdivided into sections of unit or multiple unit length. The spherical inserts are expelled from a revolving receptacle under the action of centrifugal force to form a row which is conveyed toward the underside of and advances with the first layer.
