A cigarette making machine comprises means for showering tobacco onto two suction bands 610,612 to form tobacco sub-streams of similar width on the respective bands which are then merged to form a cigarette filler stream, and includes rod-forming means for enclosing the cigarette filler stream in a continuous wrapper to form a continuous cigarette rod, and means for forming or feeding onto at least one of the sub-streams, or between the sub-streams as or just before they merge, a layer 628 of core-forming material which is narrower than each of the sub-streams and is centrally located in relation thereto, whereby the core-forming material is surrounded by tobacco in the finished cigarette rod. This invention also encompasses the feeding of additional dense-ending quantities of tobacco instead of a core-forming layer.
A method of making cigarettes, in which tobacco is showered onto two suction bands to form two tobacco sub-streams of similar width which are then merged to form a cigarette filler stream which is used to form a continuous cigarette rod, including the step of forming or feeding onto at least one of the sub-streams a continuous or substantially continuous layer of material different from the tobacco of the sub-streams, the said layer or layers being narrower than each of the sub-streams and being centrally placed in relation thereto so that each of the sub-streams extends laterally beyond the lateral edges of the layer or layers, and so that the layer or layers will form a core in the finished cigarette filler stream surrounded by tobacco.
