ABSTRACT:
A machine for making oval cigarettes has a channel, through which tobacco is showered towards a suction conveyor, formed by walls which diverge in cross-section along at least part of the tobacco-receiving section of the conveyor so as to form a filler stream which is denser at the middle than it is at the sides, the angle of divergence being preferably at least 15.degree. (e.g. 19.degree.). In the garniture area of the machine, the cigarette filler stream is initially shaped without being significantly compressed, and is then compressed vertically by a tongue to form the desired oval cross-section (with a horizontal major axis); while the filler stream is being vertically compressed by the tongue, the garniture bed allows the radius of curvature of the underneath surface of the filler stream to increase progressively to the final value.
