Abstract
A relatively wide first layer of tobacco particles is broken up into several narrower second and several narrower third layers. The second layers are converted into a first tobacco filler stream which is trimmed to form a rod-like filler ready to be draped into a web of cigarette paper, and the third layers are converted into a second tobacco filler stream which is ready to be trimmed to form a rod-like filler ready to be draped into a web of cigarette paper. The tobacco layers are caused to advance along and closely follow concave sides of guide surfaces and are propelled along the respective surfaces by streams of compressed air. Subdivision of the first layer into several second and several third layers reduces the likelihood of unmixing or dehomogenization of the mixtures of tobacco particles which are about to be converted into plural tobacco filler streams.
