Abstract
An apparatus for forming a tobacco stream in cigarette making machines or the like to production of rod-shaped smokers' articles comprising a tobacco channel with an air-permeable channel bottom which extends substantially horizontally from a stream building section to a stream discharging location and above which the lower reach of an air-permeable tobacco band is guided. The tobacco channel cooperates with a suction chamber to generate suction which holds the built-up tobacco stream. In order to maintain the structure of the stream, even at high transporting speeds, there are provided means for reducing suction through the bottom of the channel outside of the stream building section.
