In a cigarette maker, shredded tobacco passes through a feed and transport section toward a unit by which divided particles of the tobacco are gathered into at least one stream providing the filler for cigarettes. By positioning one or more sensors either along the feed and transport section or at a point upstream, relative to the feed direction of the tobacco, it becomes possible to identify the type of tobacco being handled at any given moment, so that when production schedules include a changeover from one brand to another, supervisors can be certain that the right type of tobacco has been selected, and ensure that different types of tobacco will not mingle.
