Abstract
Abstract A method and apparatus are disclosed for applying foamed material to tobacco, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker at the garniture mouth (21) or through the short tongue (30) or through both, or at the chimney (10). Addition of a foamed material to the tobacco, during the cigarette making process, results in a cigarette in which the material added is more uniformly distributed.
