Abstract
In order to provide when smoking a cigarette a substantially uniform concentration of the flavoring substance or substances supplied to the tobacco rod (23) in the form of at least one flavoring substance, the flow of flavoring substance is controlled, in accordance with the invention, periodically between a maximum and a minimum flow. The maximum flow is applied to those parts (36) of the tobacco rod which each include the tip-end of a cigarette, whereas the minimum flow is applied to the opposite end part (37) of the cigarette.
