A method for adding a flavouring substance to a tobacco rod and apparatus for carrying out the method.

摘要

In order to provide when smoking a cigarette a substantially uniform concentration of the flavouring substance or substances supplied to the tobacco rod (23) in the form of at least one flavouring substance, the flow of flavouring 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.
