US Patent 7077145 Equipment and methods for manufacturing cigarettes

Cigarettes manufactured using modified automated cigarette making apparatus can possess smokable rods having paper wrapping materials having additive materials applied as patterns. The additive materials, which can have the forms of liquid or paste formulations, are applied to a continuous paper web. The formulation can be applied to the paper web using application apparatus possessing rollers. One of those rollers can have a series of pockets in its roll face to receive additive formulation from a reservoir and to define the pattern of the formulation on the paper. A radiant dryer can be used to dry the additive material applied to the paper web. The radiant dryer can be located on one component of a two component assembly used to manufacture cigarettes.
