Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive materials, which can have the forms of liquid or paste formulations (e.g., aqueous formulations incorporating starch or modified starch), are applied to a continuous paper web on the cigarette making apparatus. The formulation is applied to the paper web using application apparatus possessing rollers a series of roller. For example, additive material is applied to the roll face of a transfer roller due to roll interaction of that transfer roller with a pick-up roller; roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller; and additive material from the application roller is transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer is used to dry the additive material that has been applied to the paper web. The radiant dryer is located on one component of a two component assembly that is used to manufacture cigarettes. A first component of the two component assembly provides a source of paper web, applies additive material to that web in a pattern and dries the paper web; while a second component receives the paper web, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. An alternate assembly system provides a source of paper web, applies additive material to that web in a pattern, dries the paper web, and winds the treated paper web on to a bobbin; and that bobbin is later used to provide a source of paper web on a cigarette making machine unrolls that bobbin, receives the treated paper web from that bobbin, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. Spectrometric techniques are used to ensure proper registration of the additive material on the cigarette rods so manufactured, and to ensure proper quality of those cigarettes.

The additive materials, which can have the forms of liquid or paste formulations (e.g., aqueous formulations incorporating starch or modified starch), are applied to a continuous paper web on the cigarette making apparatus. The formulation is applied to the paper web using application apparatus possessing rollers, and one of those rollers has 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. For example, additive material located in the recessed pockets of a first roller is transferred in a controlled manner to the roll face of a second roller in roll contact with that first roller; and the additive material on the roll face of the second roller is transferred to desired locations on the surface of the paper web. The formulation also can be applied to a continuous moving paper web using an application apparatus possessing four rollers. For example, additive material is applied to the roll face of a transfer roller due to roll interaction of that transfer roller with a pick-up roller; roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller; and additive material from the application roller is transferred to the paper web that passes between the application roller and a back-up roller.

Forming method of no-material-head shaft piece by cross wedge rolling
The invention discloses a forming method of a no-material-head shaft piece by cross wedge rolling. The forming method is characterized in that firstly the two ends of a blank are rolled into a linear frustum shape with an inward large head and an outward small head, simultaneously the whole length of the blank keep constant, then the blank with the two ends shaped like the linear frustum is rolled in the mold from the central section of the blank to the two ends of the blank according to the conventional cross wedge rolling method, and the no-material-head shaft piece meeting the requirementsis obtained. The forming method has the advantages that as the two ends of the blank are rolled into the linear frustum shape with the inward large head and the outward small head firstly in the rolling, consistent flowing between surface metal and core metal of a rolled piece in the following rolling process is guaranteed, the end part of the rolled piece generates a concave core, so that the rolled piece does not generate material heads, the material utilization rate is improved, the production cost is reduced, and the surface quality of the rolled shaft piece is good. In the forming method, the material utilization rate can be improved by more than 95%.
