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, 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. A modified figure rail assembly and garniture entrance cone provide air flow toward the paper web being advanced through the garniture region of the cigarette making apparatus. Downwardly directed air exiting a plurality of air outlets in the finger rail create a zone of air turbulence the advancing paper web to maintains the paper web a distance away from the upper surface so that the additive material is retained on the paper web. Air exiting slots in the upper or top face of the garniture entrance cone also assist in maintaining the paper web away from the finger rail assembly. 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. 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.

A method of and system for detecting glue skips on tipping paper used to secure filters to cigarette tobacco rods and the rejection of defective cigarettes based thereon in which a particle radiation sensor is used to monitor the amount of glue applied to the tipping paper and a laser edge detector is used to monitor for proper alignment of the tipping paper during cigarette tipping operations in a typical cigarette manufacturing machine. The signals output from the particle radiation sensor are fed to a skip detection system which produces an output signal upon detecting a glue skip or a loss of glue. The glue skip or loss of glue signals as well as the paper edge detection signal produced by the laser edge detector are all fed to a programmable logic controller which, upon detecting a defective condition, generates a cigarette reject signal which is fed to the cigarette rod rejection system of the typical cigarette manufacturing machine in order to prevent the defective cigarettes from entering the stream of commerce.

A real-time cast sheet weight monitoring and control system in which the weight of a cast base sheet of wet laid tobacco slurry as well as the weight of a composite tobacco cast sheet formed by applying dry granular tobacco to the wet laid cast sheet prior to drying is disclosed in which two beta gauge sheet weight sensing devices are used to provide input signals to a controller which alternately uses those signals to monitor and control the weight of the cast base sheet by means of controlling the servo drive motors of a casting blade in a head box which is casting the wet laid sheet onto a stainless steel belt and which also uses those same signals to control the variable speed drive of a top loader for controlling the amount of dry granular tobacco which is uniformally applied to the wet laid cast base sheet prior to the drying of the composite tobacco cast sheet material formed thereby. The controller primarily monitors and controls the total weight of the composite tobacco cast sheet but interrupts that monitoring and control function periodically to monitor and control the weight of the wet laid cast base sheet.

Two olfactometers can simultaneously but independently provide stimulation to the eyes and nose of a human subject. Thus, a sample of air containing an odorant is delivered to the eyes only, nose only, or both eyes and nose of the subject. Physiological responses such as eye blink rate and breathing rate are observed and automatically recorded. Psychophysical responses such as ratings of ocular or nasal irritation also are recorded. The apparatus is useful in collecting data regarding fragrances and environmental air quality.
