Abstract:
An optical inspection system mounts on a cigarette making machine (200) or like system, and detects the presence of bands (5) having irregular widths or spacings. In response to the detection of irregular bands (5) the optical inspection system instructs the cigarette making machine (200) to reject cigarettes which will be subsequently made from portions of the cigarette paper containing the irregular bands. The optical inspection system includes a sensor (210) which can accommodate different types of cigarette paper, and band material having varying reflectance properties. In operation, sensor circuitry detects the range of voltages produced by a sensor detector (210), and formulates a peak value (or average peak value) for the range of voltages. The circuitry then takes a percentage of this peak value to form a threshold value. This threshold value is compared with the AC signal from the sensor detector (210). If the AC signal exceeds the threshold, then the circuitry asserts a signal to indicate that a band is present. The output of the sensor is fed to a computer (212). The computer detects whether the bands detected by the sensor (210) have regular band spacing and width.
Abstract:
A machine (10) for folding and applying onserts onto consumer goods such as cigarette packs (14) comprises a continuous roll of preprinted onserts and a transverse cutter assembly for cutting onsert segments from the continuous roll (18). Each onsert segment includes a pair of side-by-side preprinted onserts (12). A buckle folder receives each cut onsert segment (22) and folds that segment along at least one transverse fold line. A longitudinal cutter assembly longitudinally cuts each folded onsert segment into two individual onserts.
Abstract:
A machine (10) and process function to fill cavities (16) with metered amounts of particulate material is disclosed. An applicator wheel 18 includes a series of equally spaced apart peripheral pockets (24) each having a perforated bottom wall (32), and a vacuum manifold (34) inside the wheel includes a vacuum chamber 38 for supplying vacuum to the perforated bottom walls of the pockets as the wheel rotates. Particulate material (20) from a filling chamber (26) of such material outside the wheel is withdrawn into the pockets by the vacuum chamber. A downstream vacuum relief (48) on the vacuum manifold functions to discharge particulate material from the pockets into the cavities at a predetermined discharge location on the wheel. Adjustment structure (52, 54) is connected to rotatably adjust the position of the vacuum manifold within the applicator wheel to thereby advance or retard the discharge location depending upon the speed of the machine.
Abstract:
A cigarette filter assembly (10) comprises a hollow paper tube (12) with a spaced apart solid fiber plugs (14, 18, 22) inside the tube together with granular filter material (16, 20) in the spaces between the plugs. Energy activated adhesive is only between the solid filter plugs and interior surface portions of the tube. After the spaced apart solid fiber plugs are within the tube the adhesive is activated to secure the plugs to the tube. The energy activated adhesive is only on selected portions of the hollow tube where the solid fiber plugs are located or alternatively the adhesive is only on the exterior surface portions of the solid fiber plugs.
Abstract:
A method for making cigarettes comprises providing a supplying tubes to a tobacco rod maker from a hopper (151), supplying tobacco to the maker through an updraught chamber (143, 145) so that tobacco accumulates around the tubes. The tobacco is wrapped with paper (123) in a garniture (117) to form hollow wrapped tobacco rods having a tube running through them.

Abstract:
A filter component cutting system (10) comprises a supply hopper (14) of elongate filter rods (12) and a cutting drum (22) with spaced apart flutes (20) on an exterior surface of the drum for receiving the elongate filler rods. A transfer mechanism (16, 18) receives the elongate filter rods from the supply hopper and delivers the rods to the flutes on the cutting drum. At least one cutter (30) adjacent the cutting drum functions to cut the filter rods in to individual filter components as the cutting drum rotates. A process using the system is also disclosed.

Abstract:
A method and apparatus (8) for forming filter tubes (36) is disclosed. A filter element (10) is delivered to a flute (13) on a feed drum (12) having vacuum for securing the filter element thereto. First and second tube forming rollers (30,32) axially engage opposite ends of the filter element. A tipping drum (20) accepts and cuts a continuous paper web with a glue pattern thereon into paper pieces (22), and a cut paper piece is delivered to the filter element. The paper piece is then rolled around the filter element and the tube forming rollers to form a cylindrical shape. The tube forming rollers are axially disengaged to thereby produce a filter tube with hollow ends and a control positioned filter element.
