  • Patent number: 7481226
    Abstract: A method for analysing cigarette smoking, which includes equipping a smoker with a portable assembly including a cigarette holder equipped with a detector to detect smoking-related parameters and a processor connected to the detectors. The processing module includes memory with date/time recording of the detected parameters and transfer devices for transferring data related to these parameters. A smoking test is performed during which the smoker equipped with the assembly smokes cigarettes with the cigarette holder over a period of time. Real-time detection is performed by the detectors and the results are stored so as to obtain a smoking profile specific to the smoker over the time period. The above data is then transferred to a processing center including a smoking machine, and the smoking machine is controlled using the transferred data so as to obtain the mechanical reproduction (duplication) of smoking in accordance with the smoking profile.

  • Patent number: 5592954
    Abstract: A cigarette making machine is provided with a pressure drop measuring unit (1) located at or close to the garniture of the making machine. The pressure drop of a gas stream of constant volume is introduced into the compacted tobacco rod beneath the format finger (2) on the making machine at a point at which that pressure drop measurement correlates with the bound pressure drop of the finished cigarette. The unbound cigarette pressure drop or draw resistance experienced by the smoker can be calculated using the bound tobacco rod pressure drop obtained by correlation with the measured pressure drop across the rod in an algorithim processed by calculation means. The degree of ventilation of the cigarette may also be utilised in the algorithim calculation. Comparator means allows the unbound cigarette pressure drop to be maintained within pre-set limits by varying cigarette parameters which affect the overall unbound cigarette pressure drop.

  • Patent number: 5369985
    Abstract: A sealing element for use in the testing of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body with an end portion having an axially movable end wall and an annular lip extending beyond the external surface of the end wall. The latter has a central opening constituting the inlet or the outlet of an axial passage for testing fluid. When the end of an article to be tested is caused to bear against the external surface of the end wall, the latter yields axially of the tubular body and causes the lip to flex radially inwardly into engagement with the periphery of the adjacent end of the article to be tested. In order to reduce the likelihood of damage to the end wall and/or the lip by sharp edges surrounding the ends of certain articles which are caused to bear against the external surface of the end wall, such external surface is provided with an annular recess which is inwardly adjacent the lip and can have a substantially semicircular cross-sectional outline.

    Abstract: A sealing element for the end portions of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body defining a longitudinally extending passage for the flow of air or another testing fluid from one end of an article being tested or in the opposite direction. The end face of the article being tested is engaged by a deformable membrane at one end of the passage, and such membrane has a central opening for the flow of testing fluid from or into an enlarged chamber between the membrane and an internal fluid deflecting baffle of the tubular body. The baffle causes the testing fluid to flow in the chamber radially inwardly toward or radially outwardly from the opening in the membrane and thus prevents the accumulation of tobacco particles and/or particles of filter material for tobacco smoke in the chamber. The stream of testing fluid in the major portion of the passage flows in the axial direction of the article being tested.

    Abstract: In an apparatus for detecting micro-holes of a cigarette having a filtered section, cigarettes are successively carried to a support section which is rotated and each of the cigarettes is supported between pads 14a and 14b. The supported cigarette is moved to a pre-pressuring stage in which one end face of the cigarette is closed and a pre-pressure is applied to other end face of the cigarette from a pre-pressure source. Therefore, the cigarette is reached to a measuring stage in which a measuring pressure is applied to the other end face of the cigarette so that air flows through micro-holes of the filter section and a reduced pressure is appeared in the one end of the cigarette. The measuring and reduces pressures are detected by pressure transducers and electrical signals from the transducers are proceed so that dilution value of the cigarette is calculated.

Parts of the laser beams are detected by photo detectors, respectively and the other parts of the laser beams are guided to polyhedron mirrors through first and second optical paths and divided into segment beams by the mirrors, respectively. The segments beams are focused on the corresponding cigarette so that micro-holes are formed on the cigarette. The cigarette is transferred to a dilution detection stage and the dilution is detected in mode, detection signals from the photodetector are processed and a first driving signal is generated. Thus, the two-dividing mirror is driver by a driving mechanism in accordance with the first driving signal so that the intensity of the laser beams guided in the first and second optical paths are maintained in substantially equal level.

The surface (40) is part of a body (22) which contains the microphone (54) and connecting leads (56, 58), together with a passage (36) allowing sound to reach the microphone. Air is bled through a small bore (52) and through a further bore (30) containing a sound-insulating filter (66) to provide a purging air flow in the passage (36).

    Abstract: A shower of fibrous material is directed against the underside of the lower reach of a foraminous endless belt conveyor so that the fibrous material gathers into a continuous stream which is attracted to the conveyor by suction and is moved longitudinally past a trimming device which removes the surplus. The density of the stream is monitored upstream and downstream of the trimming device, and the corresponding signals are processed in an evaluating circuit into additional signals which are indicative of the quantity of the removed surplus. The removed surplus is weighed and the weighing device generates signals also denoting the quantity of the surplus. Such signals are compared with the additional signals and further signals, which denote the differences between the intensities of the compared signals, are used to modify signals denoting the density of the stream downstream of the trimming device. The thus modified signals are used to adjust the trimming device.

  • Patent number: 4616662
    Abstract: A continuous rod-like filler is formed in a cigarette rod making machine on an endless foraminous belt conveyor by depositing a row of spaced-apart batches consisting of a first type of tobacco at one side of the conveyor, holding the batches by suction, and showering tobacco particles of a second type onto and/or into the spaces between the batches. The density of successive increments of the filler is monitored by a pneumatic and/or radiation type detector, and the thus obtained density signals are used to generate control signals which regulate the density of the filler as well as control signals which are used to influence the batches, if and when necessary. For this purpose, the density signals can be processed to single out those which are attributable to monitoring of the density of successive batches, and the singled out density signals are then analyzed and used to vary one or more parameters of the batches.
