Abstract: A reconstituted tobacco material is manufactured by extracting a natural tobacco material with an extracting solvent to obtain an extraction residue and a tobacco extracted liquid containing desired components and undesired components including tobacco-specific nitrosamines, subjecting the tobacco extracted liquid to a fractionating treatment by means of a reverse osmosis membrane to obtain a membrane impermeable fraction containing the desired components and depleted in the undesired components and a membrane permeable fraction depleted in the desired components and enriched in the undesired components, controlling the tobacco extracted liquid during the fractionating treatment to have a temperature suitable for the fractionating treatment, removing precipitates, which are precipitated in the tobacco extracted liquid during the fractionating treatment, from the tobacco extracted liquid, preparing a reconstituted tobacco web containing the extraction residue, and adding the membrane impermeable fraction to th

Abstract: A wrapping paper inspection apparatus includes a nozzle arranged in a wrapping-paper discharge path, in which wrapping paper is wound and continuously discharged, for wetting one side of the wrapping paper with a liquid; an image pickup section for irradiating light to the wrapping paper wetted with the liquid by the nozzle, detecting light transmitted through or reflected from the wrapping paper, and generating an image signal; and a wrapping paper inspection section for determining defects in wrapping paper portions applied or affixed with a low flame spread material, from the image signal generated by the image pickup section, to thereby inspect such defects easily and reliably. This inspection apparatus can be mounted to a tobacco wrapping machine.

Abstract: A mixture identification system for detecting foreign matter admixed in a tobacco material includes a conveyor for conveying the material, an irradiation device for irradiating infrared light toward an inspection line extending across the conveyor, an infrared camera device for receiving the infrared light reflected from the tobacco material passing across the inspection line and outputting image data of the material based on the received infrared light, and a discrimination circuit for detecting foreign matter in the material based on the output from the camera device. The infrared camera device has infrared filters for receiving the infrared light reflected from the tobacco material and allowing only respective specific wavelengths to pass therethrough, and optical line sensors for receiving the infrared light passed through the respective filters.

Abstract: A cigarette making machine includes a web roll (8) from which a web W having bands previously formed is drawn, and a suction brake (14) arranged between the web roll (8) and a garniture tape (2) of a wrapping section (6). When a band (B) for a cigarette (C) is out of a proper region (CR), the suction brake increases the tension to be applied to the web W to elongate the web to thereby bring the location of each band (b) back to within the proper region.

Abstract: A mixture identification system for detecting foreign matter admixed in a tobacco material (T) includes a conveyor (2) for conveying the material (T), an irradiation device (6) for irradiating infrared light toward an inspection line (IL) extending across the conveyor (2), an infrared camera device (10) for receiving the infrared light reflected from the tobacco material (T) passing across the inspection line (IL) and outputting image data of the material (T) based on the received infrared light, and a discrimination circuit (96) for detecting foreign matter in the material (T) based on the output from the camera device (10). The infrared camera device (10) has infrared filters (70, 76, 82) for receiving the infrared light reflected from the tobacco material (T) and allowing only respective specific wavelengths to pass therethrough, and optical line sensors (72, 78, 84) for receiving the infrared light passed through the respective filters (70, 76, 82).

Abstract: An apparatus for automatically inspecting abnormalities in the external surface of cylindrical objects. The apparatus inspects the appearance of a cylindrical object using image processing. The apparatus includes a transporter and a CCD camera. The transporter rotates the cylindrical object about an axis of the cylindrical object. The CCD camera picks up images showing the appearance of the inspected cylindrical object. The images include picture elements, and each picture element has a corresponding luminance. The apparatus further includes a controller. The controller generates at least one masking window to mask at least one predetermined portion of at least one image; generates at least one luminance sum for each image by adding, for each image, the luminance of a predetermined number of picture elements in unmasked portions of the image; compares each luminance sum to a predetermined threshold; and judges whether the cylindrical object includes a defect based on a result of each comparison.
