摘要： A sheet for a smoking article filter containing:
a fiber, particles with a particle size of 20 to 200 mesh, and an adhesive,
when the weight of the particles present in a region from the center in the thickness direction to one surface divided by the weight of total particles is defined as distribution ratio CA, and
the weight of the particles present in a region from the center in the thickness direction to the other surface divided by the weight of total particles is defined as distribution ratio CB,
CA > CB is satisfied.-

摘要： Provided is a technique related to a filter for cigarette product that can reversibly change the fragrance inhaling taste. The filter for cigarette product includes: a mouthpiece end side-filter material that is arranged on the mouthpiece end side; and a front stage-filter material that is arranged at the front stage of a hollow filter material and filters mainstream smoke. The mouthpiece end side-filter material has a low air flow-resistance unit that is arranged in a part of a cross section from a front end surface to a rear end surface and having a relatively low air flow-resistance, and a high air flow-resistance unit that is arranged in the remainder of the cross section from the front end surface to the rear end surface and having a higher air flow-resistance than the low air flow-resistance unit. At least on the rear end surface of the mouthpiece end side-filter material, the low air flow-resistance unit is arranged only in one semicircular area, of two parts into which the cross section of the mouthpiece end side-filter material is divided.

摘要： This filter for a tobacco product has: a fine-powder-containing article in which there is clumped a raw powder including a taste component and/or an aroma component, the fine-powder-containing article being formed into a powder by the application of force; a cavity in which the fine-powder-containing article is disposed; and a suction port filter part installed downstream of the cavity, the suction port filter part enabling communication between the cavity and an end of a suction port and having formed along the axial direction thereof a fine powder supply path for supplying fine powder from the cavity to the end of the suction port. The fine powder supply path includes a central connection part positioned at the center of a transverse cross-section of the suction port filter part, and a plurality of hole parts extending in mutually different directions from the central connection part toward the outer periphery of the transverse cross-section.

摘要： A filter manufacturing machine includes a forming device (3) for forming filter tow (5) into a hollow rod-shaped continuous filter body, a forming tube (12) included in the forming device (3) and having a tubular forming path (2) through which the filter tow (5) is passed while being brought together, a mandrel (13) arranged in the forming tube (12) and forming the tubular forming path (2) in cooperation with the forming tube (12), and a heat treating section (17) included in the forming tube (12) and configured to heat the filter tow (5) while the filter tow passes through the tubular forming path (2). The mandrel (13) has a small-diameter portion (13a) located at the inlet of the forming tube (12), a large-diameter portion (13b) located at the outlet of the forming tube (12), and a diameter expansion portion (6) located between the small-and large-diameter portions (13a, 13b). The diameter expansion portion (6) is located downstream of the heat treating section (17) as viewed in the moving direction of the filter tow (5).
