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

Abstract: The filter for cigarette product includes a mouthpiece end side-filter material and a front stage-filter material. 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.

Abstract: 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 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 cross-section.
