A device for rolling a sheet includes a main casing which extends between a front face and a rear face and includes a cap which includes a first receiving slot, a sliding element translationally movably mounted in the main casing, from the front face of the casing and including a shell including a second receiving slot, a rotary element rotatably movably mounted and including a shaft housed inside the main casing, from the rear face of the casing, the shaft including an open third receiving slot, and a stop surface. In the closed position of the rolling device, the first and second slots are aligned along the same vertical plane.

A backing with corrugations on a first surface. The corrugations are parallel and each has an airspace along an entire longitudinal length. A second surface of the backing includes perforations or scores oriented perpendicularly or parallel to the corrugations. The corrugations or scores are fold lines or frangible tear lines. The airspaces may also include a filter material. The second surface of the backing may be adhered to a corner of a rolling paper on the surface but opposite edge as a gum strip. The corrugations are parallel to the gum strip.

This filler element is used in a flavor inhaler, and comprises: a folded part in which one sheet composed of a nonwoven fabric has been folded in the width direction Z intersecting the longitudinal direction X thereof, and the diameter thereof has been reduced to a size not greater than the diameter of the filler element; and wrapping paper that is wrapped on the folded part. A section of the folded part in the circumferential direction thereof has an opening that is open along the axial direction X of the folded part, and an additive is placed on the interior of the folded part via the opening.

A method of manufacturing a compressed rod of web material for the filter rod of an aerosol-generating article, comprising: supplying a feed of web material from a supply apparatus; drawing the web material through a filter rod manufacturing apparatus; introducing a curved ridge into the central portion of the width wise cross-section of the web material as it approaches contact with the interior of a folding funnel, by drawing the web material across a forming surface of a former that contacts a central portion of the web material, in which the forming surface deflects the central portion of the web material from a line extending between where the web material leaves the supply apparatus and the center of an outlet of the folding funnel; and folding the web material in the folding funnel to form a compressed rod of web material.

The invention discloses a filter-tipped cigarette comprising a filter tip. The filter tip comprises a plurality of filter elements twisted together by mutually winding. All the filter elements are cellulose acetate fiber bundles. In the invention, since the filter elements are disposed in the way of winding, a total length of the filter elements is increased, a travel of a smoke passing through the filter elements is thereby increased, and thus harmful ingredients in the cigarette are filtered more thoroughly.

A method and device for forming a cigarette filter rod. The method is as follows: in a process of continuously conveying forward cigarette filter materials that tend to converge to have a rod shape, multiple granular additives are continuously output in accordance with a certain time interval, and are sprayed into the cigarette filter materials that converge forwards under the action of continuous transporting flows, so that after the cigarette filter materials converge to form a continuous filter rod, multiple groups of additive unit combinations formed of different granular additive units are embedded in an axial direction of the filter rod. With the method and device for forming a cigarette filter rod, a filter rod containing multiple granular additives can be formed in one step; multiple granular additives can be combined and arranged in any way along an axial direction of the filter rod; dosage positions and intervals of various granular additives can be adjusted and changed randomly; a production process is simplified and the production cost is reduced.

The invention relates to a cardboard filter (1) for cigarettes, formed by folding, winding and gluing a cardboard strip (2). According to the invention, the cardboard strip (2) is folded to form a central portion (21) having a series of lobes (3, 4, 5, 6, 7) angularly equally distributed around a central axis (22) of the filter (2) and a peripheral portion (23) surrounding the central portion (21), the lobes (3, 4, 5, 6, 7) and the peripheral portion (23) delimiting gas passage channels (24) around the central axis (22).

A device for burning smoking material and inhaling the resulting smoke is disclosed. The device can include an hollow member formed from a material having an internal elongated cavity extending from an open end to a closed end. The elongated cavity can be configured to receive smoking material. The smoking accessory can include a filter disposed within the hollow member and defining the closed end. The filter can comprise material formed from Areca plants. The filter can have an cavity formed in the filter for housing a capsule containing a flavoring agent.

A machine for making a continuous tubular element with filling from web material, including first and second means for feeding respective continuous webs, a forming station configured to perform a folding and/or deformation of a first continuous web in a shaped configuration, and a wrapping station wherein the second continuous web is wound in a tubular shape around the first continuous shaped web to obtain the continuous tubular element. Upstream of the wrapping station there is a first gluing device configured to apply at least one longitudinal line of glue on at least one of the continuous webs in such a way as to define at least one gluing zone, said longitudinal line of glue being positioned in such a way as to coincide with a zone of superposing and contact between the two continuous webs feeding out of the wrapping station.

The present invention provides a mouthpiece or filter element (e.g., for a smoking article such as a cigarette, a tobacco heating product, a HNB product) comprising a longitudinally extending (e.g., substantially cylindrical) hollow tube of paper; a filler layer comprising paper filtering material and/or other biodegradable filtering material engaged around the hollow tube along the full (e.g., longitudinal) length of the hollow tube; and a wrapper (e.g., plugwrap) engaged around the filler layer along the full (e.g., longitudinal) length of the filler layer, wherein the hollow tube, the filler layer and the wrapper are the same length.
