A cleaning unit for machines used in tobacco industry, configured to remove contaminations of a loose material from rod-like elements (S1, S2) arranged in a moving train (ST2), the train (ST2) comprising rod-like elements (S1, S2) separated with spaces (43) filled with the loose material, the train (ST2) being partially wrapped by a wrapper (101), wherein the cleaning unit comprises at least one suction nozzle (55, 89) for collecting the contaminations of the loose material, characterized in that the cleaning unit further comprises a shifting mechanism configured to shift covering elements (52, 64, 84, 85, 85, 91) to positions in which the covering elements (52, 64, 84, 85, 85, 91) at least partially cover spaces (43) filled with the loose material between the rod-like elements (S1, S2) during the movement of the train (ST2) in a vicinity of the suction nozzle (55, 89).

The present invention relates to an independent, tobacco addiction-dispelling and tobacco toxicity-detoxifying filter, and a process for preparing the same. Said process is characterized in enabling organic substances in tea leaves to exude by air entraining and heating, immersing with a suitable amount of water and stirring, enhancing the effect on dispelling tobacco addiction and detoxifying tobacco toxicity, adding a part of celluloses by using the adhesiveness and water resistant effect of the exuded organic substances to produce tea powder, tea slices and tea particles; packaging the tea powder, tea slices, tea particles and active substances and additives within the filter via a device to form a cigarette holder, a cigarette filter rod or a cigarette holder bullet core having an absorbing resistance controlled to be within the applicable scope. During smoking, the effective substances in the filter volatilizes and sublimes via heat and water vapor in the smoke, sucking force of smoking or an electronic smoking equipment and are absorbed when entering respiratory tract, so as to inhibit nicotine receptor and to achieve the cessation and detoxification effect on cigarette smoking.

Machine and method for producing substantially cylindrical articles of the tobacco processing industry; a material with cavities is fed, along a given path, through an insertion station, where powder material is inserted into the cavities, so as to obtain a strand, and through a wrapping station, in the area of which a strip is wrapped around the strand; the powder material is inserted into each cavity by a relative insertion unit, which moves in a synchronous manner along a coupling portion of the given path.

A tobacco rod, an aerosol-generating article including the same, and an aerosol generation device used with the aerosol-generating article are provided. The tobacco rod according to some embodiments of the present disclosure may include a first filter segment, a second filter segment disposed upstream of the first filter segment, and a cavity segment which is formed by the first filter segment and the second filter segment and filled with tobacco granules.

A volumetric metering device includes a hopper adapted to hold a supply of granular material, the hopper having an outlet; a rotating wheel located in communication with the outlet, the rotating wheel having an outer periphery and a plurality of metering cavities distributed around the outer periphery, each metering cavity having an open bottom portion; and a plurality of metering valves located around the outer periphery of the rotating wheel with each metering valve located in registry with one of the metering cavities. Each metering valve is movable between a loading position wherein the metering valve blocks the open bottom portion of the metering cavity, and an unloading position wherein the granular material dispenses from the metering cavity through the metering valve. Other features and related methods are also described.

The present disclosure provides a flavored sheet including a flavor component and activated carbon, a method of manufacturing the flavored sheet, a smoking article filter including the flavored sheet, and a smoking article including the flavored sheet. The flavor component may be included in an amount of 10 to 40 wt % (wt %) and the activated carbon may be included in an amount of 1 to 10 wt % based on a weight of the flavored sheet, and the flavored sheet may have an enhanced fragrance retention.

A smoking article filter has a flavoring agent uniformly distributed in the smoking article filter, wherein the flavoring agent is in a solid state at room temperature and includes at least one natural wax and a flavoring component soaked into the at least one natural wax. Also provided are a smoking article including the smoking article filter and a method of manufacturing a smoking article.

Some embodiments of the present disclosure provide a smoking article filter having a flavoring agent uniformly distributed in the smoking article filter, which is in a solid state at room temperature and includes at least one natural wax and a flavoring component soaked into the at least one natural wax.
