The forming apparatus comprises a feed path for continuously feeding a continuous tow material along a transport direction, a forming device connected to a downstream end of the feed path and adapted to form the continuous tow material into a continuous tubular rod. The forming device comprises a tubular element adapted to allow the continuous tow material to pass through the tubular element to form the continuous tubular rod and a steam generator adapted to generate overheated steam. The steam generator is in fluid connection with the tubular element to provide overheated steam to the continuous tow material. The forming device further comprises several fluid conduits to provide overheated steam from the steam generator to several injection sites arranged along a length of the tubular element, wherein at least one fluid conduit of the several fluid conduits comprises a temperature control unit including a temperature sensor and a temperature influencer.

A manufacturing device for a filler element includes a sheet processing section forms a crimped part on a sheet and a feed portion that continuously feeds an additive dropwise onto an upper face of the sheet having the crimped part. The feed portion includes a multiple nozzle in which a large number of feed outlets feeding the additive are arranged in the width direction.

A smoking tip filter with a central channel infused with consumable flavorants, surrounded by non-infused paper layers. A barrier prevents diffusion beyond the channel. Inserting into a smoking device flavors smoke via central channel contact only, without burning additives. Enables enjoyable tailored flavors; avoids harsh tastes or paper contamination.

The present application relates to a lyocell material with a modified cross section, a cigarette filter including the lyocell material, and methods of manufacturing the lyocell material and the cigarette filter. The lyocell material and the cigarette filter including the same replace conventional cellulose acetate materials and filters, and provide excellent filter manufacturing processability and excellent cigarette properties (e.g., draw resistance) in addition to excellent biodegradability.

An aerosol-generating article (10)(100)(1000) comprises: an aerosol-generating substrate (12)(112)(1004); a downstream element (42)(150)(1008) provided downstream of the aerosol-generating substrate (12)(112)(1004) and in axial alignment with the aerosol-generating substrate, the downstream element comprising a cellulosic filtration material. The fibrous material comprises a plurality of regenerated cellulose fibres selected from one or more of viscose fibres, modal fibres, Lyocell fibres and viscose rayon fibres; or a plurality of natural fibres selected from one or more of flax fibres, hemp fibres, jute fibres, kenaf fibres, ramie fibres, abaca fibres, phormium fibres, sisal fibres, coir fibres, cotton fibres, and kapok fibres. The cellulosic fibrous material further comprises an additive coating applied to the plurality of regenerated cellulose or natural fibres, the additive coating comprising at least 5 percent by weight of exogenous lignin on a dry weight basis.

Filters and filter media are provided that comprise a paper substrate. Methods of making the filters and filter media, and products containing the filter, such as smoking articles and vaping articles, are also provided. The paper substrate comprises a monolayer base web having a first portion and a second portion. the first portion and the second portion are disposed adjacent each other along a thickness direction of the monolayer base web. The fibers of the first portion are intermeshed with the fibers of the second portion in a transition zone. The second portion may comprise more fibers, in terms of mass per unit area, than the first portion. the density of the paper substrate may be from about 200 mg/cm.sup.3 to about 300 mg/cm.sup.3.
