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.

A filter for a smoking article has improved biodegradability and improved taste during smoking of the smoking article. The filter includes a segment having a filtration substrate including natural cellulose fibres, and a wrapper at least partly surrounding the segment. The filtration substrate contains a composition including an additive for reducing phenols.

A system includes system at least one dispenser configured to dispense to dispense a plurality of segments on a first conveying path and a spacing drum configured to receive a number of the plurality of segments per revolution of the drum and configured to release the number of segments on a second conveying path at a segment-release spacing and a segment-release speed along the conveying path, the number of the plurality of segments being at least three and the number of segments released by the spacing drum forming a filter element.

The object of the application is an apparatus for processing rod-like articles of the tobacco industry wherein the rod-like articles are conveyed in flutes of a conveyor along a path of movement transverse to the axis of the rod-like article with a pair (6) of circular knives (6A, 6B) adjacent to each other, whereas the axes of rotation (Z, Z′) of the circular knives are situated on two sides of the path of movement (P), characterized in that the path of movement (P) passes through an area (6C) of overlapping of the adjacent circular knives (6A, 6B), whereas in the pair (6) of the adjacent circular knives (6A, 6B) one circular knife (6A) is situated above the carrier surface (2A, 2A′) of the conveyor (2, 2′), whereas the other circular knife (6B) is situated beneath the carrier surface (2A, 2A′) of the conveyor (2, 2′). The object of the application is also a method for processing rod-like articles (1) of the tobacco industry.

A process for producing a filter element suitable for use in smoking articles may include: embedding a bundle of cellulose acetate fibers with an aqueous suspension of polyhydroxyalkanoate (PHA) to obtain a wet bundle of the cellulose acetate fibers covered by the aqueous suspension of the PHA; shaping the wet bundle in a form of a continuous elongated element; heating the continuous elongated element to temperature greater than or equal to 140° C. and less than or equal to 180° C. for time sufficient to melt the PHA and to evaporate water from the continuous elongated element; cooling the heated continuous elongated element to obtain crystallization of the PHA; and cutting the so-obtained continuous elongated element into segments of predetermined length.

A method for producing filters for smoking articles includes: providing a filter rod, the filter rod having a cylinder shape with a first filter rod end, a second filter rod end and a circumferential filter rod surface; providing an outer wrapper; wrapping the outer wrapper around the filter rod along a filter rod circumferential direction covering at least parts of the circumferential filter rod surface; obtaining a wrapped filter rod; cutting the wrapped filter rod perpendicular to a filter rod longitudinal direction into outer and inner wrapped filter rod segments, wherein first and second outer wrapped filter rod segments include the first and second filter rod ends, respectively, and have a length being less than 10% of a total length of the filter rod and/or less than 10 mm; and obtaining the inner wrapped filter rod segments as the filters and disposing the outer wrapped filter rod segments.

The invention provides a material which comprises a paper substrate and a nonwoven substrate having a low density which can be used as filter for a smoking or vaping article.

The object of the application is an apparatus for the manufacturing of multi-segment rods, comprising a feeder (2) delivering rod-like elements (S1, S2) in the form of a rod-like elements train (ST1); a wrapping device (6) situated downstream of the feeder (2) in the direction of movement of the elements train (ST1), for wrapping the rod-like elements train (ST1) into the wrapping material (7) thereby forming a continuous rod (CR); a conveying unit (1) disposed between the feeder (2) and the wrapping device (6) for the formation of the train (ST2) of axially positioned rod-like elements (S1, S2) and for transferring rod-like elements (S1, S2) by means of a number of conveying wheels (9, 10, 11) to the wrapping device (6), whereas the rod-like elements are moved along guides (20, 21, 22); as well as cutting means (8) used for cutting the continuous rod (CR) into rods (R), each containing a set of rod-like elements (S1, S2), wherein at least the last of the wheels (11) in the unit (1) conveying the rod-like elements (S1, S2) to the wrapping device (6) is a wheel whose circumferential surface (11A) has no lugs.

The present invention relates to an article (10). The article comprises an aerosol-generating substrate (12) and a region (14) positioned longitudinally relative to the aerosol generating substrate. The region comprises a rod segment (16) formed from a plurality of elongate strips (17) of sheet material (18) extending longitudinally through said rod segment. The present invention also relates to a segment of sheet material for a rod segment. The segment of sheet material comprises a segment of a web (44) of sheet material (18) of discrete length comprising a plurality of elongate strips (17) and a band (22) of sheet material extending transversely to the plurality of elongate strips. The plurality of elongate strips extend from the band of sheet material. The present invention also relates to an apparatus (40) for manufacturing rod segments and a method of forming a rod segment.

The object of the application is a cleaning system of a drum conveyor of a filter segment feeding apparatus in the tobacco industry wherein a transport drum (3) comprises a plurality of discs (4) on the circumferential surface of which concavities (5) are formed whereas the concavities of the individual discs are positioned relative to one another so that together they form channels (6) receiving filter rods (1), where in the said channels (6) the filter rods (1) are transported during cutting, whereas the borders of adjacent discs (4) do not contact one another and in this way they form circumferential grooves (9). The discs (4) have passages (12) discharging the dirt, the circumferential grooves (9) have a connection with the passages (12) discharging the dirt, and the system comprises a vacuum channel (15) receiving the dirt having a connection with the passages (12) discharging the dirt in the discs (4).
