A feeding device (8, 8′, 8″, 8′″) for feeding a continuous strip (9) into a continuous fibrous band, in a tobacco industry machine for manufacturing rod-like elements, wherein the fibrous band is formed to a form of a continuous rod (CR) comprising the continuous strip (9) surrounded by the continuous fibrous band, the feeding device (8, 8′, 8″, 8′″) comprising: a strip supply unit (10) for feeding the continuous strip (9); a strip feeding unit (11) for feeding the continuous strip (9) into the middle of the continuous fibrous band; wherein the feeding device (8, 8′, 8″, 8′″) is configured such that the strip feeding unit (11) is located in the machine for manufacturing the rod-like elements between a fibrous band preparation unit (4) and a garniture unit (15) for forming the continuous rod. The feeding device (8, 8′, 8″, 8′″) further comprises: a feeding wheel (7), having a circumferential surface (20) comprising a cylindrical guiding surface (20A) for guiding the continuous strip (9); and guiding surfaces (21A; 22A; 31A; 32A; 41A; 42A; 51A; 52A). The guiding surfaces (21A; 22A; 31A; 32A; 41A; 42A; 51A; 52A) and the cylindrical guiding surface (20A) form a duct for guiding the continuous strip (9).

The present invention relates to a filter comprising a nonwoven substrate having a low density and comprising natural fibers and a binder. The filter can be used as a filter for a smoking or vaping article.

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 system and method for manufacturing a filter includes a filamentary material delivery apparatus, a support structure for supporting a continuous stream of filamentary material, and a particle distribution apparatus. The particle distribution apparatus includes an apertured distribution belt positioned above the support structure and in communication with an outlet of a particle storing hopper. The belt defines a plurality of spaced openings through which particles are distributed onto the continuous stream of filamentary material to form a particle-bearing stream of filamentary material.

A cooling filter rod and an application thereof are disclosed. The filter rod comprises a hollow tube (1). The inside of the hollow tube (1) is provided with at least one plate (2) which partition the inside of the hollow tube and is perpendicular to the axis of the hollow tube (1). The area of the plate (2) is the same as the cross-sectional area of a hollow portion of the hollow tube (1) Each plate (2) is independently provided with at least one through hole (3). The cooling filter rod reduces the adsorption of cigarette smoke, greatly lowers the smoke temperature felt by mouth, improves the sensory quality of cigarettes, and is suitable for application in new heat-not-burn cigarettes.
