A cigarette-rolling kit system and method for forming a cigarette with shredded leaf enclosed in rolling paper, providing a forming block having a major-arcuate trough and a semicircular trough, a pushing tab, a leveling slider, a tamping cylinder, and a leaf shreds preparation tool, where the major-arcuate trough retains the forming cigarette and guides the initial rolling, and the semicircular trough guides the final rolling.

A cigarette is provided with the tobacco column portion adjacent the filter assembly encased by a heat shrink material whereby as the burn approaches the butt the heat shrink material begins to contract radially and compress the encased tobacco column restricting the air flow therethrough. This reduces the diameter of burning column adjacent the filter assembly and thus extinguishes or at least confines the remaining tobacco in the cigarette.

A method for making smokers' articles by subdividing a semifinished item which includes least five sticks aligned with each other along a main axis, at least two of the sticks are of a type different from the others; the method includes a step of forming the semifinished item by aligning the five sticks in a predetermined succession along the main axis and a step of subdividing a single rod into at least three sticks, followed by a step of aligning along the main axis each of the three sticks obtained from the rod alternating them with each of the sticks of different type, so as to form the semifinished item.

The method and apparatus for manufacturing aerosol-generating semi-finished products comprise the steps of combining substantially cylindrical segments along a longitudinal first motion path. The following steps are performed along the first motion path: feeding a stream of at least three different segments along the first motion path, thereby arranging the at least three segments in alternating order, wrapping the stream of at least three segments in a sheet material to form an endless rod of segments, and cutting the endless rod of segments, thereby separating the endless rod of segments into wrapped segment rods. The method also comprises the step of processing wrapped segment rods along a second motion path, wherein the following step is performed along the second motion path: receiving the wrapped segment rods in flutes of a fluted receiving drum, wherein an end of the first motion path is aligned with a longitudinal axis of the flutes of the fluted receiving drum.

The invention relates to a cylindrical rod (10) for aerosol-generating articles comprising a rod component (12) being circumscribed by a wrapper (14). The wrapper comprises laterally opposed edge portions which overlap so as to form an overlapping zone (16). Glue (24) is applied to the overlapping edge portions of the wrapper, by which the overlapping edge portions are adhered to each other. The glue is applied in such way, so as to form one or more glue zones (22) within the overlapping zone. The wrapper further comprises a plurality of cavities (26), wherein at least a part of the cavities is provided in the one or more glue zones. The invention further relates to a method for preparing a cylindrical rod for aerosol-generating articles.

A plant material assembly for separating cannabis plant material is provided having a plant material hopper configured to receive the cannabis plant material and feed the cannabis plant material to a plant material separator. The plant material separator is configured to separate undesirable plant material from desirable plant material by using a first roller, a second roller, and a third roller. The first roller and the second roller separating the cannabis plant material into the desirable plant material and the undesirable plant material by sending the desirable plant material in a first directional path and the undesirable plant material in a second directional path. Next, the third roller is used in relation to the first roller and the second roller, wherein the third roller redirects the undesirable plant material from the second directional path into a third directional path and finally into a catch depository.

A smoking article includes a contoured filter element having a cylindrical rod end portion and a cylindrical mouth end portion and a contoured portion between the cylindrical rod end portion and the cylindrical mouth end portion. The contoured portion defines an exterior surface of the smoking article and having a first cross-sectional area that is less than a cross-sectional area of either the cylindrical rod end portion or the cylindrical mouth end portion.
