The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.

The method for manufacturing a wrapped endless rod of substantially flat continuous material comprises the steps of providing a substantially flat continuous material, treating the substantially flat continuous material with corona discharge and forming the corona treated substantially flat continuous material into an endless rod. Further steps comprise providing a wrapper, applying adhesive to the wrapper and wrapping the endless rod with the wrapper. Therein the step of applying adhesive to the wrapper comprises applying adhesive over a width of the wrapper and in a central portion of the wrapper.

A filter (11) for a smoking article (10) comprises a first flow path (13) through the filter, a second flow path (14) through the filter, the second flow path being disposed around the first flow path, and a selector (16) for allowing flow selectively through the first and second flow paths.

An apparatus for manufacturing of rods of a continuous material strand comprising a feeding unit for feeding material strand, a guiding unit for guiding material strand, a compressing unit for compressing the strand and forming a continuous rod of the material strand, and an object feeding unit for feeding an object to the compressing unit. The apparatus is characterised by being provided with a cutting unit for lengthwise cutting of the material strand into at least two partial strands, whereas the partial strands are fed through the guiding unit to the compressing unit. It is provided with a system for adjusting the position of at least one cutting element in the cutting unit so as to adjust the widths of the partial strands thus determining the point of insertion of the object being inserted.

A device for manufacturing multi-segment rod-like articles (R), the device comprising: a feeding unit (5) for feeding a train of segments (S1, S2, S3), the feeding unit (5) comprising a feeding wheel (8), a transporter (9) for transporting a wrapper (10) having a form of a tape and the segments (S1, S2, S3) on the belt (13) along a guide (14) provided with an inlet part (14-I), a forming unit (11) for forming a continuous rod (CR) from the segments (S1, S2, S3), a cutting head (12) for cutting the continuous rod (CR) into individual multi-segment rod-like articles (R), wherein the feeding wheel (8) is located above the inlet part (14-I) of the guide (14). At least one rotary pressing element (21, 23, 27, 32) having a peripheral pressing surface (22, 24, 30, 31, 35, 36) is positioned above the inlet part (14-I) of the guide (14) and before the forming unit (11), downstream the feeding wheel (8) in a direction of movement of the belt (13), the rotary pressing element (21, 23, 27, 32) being configured to adjust axial alignment of segments (S1, S2, S3).

Various structures for interfaces for a smokable element to connect to a smoke and/or tar filter, and related methods, are provided. For example, the structures and methods enable repeatably and securely connecting or interfacing a smokable element, e.g., an herbal joint, to an air filter, e.g., a smoke and/or tar filter. For instance, an interface can have a horn-shaped end with a deformable opening that receives a smokable element, creating at least a partial seal between the deformable opening of the horn-shaped end and the smokable element. Also, the other end of the interface can have a round end that attaches to an air filter.
