Embodiment Construction

[0089] figure 1 It is a perspective view of a smoking article 100 including a filter manufactured according to an embodiment of the present invention. The smoking article 100 includes a tobacco rod 101 having a substantially cylindrical shape and a filter 103 having a substantially cylindrical shape. The tobacco rod 101 and the filter 103 are arranged axially in an end to end relationship, preferably adjacent to each other. The tobacco rod includes an outer packaging material 105 surrounding the smoking material. The external packaging material 105 may be a porous packaging material or a paper packaging material. The tobacco is preferably shredded tobacco or formula shredded tobacco. The tobacco rod 101 has an upstream ignition end 107 and a downstream end 109. The filter 103 has an upstream end 111 and a downstream mouth end 113. The upstream end 111 of the filter 103 is adjacent to the downstream end 109 of the tobacco rod 101. Even though figure 1 The middle is not visi...

Abstract

A method and apparatus for manufacturing filters for smoking articles is provided. The method includes providing a hollow tube (309) made of filter material. Each hollow tube has an outer diameter and an inner diameter. The method also includes providing a filter insert (205). Each filter insert (205) has a first portion having a cross-sectional dimension greater than the inner diameter of the hollow tube. The method also includes inserting each filter insert (205) into a hollow tube (309) made of filter material. During insertion, the first portion of the filter insert (205) engages the hollow tube (309) to retain the filter insert in the hollow tube.

Description

Technical field [0001] The invention relates to a method and apparatus for manufacturing a filter for smoking articles. Background technique [0002] Combustible smoking articles such as cigarettes generally include shredded tobacco (usually in the form of formulated shredded tobacco) surrounded by a paper wrapper forming the tobacco rod. Cigarettes are used by consumers by lighting one end and burning the tobacco rod. The consumer then receives mainstream smoke by smoking on the opposite end (mouth end or filter end) of the cigarette. The shredded tobacco may include one type of tobacco or a mixture of two or more types of tobacco. [0003] Various smoking articles in which a smoke-forming substrate such as tobacco is heated instead of being burned have also been proposed in the prior art. In heated smoking articles, smoke is generated by heating the aerosol-forming substrate. Known heated smoking articles include, for example, smoking articles in which smoke is generated by e...
