Problems solved by technology

[0007] However, when thermally conductive patches are cut from a foil web and applied at high speeds, it can be difficult to precisely position the patch on the web, especially when proper positioning of the patch requires precise control of the relative speed of the two webs Time
Additionally, individual patches of thermally conductive material can fall off the cutting or transfer rolls before they are applied to the web, causing machine interruptions

Embodiment Construction

[0137] figure 1 A first example of a smoking article comprising a heat conducting element made according to the invention is shown. The smoking article 101 comprises a combustible carbonaceous heat source 103 , an aerosol-forming substrate 105 , an elongated expansion chamber 107 and a mouthpiece 109 aligned contiguously on one axis. The combustible heat source 103, aerosol-forming substrate 105, elongate expansion chamber 107 and mouthpiece 109 are overwrapped in an outer paper wrapper 111 of low-air permeability cigarette paper. Such as figure 1 As shown, a non-combustible, gas-resistant first barrier coating 113 is provided over substantially the entire rear surface of the combustible carbonaceous heat source 103 . In an alternative embodiment, a non-combustible, substantially gas-impermeable first barrier layer is provided in the form of a disc adjacent to the rear surface of the combustible carbonaceous heat source 103 and the front surface of the aerosol-forming substr...

Abstract

There is provided a smoking article (101) comprising a carbonaceous combustible heat source (103), an aerosol-forming substrate (105) and a wrapper (111) circumscribing at least the heat source (103) and the aerosol-forming substrate (105). One or more heat conducting elements (119) overlie a rear portion of the heat source (103) and an adjacent front portion of the aerosol-forming substrate (105). At least one heat conducting element (119) comprises a patch of thermally conductive printable medium printed onto the wrapper (111). Also provided is a method for applying heat conducting patches (303) onto a web of smoking article wrapper material (305), wherein at least some of the patches (303) comprise an area of thermally conductive printable medium.

Description

technical field [0001] The invention relates to a method of applying a thermally conductive patch to a web of material. More specifically, the present invention relates to a method of applying a thermally conductive patch to a web of smoking article wrapper. The invention also relates to a method of manufacturing a multi-segment assembly for a smoking article and a smoking article having one or more thermally conductive elements. Background technique [0002] Various smoking articles have been proposed in the art in which the tobacco is heated rather than combusted. One purpose of such 'heated' smoking articles is to reduce known harmful smoke constituents of the type produced by the combustion and thermal degradation of tobacco in conventional cigarettes. In one known type of heated smoking article, an aerosol is generated by transferring heat from a combustible heat source to a physically separated aerosol-forming substrate, such as tobacco. The aerosol-forming substrat...
