Embodiment Construction

[0061] reference now Figure 1 to Figure 3 , shows an aerosol permeating element 1 according to an embodiment of the present invention, which is a filter portion 1 for an aerosol-generating article (shown in outline). The filter portion 1 in this embodiment comprises an aerosol permeable core 2 of extruded polymeric filter material surrounded by a sleeve 3 of linear, axially oriented fibers. The core 2 has a plurality of paths 21 depicted therein extending along its axial length. The core 2 is formed of polylactic acid (PLA) material in this embodiment and has a diameter D of 5 mm. In this embodiment, the sleeve 3 has a wall thickness W of 1 mm.

[0062] Figure 4 shows something like Figure 1 to Figure 3 The filter section 1', wherein like reference numerals denote like features. The filter portion 1' according to this embodiment is Figure 1 to Figure 3 The difference is that a plurality of channels 22 are described along the outer surface of the core 2'. The channel...

Abstract

The present invention discloses a filter part (1, 1') for use in an aerosol-generating article and a method of manufacturing the filter part (1, 1'). The filter portion (1, 1') comprises an aerosol permeable core extrusion (2) surrounded by a sleeve (3) formed of predominantly linear, axially oriented fibers. The method includes: forming two or more strips (4a, 4b) into segments around a conveying path; bringing the segments together into a sleeve former (7) to form a sleeve (3); An aerosol permeable core extrusion (80) is introduced between the segments upstream of the former (7) and the segments are joined together to form a sleeve around the core extrusion (80), thereby forming a filter rod (9) ). The filter rod (9) is then cut to form filter sections (1, 1').

Description

technical field [0001] The present invention generally relates to aerosol-generating articles. More specifically, but not exclusively, the present invention relates to aerosol permeable elements for use in tubular aerosol-generating articles, said aerosol-generating articles including, in particular, such aerosol-generating substrates configured to heat aerosol-forming substrates without burning them product. The present invention also relates to methods of making such articles and components. Background technique [0002] The filter portion or cooling portion of an aerosol-generating article performs a variety of functions and, as such, several properties must be considered in its design and manufacture. The primary role of the filter section is filtration or cooling efficiency, i.e. its effectiveness in preventing unwanted components of the aerosol from reaching the user, but this must always be correlated with the overall suction resistance (i.e., when the aerosol passe...
