Abstract
The aerosol-generating article (1) comprises a tobacco element and a mouthpiece element. The tobacco element comprises an aerosol-forming substrate (2), a support element (3) arranged downstream of the aerosol-forming substrate (2) and an aerosol-cooling element (4) arranged downstream of the support element. The mouthpiece element comprises a filter segment (5) and a hollow tube (6). The aerosol-cooling element (4) has a length of at most 15 millimeter. A length of the mouthpiece element is adapted according to the length of the aerosol-cooling element (4) such that a total length of the aerosol-generating article (1) is kept at a predefined total length. The invention also relates to a method for manufacturing aerosol-generating articles.

Aerosol-generating article for use in electronic heating devices, the article comprising a tobacco element and a mouthpiece element, the mouthpiece element arranged downstream from the tobacco element,
- the tobacco element comprising an aerosol-forming substrate, a support element arranged downstream of the aerosol-forming substrate and an aerosol-cooling element formed of a gathered sheet and arranged downstream of the support element;
- the mouthpiece element comprising a filter segment and a hollow tube, wherein the hollow tube is a cardboard tube having a length between 3 millimeters and 8 millimeters and a wall thickness between 100 micrometers and 300 micrometers and arranged downstream of the filter segment and forming a most proximal segment of the aerosol-generating article;
- wherein the aerosol-cooling element of the tobacco element has a length of at most 15 millimeters, and
- wherein a length of the mouthpiece element is adapted according to the length of the aerosol-cooling element such that a total length of the aerosol-generating article is kept at a predefined total length of 45 millimeters.
Method for manufacturing aerosol-generating articles the method comprising the steps of:
- providing a semi-combined tobacco element by combining an aerosol-forming substrate, a support element and an aerosol-cooling element formed of a gathered sheet and arranged downstream of the support element and wrapping the aerosol-forming substrate, the support element and the aerosol-cooling element with a wrapper;
- providing a semi-combined mouthpiece comprising a filter element and a hollow tube, wherein the hollow tube is a cardboard tube having a length between 3 millimeters and 8 millimeters and a wall thickness between 100 micrometers and 300 micrometers;
- combining the semi-combined tobacco element and the semi-combined mouthpiece in an end-to-end relationship such that the aerosol-cooling element of the semi-combined tobacco element abuts the filter element of the semi-combined mouthpiece wherein the filter element forming a most proximal segment of the aerosol-generating article;
- wrapping the semi-combined mouthpiece and parts of the semi-combined tobacco element with a tipping material;
- and
- selecting a length of the aerosol-cooling element of at most 15 millimeters and
- adapting a length of the semi-combined mouthpiece such as to keeping a total length of the aerosol-generating article at a predefined value of 45 millimeters.
