Abstract: Provided herein is an aerosol-generating article with enhanced vapor production. The aerosol-generating article according to some embodiments of the present disclosure includes a medium portion, a support structure which is disposed downstream of the medium portion and includes a first tubular structure having a first hollow formed therein, a cooling structure which is disposed downstream of the support structure and includes a second tubular structure having a second hollow formed therein, and a mouthpiece portion which is disposed downstream of the cooling structure. Here, an upstream end of the second tubular structure may abut a downstream end of the first tubular structure, and an average cross-sectional area of the second hollow may be larger than an average cross-sectional area of the first hollow. The cross-sectional area difference enhances an air flow diffusion effect, thereby eventually improving vapor production of the aerosol-generating article.

Abstract: Disclosed is an aerosol-generating rod, in which a medium portion includes a plurality of strands, the medium portion and a filter portion are connected in a longitudinal direction of the aerosol-generating rod, and the plurality of strands are arranged parallel to each other in the longitudinal direction.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for manufacturing an aerosol-forming rod, and according to the present disclosure, it is possible to realize various aerosol-forming product properties, by utilizing the sheet-specific characteristics of each manufacturing process of reconstituted tobacco sheets and mixing two or more types of reconstituted tobacco sheets having different types, different physical properties, or different main components to control the physical properties and taste of the tobacco rod.
