Abstract

An aerosol-generating article according to various embodiments includes a first end face, a second end face opposite the first end face, a side face formed between the first and second end faces, a medium segment, a first segment, and a second segment, wherein the first segment is disposed on the downstream side of the medium segment, the second segment is disposed on the upstream side of the medium segment, the medium segment includes a cylindrical frame and a medium portion surrounding the outer surface of the frame, and the medium portion may be exposed to the outside through the side surface of the aerosol-generating article.

1 . An aerosol generating article comprising:
 a first end surface;   a second end surface on a side opposite to the first end surface;   a side surface formed between the first end surface and the second end surface;   a medium segment;   a first segment; and   a second segment,   wherein the first segment is disposed on a downstream side of the medium segment and the second segment is disposed on an upstream side of the medium segment, and   wherein the medium segment comprises a cylindrical frame, and a medium portion surrounding an outer surface of the frame, and the medium portion is exposed to outside through the side surface of the aerosol generating article.   
     
     
         2 . A device for manufacturing a medium segment included in the aerosol generating article of  claim 1 , the device comprising:
 a frame forming unit comprising a base substrate included in the frame, and a shaft that rotates such that the base substrate is wound obliquely, and configured to form the frame;   a medium coating unit configured to apply a medium to the frame formed in the frame forming unit;   an extrusion unit configured to compress the applied medium onto the frame;   a drying unit configured to dry the extruded medium; and   a cutting unit configured to cut the medium segment to a predetermined length.   
     
     
         3 . The device of  claim 2 , wherein the medium coating unit comprises:
 a container comprising the medium in a form of a slurry; and   a nozzle connected to the container to supply the medium to the frame.   
     
     
         4 . A method of manufacturing a medium segment of the aerosol generating article of  claim 1 , the method comprising:
 forming the frame;   applying a medium in a form of a slurry to the frame;   compressing and extracting the medium applied to the frame; and   drying the medium in the form of a slurry applied to the frame.   
     
     
         5 . The method of  claim 4 , wherein the forming of the frame comprises:
 supplying a base substrate obliquely to an axial direction of a shaft;   winding the base substrate around an outer surface of the shaft; and   adhering an overlapping region of the base substrate.   
     
     
         6 . The method of  claim 5 , wherein the base substrate is formed of at least one of paper, cellulose, or a combination thereof. 
     
     
         7 . The method of  claim 5 , wherein a shape of a cross section of the shaft perpendicular to a longitudinal direction of the shaft comprises at least one of a circle, triangle, rectangle, hexagon, octagon, or star shape. 
     
     
         8 . The method of  claim 4 , wherein the applying of the medium to the frame comprises:
 supplying the medium in the form of a slurry from a container to a nozzle; and   applying the medium to the frame from the nozzle.   
     
     
         9 . The method of  claim 4 , further comprising:
 cutting the medium segment to a predetermined length.
