ELEMENT PROVIDING PERMEABILITY FOR AEROSOL (VERSIONS) AND METHOD FOR ITS MANUFACTURE, AS WELL AS PRODUCT GENERATING AEROSOL AND METHOD FOR ITS MANUFACTURE Russian patent published in 2022 - IPC A24D3/04 

FIELD: aerosol devices.

SUBSTANCE: inventions group relates to an element providing aerosol permeability and a method for its manufacture, an aerosol generating product and a method for its manufacture. The aerosol-permeable element (1) comprises an aerosol-permeable core (11) surrounded by a sleeve (12). The sleeve (12) is formed from linear axially oriented fibers and the core (11) is formed from expanded randomly oriented fibers. The method includes forming two or more strips (2a, 2b) into segments surrounding the transmission path, bringing the segments together into a sleeve-forming device (7) to form the sleeve (12), and placing loose fibers (52) between the segments upstream of the generatrix. shape of the device sleeve (7) such that they are drawn into them in a random orientation and compressed between the segments as they are brought together to form a filter rod (8) with an aerosol-permeable core (11) inside the sleeve (12). The filter rod (8) is then cut to form an aerosol permeability element (1).

EFFECT: reduced stiffness of the sleeve and possibility of easy formation of the outer layer of the element providing aerosol permeability, with balanced indicators of effective filtration, minimum draw resistance, compressibility and wetting resistance.
