An electronic cigarette cartridge suitable for electronic cigarettes includes an aerosol-forming substrate having a filler enclosed by a wrapping member on one end and a mouthpiece on the other end. The filler is a sheet-like member having an aerosol former. The sheet-like member is filled so as to form an air passage in the longitudinal direction of the electronic cigarette cartridge. The sheet-like member has cuts along the longitudinal direction of the electronic cigarette cartridge.

There is provided a method of making rods having predetermined values of cross-sectional porosity, and a cross-sectional porosity distribution value for use as an aerosol-forming substrate in a heated aerosol-generating article, including providing a continuous sheet of aerosol-forming material having a specified width and a specified thickness; gathering the sheet transversely relative to a longitudinal axis thereof; circumscribing the gathered sheet with a wrapper to form a continuous rod; severing the rod into a plurality of discrete rods; determining values of cross-sectional porosity and cross-sectional porosity distribution for at least one of the discrete rods; and controlling one or more manufacturing parameters to ensure that the cross-sectional porosity and cross-sectional porosity distribution values of subsequent rods are within the predetermined values.

A process of producing aerosol-generating material rod segments includes cutting a sheet of aerosol-generating material longitudinally to produce a plurality of aerosol-generating material strands; gathering the strands together to form an aerosol-generating material rod in which each of the plurality of aerosol-generating material strands is substantially non-coiled; and cutting the aerosol-generating material rod into segments to produce the aerosol-generating material rod segments. Also disclosed is an apparatus for producing aerosol-generating material rod segments, and a product including an aerosol-generating material rod.
