    • A method of making rods (2020) having predetermined values of cross-sectional porosity, and cross-sectional porosity distribution value for use as an aerosol-forming substrate in a heated aerosol-generating article(2000, 2001, 2002), comprises the steps of: providing a continuous sheet of aerosol-forming material (2) having a specified width and a specified thickness, gathering the continuous sheet of aerosol-forming material transversely relative to the longitudinal axis thereof, circumscribing the gathered continuous sheet of aerosol-forming material with a wrapper to form a continuous rod, severing the continuous 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. The predetermined value of cross-sectional porosity is preferably within the range 0.15 and 0.45 and the predetermined cross-sectional porosity distribution value is preferably within the range 0.04 and 0.22. The predetermined values can be selected to optimise aerosol deliverables for different types of heated aerosol generating articles.In preferred embodiments the continuous sheet may be crimped prior to being gathered.
    • 一种制造具有预定值的横截面孔隙率的棒(2020)和用于在加热气溶胶产生物品(2000,2001,2002)中作为气溶胶形成基质的截面孔隙度分布值)的方法包括以下步骤 提供具有特定宽度和特定厚度的连续片状气溶胶形成材料(2),其相对于其纵向轴线横向收集连续片状的气溶胶形成材料,将气溶胶形成材料的聚集的连续片材包围 用包装纸形成连续杆,将连续杆切割成多个分立的杆,确定至少一个离散杆的横截面孔隙率和横截面孔隙度分布的值,并将一个或多个制造参数控制到 确保后续棒的横截面孔隙率和横截面孔隙度分布值在预定值内。 截面孔隙率的预定值优选在0.15和0.45的范围内,并且预定的横截面孔分布值优选在0.04和0.22的范围内。 可以选择预定值以优化用于不同类型的加热烟雾发生制品的气溶胶递送物。在优选实施例中,连续片材可以在收集之前卷曲。
