• the tobacco material comprises reconstituted tobacco.
• the layer of tobacco material has a rough surface.
• the layer of tobacco material may be described as having an uneven or irregular surface.
• the rough surface may be formed when preparing the layer of tobacco material. For example, pressing the layer of tobacco material either longitudinally or laterally may provide a rough surface.
• strands of tobacco material may be laid onto the paper and compressed, forming an irregular surface.
• the rough surface may be created by the presence of a fibrous material.
• larger particles or fibres maybe distributed either uniformly or randomly across the surface of the layer of tobacco material to provide a rough surface comprising a series of channels or pathways within the tobacco material through which air may pass. These pathways may be within the layer of tobacco material or they may be formed between the surface of the tobacco layer and an adjacent layer when rolled or folded.
• relatively larger particles of fibres may be present within the layer of tobacco material. Their greater size prevents the tobacco material from forming a smooth surface and therefore creates a rough surface.
• the fibrous material may be from a cellulosic source, such as tobacco, reconstituted tobacco (including, for example, so called Fibex), wood or paper, waste lamina, or other sheet material such as smokeable filler material comprising a blend of non-combustible inorganic filler material, a binder, and an aerosol generating means.
