ABSTRACT:
A rod of smoking material, for use as a smoking article or a part thereof is formed by a multiplicity of laminiform self-sustaining smoking-material elements, for example discs, extending transversely of the rod and located in face-to-face contact with one another. The thickness of the elements, which may be up to 2.5 mm, is suitably within a range of 0.1 to 0.8 mm. It may vary within the rod or from element to element along the rod. The material of the elements may have inherent smoke-permeability sufficient to afford an acceptable pressure drop through the rod or the elements may be formed or provided with smoke passages therethrough, with either the same relative distribution of passages from one element to the next or with adjacent elements so oriented in relation to each other as to provide smoke passages of predetermined form through the rod. The smoking material of the elements preferably extends over an area less than the cross-sectional area of the rod, suitably over 10 to 40% of that area. One or more additives may be applied to some or all of the elements either uniformly or in selected parts thereof. The elements may be secured together by adhesive and or by being enclosed in a wrapper. The elements may be formed with protrusions from or undulations of faces thereof.
