An aerosol-generating article (10) comprising an aerosol-forming substrate (11) and a wrapper (30) that circumscribes the aerosol-forming substrate. The wrapper defines an overlapping region (41) in which the wrapper overlaps itself, the overlapping region comprising a first section (42) and a second section (43) externally disposed on the first section. The second section comprises a fold (44) which defines a folded section (45) at one end of the wrapper, and the folded section is sandwiched between the first section and the second section. An outer adhesive is disposed between the folded section and the second section.

The present invention relates to a component (3) for a non-combustible aerosol provision article, and a method of forming the component. The component comprises: a core section (26) extending longitudinally: and an outer section (27) extending longitudinally comprising an aerosol-generating substrate which surrounds the core section and is configured to generate aerosol when heated. The core section comprises a first material configured to receive a heating element. The method comprises: providing an assembly comprising a sheet of aerosol-generating substrate and a first material: and arranging the sheet of aerosol-generating substrate and the first material into a component such that the sheet of aerosol generating substrate forms an outer section, which surrounds a core section formed by the first material.

An aerosol-generating article (10) comprising an aerosol-forming substrate (11) and a dual-layer wrapping structure (30). The dual-layer wrapping structure comprises an inner wrapper (31) that circumscribes the aerosol-forming substrate, the inner wrapper comprising an inner wrapper internal surface and an inner wrapper external surface opposite the inner wrapper internal surface. The dual-layer wrapping structure comprises an outer wrapper (32) that circumscribes the inner wrapper, the outer wrapper comprising an outer wrapper internal surface and an outer wrapper external surface opposite the outer wrapper internal surface. The outer wrapper internal surface and the inner wrapper external surface are attached to one another by means of a first adhesive (51). The dual-layer wrapping structure defines an overlapping region (41) in which the dual-layer wrapping structure overlaps itself, the overlapping region comprising a first section (42) and a second section (43) externally disposed on the first section, the first section and the second section being attached to one another by means of a second adhesive (52). The outer wrapper has a basis weight between about 10 grams per square metre and 28 grams per square metre.

An apparatus and method for forming a smoking article rod is provided. A forming device is configured to engage a continuous stream of a smokable filler material with a first surface of a longitudinally-continuous web of a wrapping material, the web having first and second edge portions extending along the web, and a second surface opposing the first surface. A wrapping device is configured to longitudinally overlap the first and second edge portions such that the first surface about the first edge portion extends over the second surface about the second edge portion, to contain the smokable filler material within the web. An adhesive applicator device is configured to apply an adhesive material to the second surface about and longitudinally along the second edge portion, between the overlapped edge portions, prior to the wrapping device engaging the overlapped edge portions, with the adhesive material therebetween, to form a sealed seam.
