Method for assembling a cartridge for a smoking article

A method for assembling a cartridge for an aerosol delivery device, the method comprising:

• wrapping a reservoir substrate at least partially about an atomizer;
• providing an outer body configured to at least partially receive the reservoir substrate and the atomizer therein;
• and inserting the reservoir substrate and the atomizer through a tool into the outer body, the tool defining a funnel portion configured to reduce an outer dimension of the reservoir substrate such that the outer dimension of the reservoir substrate is less than or equal to an internal dimension of the outer body to facilitate insertion of the reservoir substrate into the outer body;
• the method further comprising engaging the reservoir substrate with one or more fingers such that the reservoir substrate remains at least partially wrapped about the atomizer when beginning to insert the reservoir substrate through the tool into the outer body;
• and
• releasing the one or more fingers from the reservoir substrate when the reservoir substrate is inserted to a predetermined depth in the tool, wherein releasing the one or more fingers comprises deflecting the one or more fingers away from the reservoir substrate by contacting the one or more fingers with the tool.
