1. A method for making a sub-unit of a smoking article, comprising the steps of:
preparing a tubular segment of the tobacco industry, the tubular segment being internally provided with a through duct terminating with end openings of the tubular segment;
applying a closing element internally or externally on an application end of the tubular segment to form a closing wall to at least partly close the application end;
performing the step of applying the closing element with an applicator moving with translational to-and-fro motion along an application direction parallel to an axis of predominant extension of the tubular segments of the succession of tubular segments.
