Abstract: A sub-unit of a smoking article includes a tubular wrapper which extends along a main axis of extension and internally defines a containment chamber containing a filling material of the tobacco industry. The tubular wrapper has an access opening on at least one of its ends for access to the containment chamber. The sub-unit also includes at least one closing element applied to the at least one end of the tubular wrapper to define a closing wall for closing the access opening. The closing element extends transversely to the main axis of extension in such a way as to at least partly close the access opening.

Abstract: A machine for making cigarette filters and which includes a forming beam having an internal channel whose transverse cross section changes shape along the main longitudinal direction of the channel. Porous conveyor means carry the tow along a feed path in the channel complying with the shape thereof and thereby being wrapped around the tow. At least one treatment station located along the feed path includes a nozzle for blowing a flow of steam into the channel. The nozzle includes a plurality of planar sectors positioned transversely to the channel and defining an overall planar flow orifice placed directly in communication with a steam feed duct. Each planar sector defines a respective planar flow orifice and at least two flow orifices have different thicknesses.
