    Abstract: A machine for making sub-units of smoking articles includes a conveyor, a feed unit and an applicator. The conveyor conveys a succession of tubular segments transversely along a conveying direction. The feed unit feeds and conveys a continuous web and advances the web along a feed direction parallel to the conveying direction of the tubular segments so that the web faces respective application ends of the tubular segments. The applicator is movable along an application direction parallel to an axis of predominant extension of the succession of tubular segments and is configured to engage the web so as to separate respective closing elements from it. The applicator is also configured to apply the closing element internally or externally on an application end of a respective tubular segment in such a way as to form a closing wall to at least partly close the application end.

    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.
