ABSTRACT:
Rods for use in the manufacture of smoking products are provided using a rod making apparatus equipped with a web preforming unit. A web of sheet-like material is passed through the web preforming unit and is pleated to form a rod-like composite. The rod-like composite then is circumscribed with wrapping material to provide a rod. The web preforming unit includes an outer frustoconical tube and an inner frustoconical member. The frustoconical member is concentric to the tube, and is positioned coaxially with respect to the tube such that an annular region is formed between the outer surface of the member and the inner surface of the tube.
