Rod making apparatus for smoking article manufacture
First Claim
1. An apparatus for manufacturing rods for use in the manufacture of smoking articles, the apparatus including:
- (a) means for providing a web of sheet-like material;
(b) means for pleating the web and providing a rod-like composite from the pleated web, such means including a frustoconical tube and a frustoconical member concentric to the tube and positioned with respect to the tube such that (i) an annular region is formed between the outer surface of the frustoconical member and the inner surface of the frustoconical tube, and (ii) the web is fed through the annular region; and
(c) means for receiving the rod-like composite and circumscribing the rod-like composite with wrapping material thereby forming a rod.

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.

12. An apparatus for manufacturing rods for use in the manufacture of smoking articles, the apparatus comprising:
-
(a) means for providing a first web of sheet-like material; (b) means for providing a second web of sheet-like material; (c) means for pleating the webs and providing a rod-like composite from the pleated webs, such means including; (i) a first frustoconical tube and a second frustoconical tube concentric to the first tube and positioned coaxially with respect to the first tube such that an annular region is formed between the outer surface of the second tube and the inner surface of the first tube, and (ii) a frustoconical member concentric to the second tube and positioned coaxially with respect to the second tube such that an annular region is formed between the outer surface of the frustoconical member and the inner surface of the second tube; and (d) means for receiving the rod-like composite and circumscribing the rod-like composite with wrapping material thereby forming a rod. - View Dependent Claims (13, 14, 15, 16)
