Abstract
Cigarettes are made by forming a basic filler stream comprising particles of tobacco or artificial tobacco or a combination of both, folding around the basic filler stream a web of reconstituted tobacco, and enclosing the resulting combination in a continuous paper wrapper to form a continuous cigarette rod which is then cut into predetermined lengths. The web may be continuous or may be in an expanded form as described in British Patent Specification No. 1531463.
