Method and apparatus for manufacturing coaxial cigarettes

摘要

A procedure for making coaxial cigarettes has an inner strand made and surrounded continuously with a sleeve strand (19,37). The inner strand and the sleeve strand are together surrounded by a sleeving material strip and from this coaxial cigarette strand with separating cuts executed in a cutting cycle, strand coaxial sections of single or multiple lengths are cut off one after another. At least in one of the strands (2), head reinforcements (68,69) are formed in the form of zones of higher strand thickness following one after another at regular distances.
