Claim:
Method for the production of filter-tipped cigarettes ( 25 ) from tobacco rods ( 15 ), which are severed centrally to produce part-rods ( 16 , 17 ), the part-rod ( 16 , 17 ) being moved apart, and being connected by means of wrapping paper ( 22 ) to a filter piece ( 21 ) and cigarette units ( 23 ) thus formed being severed centrally in the region of the filter piece ( 21 ), characterized by the following features: a) the tobacco rods ( 15 ) or the part-rods ( 16 , 17 ) are fed to a central main cylinder ( 10 ) and transported by the latter, b) the part-rods ( 16 , 17 ) are moved to a distance apart from one another by axial displacement during transportation on the main cylinder ( 10 ), c) filter pieces ( 21 ) are fed to the main cylinder ( 10 ) by a filter cylinder ( 2 ) disposed adjacently to the main cylinder ( 10 ) and are inserted into a gap formed between the part-rods ( 16 , 17 ), d) the two mutually assigned part-rods ( 16 , 17 ), each with one filter piece ( 21 ), are removed from the main cylinder ( 10 ) and transported outside he region there of, during which they are joined together and connected to one another by means of wrapping paper, e) cigarette units ( 23 ) thus formed are returned to the main cylinder ( 10 ) and, during further transportation on the main cylinder ( 10 ), are severed centrally in the region of the filter piece ( 21 ), and f) the filter-tipped cigarettes ( 25 ) thus formed are displaced in the longitudinal direction during the further transportation by the main cylinder ( 10 ), a distance being formed between them, and are then removed from the main cylinder.
