Abstract
In the production of filter cigarettes by a process in which the tobacco sections and filter portions are united while moving in an axial direction, the wrapper sections are resiliently pressed onto the abutting tobacco sections and filter portions, preferably by resilient pads. The pads are carried by a suction conveyor and their spacing may be adjusted by means for changing their timing or path length, to suit different lengths of tobacco sections and filter portions. The tobacco sections and filter portions may be assembled on a suction conveyor adapted to allow axial adjustment of the position of a conveyed article following slight lateral displacement of the article to reduce the suction grip of the conveyor.
