The first conveyor which moves the single file of cigarettes upwardly uses an endless belt made of a flexible material with apertures spaced along the path thereof and an evacuation chamber over which the belt slides. The belt serves to cover over the evacuation chamber while the suction force created within the chamber draws air through the apertures in the belt to hold a cigarette thereon. Each cigarette which is positively held on the belt under suction serves to hold a number of cigarettes in front on the conveyor belt.
