Abstract

Apparatus for increasing the distance between successive pairs of coaxial plain or filter cigarettes has a first rotary conveyor with axially parallel peripheral flutes which deliver pairs of cigarettes to a transfer station, a second rotary conveyor which receives one cigarette of each pair from the first conveyor by way of a third rotary conveyor and which receives the other cigarette of each pair from a delivering unit positioned to simultaneously move each other cigarette axially of and away from the one cigarette. The delivery unit has two parallel discs which are coupled to each other by cranks having pins provided with flutes for the transfer of other cigarettes from the first conveyor to the second conveyor. The discs rotate about a common axis or about parallel axes inclined relative to the axes of rotation of the first, second and third conveyors. One of the discs receives torque from a gear, a gear transmission or a cardan joint, and the other disc receives torque from the one disc through the cranks.
