Apparatus for altering the spacing between pairs of coaxial rod-shaped articles of the tobacco processing industry
First Claim
1. Apparatus for changing the distance between successive sets of coaxial rod-shaped articles of the tobacco processing industry which are supplied as rows of parallel articles and wherein each set includes a first article forming part of one of the rows and a second article forming part of another row, comprising a first conveyor having means for transporting successive sets of articles to a transfer station;
- a second conveyor having means for receiving successive sets of articles at the transfer station, said first and second conveyors being rotatable about first and second axes, respectively; and
means for delivering the first articles of successive sets from the transporting means of the first conveyor to the receiving means of the second conveyor with simultaneous shifting of the first articles axially relative to the respective second articles, including first and second motion transmitting members rotatable about additional axes which are inclined relative to said first and second axes, means for rotating said members, and means for coupling said members including article transferring elements.

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.
