Abstract
The spacing of cigarettes which are moved sideways in the flutes of two driven drum-shaped conveyors is changed during transfer of successive cigarettes from one of the conveyors whose flutes are spaced apart by a greater distance onto the other conveyor whose flutes are spaced apart by a lesser distance, or vice versa. The speed ratio of the conveyors is proportional to the ratio of the two distances and the configuration of flutes is such that they can bypass each other during travel past a transfer station at which successive flutes of the one conveyor are in temporary register with successive flutes of the other conveyor. The transfer takes place by suction, and the cigarettes are held by suction in those flutes which transport them toward the transfer station as well as in the flutes which transport them away from the transfer station.
