ABSTRACT:
On a cigarette packing machine, portions of wrapping material are formed from a strip travelling at a first constant speed, are accelerated on suction belts to a second speed, and are transferred by a suction roller into a position astride respective seats on a conveyor drum designed to step feed, to an unloading station, groups of cigarettes housed inside respective seats; the surface speed of the suction roller being so varied as to be maintained, at all times, greater than the travelling speed of the belts, and equal, for a given time period, to the surface speed of the conveyor drum.
