  • Patent number: 6023911
    Abstract: A web of wrapping material for use in a cigarette packing machine is drawn off a roll and is advanced lengthwise, first by a single pneumatic belt conveyor which attracts an intermediate portion of the web, and thereupon by two additional pneumatic conveyors each of which attracts one of the two marginal portions of the web. The web is severed by a cross cutter between the first conveyor and the additional conveyors to yield a series of successive blanks, and such blanks are draped around successive arrays of unwrapped cigarettes or around successive cigarette packets which are advanced across the path for successive wrappers between the two additional conveyors.
