Abstract
In apparatus for producing two-piece foil wrappers for wrapping bundles of cigarettes, a web of foil is cut alternately by two cylindrical cutters operating against fixed blades. A suction roller receives each successive newly cut end of the foil before the next cutter operates. Each resulting pair of foil wrapper pieces is then transferred to a suction drum having a sector arcuately movable thereon to produce an overlap in the wrapper pieces.
