Abstract: In a method of producing wrappings for smoking articles, the wrappings advance intermittently along a forming path with several stations, including a sealing station sealing the wrapping. Each wrapping continuously alternates a period of stop in a station with a period of movement between stations. A first predetermined stop time is associated with a first station, and a second predetermined stop time, greater than the first stop time, is associated with a second station, which is a sealing station. The second station has multiple positions for operating simultaneously on wrappings lots. Between stops in the first station, wrappings advance with a single step, with displacement that brings a wrapping to replace the immediately preceding wrapping. Between stops in the second station, wrappings advance with a multiple step, with a displacement that brings a wrappings lot to replace the immediately preceding lot in the positions of the second station.
