<p>A packing method and machine (26) for producing a sealed package (3) containing a group (4) of cylindrical tobacco articles; a group (4) of tobacco articles is fed transversely along a packing path (P), i.e. with the longitudinal axes of the tobacco articles perpendicular to the packing path (P); a strip (33) of packing material is wound longitudinally, i.e. parallel to the packing path (P), about the packing path (P) to bring the two opposite edges of the strip (33) of packing material into contact and so form a tubular wrapping enclosing the group (4) of tobacco articles; the two opposite overlapping edges of the strip (33) of packing material are heat-sealed longitudinally, i.e. parallel to the packing path (P), to stabilize the tubular wrapping; and the tubular wrapping is heat-sealed and cut transversely, i.e. perpendicularly to the packing path (P), upstream and downstream from the group (4) of tobacco articles, to complete the sealed package (3).</p> |
