Method of folding a sheet of packing material with an extraction opening about a group of cigarettes, and corresponding package of cigarettes

摘要

A method of folding a sheet (22) of packing material, having an extraction opening (4), about a group (23) of cigarettes; the method includes the steps of: bringing a first end wall (26a) of the group (23) of cigarettes into contact with the flat sheet (22) of packing material, so that the major transverse edges (28) of the group (23) of cigarettes are parallel to the short sides of the sheet (22) of packing material, and the minor transverse edges (29) of the group (23) of cigarettes are parallel to the long sides of the sheet (22) of packing material; folding the sheet (22) of packing material into a U about the major transverse edges (28) of the first end wall (26a), so that the sheet (22) of packing material (22) covers both the major lateral walls (24) of the group (23) of cigarettes completely; folding the sheet (22) of packing material onto a second end wall (26b) of the group (23) of cigarettes; and folding the sheet (22) of packing material onto the minor lateral walls (25) of the group (23) of cigarettes; the first end wall (26a) of the group (23) of cigarettes is positioned asymmetrically with respect to the sheet (22) of packing material, so that the first end wall (26a) of the group (23) of cigarettes is closer to the short side of the sheet (22) of packing material opposite the extraction opening (4), and is further from the short side of the sheet (22) of packing material located close to the extraction opening (4).
