A method of producing a sealed wrapping (2) about a group (3) of cigarettes (4), whereby a sheet (1) of wrapping material is folded into a U about the group (3), is closed into a tube by gripping and sealing a first pair of flaps (9), and is sealed by closing the ends of the tube by gripping and sealing relative second pairs of flaps (18); the sealing of each second pair forms a relative wall (7; 6) of the sealed wrapping (2), a relative tab (25; 15) crosswise to the wall (7; 6), and a relative pair of triangular tabs (24), which, after the tab (25; 15) is folded onto the respective wall (7; 6), are folded onto an adjacent relative axial end wall (7) of the sealed wrapping (2).
