A method for making hinged-lid packets for smoking articles in a packing machine, comprising the steps of: - feeding groups of smoking articles into respective compartments of a first conveyor which moves with intermittent motion; - feeding sheets of wrapping material into contact with respective hollow mandrels carried by a second conveyor which moves with intermittent motion; - partly folding each sheet of wrapping material around the respective hollow mandrel along folding lines parallel to the direction of longitudinal extension of the selfsame hollow mandrel to form a partly finished container having four lateral panels reproducing the shape and size of corresponding lateral surfaces of the hollow mandrel and adhering to those lateral surfaces; - feeding blanks (S2, S3, S4, S5) of wrapping material into contact with respective sheets of wrapping material which are partly folded around the respective hollow mandrels, each blank (S2, S3, S4, S5) being shaped to obtain a hinged-lid packet and having four panels (1, 2, 3, 4) reproducing the shape and size of corresponding lateral panels of the sheet adjacent to it; - partly folding each blank (S2, S3, S4, S5) around the respective sheet of wrapping material along folding lines parallel to the direction of longitudinal extension of the hollow mandrel to form a partly finished packet having four lateral panels (1, 2, 3, 4) forming part of the selfsame blank (S2, S3, S4, S5) and respectively superposed on the four lateral panels of the container obtained from the sheet and reproducing the shape and size of those lateral panels; - transferring axially and in succession the groups of smoking articles from the compartments of the first conveyor into the respective hollow mandrels of the second conveyor; and - removing the partly finished packets in succession from the hollow mandrels and completing the folding of the respective sheet and of the respective blank (S2, S3, S4, S5); wherein, before removing each partly finished packet from the respective hollow mandrel, since each blank (S2, S3, S4, S5) has a portion able to form the hinged lid of the respective packet and protruding outside the selfsame hollow mandrel, there is a step of folding said portion of each blank (S2, S3, S4, S5), through folding means (44, 46, 47), forming the lid, characterized in that said four panels (1, 2, 3, 4) of the blank (S2, S3, S4, S5) extend side by side along a direction perpendicular to a direction of longitudinal extension of the packet obtainable from the blank (S2, S3, S4, S5), the blank (S2, S3, S4, S5) being foldable along folding lines made between the pairs of panels (1, 2, 3, 4) and parallel to said direction of longitudinal extension, in that the blank (S2, S3, S4, S5) has an outer and an inner flap (8, 7), rectangular in shape and extending respectively upwards and downwards from a rear panel of the panels (1, 2, 3, 4), and a further inner flap, rectangular in shape and extending downwards from a front panel of the panels (1, 2, 3, 4), in that an upper portion of the rear panel of the four panels (1, 2, 3, 4) is integral, on the outside of the selfsame four panels (1, 2, 3, 4), with a portion forming the hinged lid of the respective packet, the hinged lid being hinged to said rear panel about a weakened line, and in that the upper horizontal edge of the outer end flap of the rear panel, above the weakened line, is connected through a further weakened line to a rectangular panel, and the upper horizontal edge of the rectangular panel is connected, through a further weakened line, to a further rectangular panel which is equal in width to the rectangular panel but smaller in height. - feeding groups of smoking articles into respective compartments of a first conveyor which moves with intermittent motion; - feeding sheets of wrapping material into contact with respective hollow mandrels carried by a second conveyor which moves with intermittent motion; - partly folding each sheet of wrapping material around the respective hollow mandrel along folding lines parallel to the direction of longitudinal extension of the selfsame hollow mandrel to form a partly finished container having four lateral panels reproducing the shape and size of corresponding lateral surfaces of the hollow mandrel and adhering to those lateral surfaces; - feeding blanks (S2, S3, S4, S5) of wrapping material into contact with respective sheets of wrapping material which are partly folded around the respective hollow mandrels, each blank (S2, S3, S4, S5) being shaped to obtain a hinged-lid packet and having four panels (1, 2, 3, 4) reproducing the shape and size of corresponding lateral panels of the sheet adjacent to it; - partly folding each blank (S2, S3, S4, S5) around the respective sheet of wrapping material along folding lines parallel to the direction of longitudinal extension of the hollow mandrel to form a partly finished packet having four lateral panels (1, 2, 3, 4) forming part of the selfsame blank (S2, S3, S4, S5) and respectively superposed on the four lateral panels of the container obtained from the sheet and reproducing the shape and size of those lateral panels; - transferring axially and in succession the groups of smoking articles from the compartments of the first conveyor into the respective hollow mandrels of the second conveyor; and - removing the partly finished packets in succession from the hollow mandrels and completing the folding of the respective sheet and of the respective blank (S2, S3, S4, S5);
