Abstract (en)

Wrapping method and packer machine (15) to fold a sheet (11) of wrapping material around a group (2) of tobacco articles; the sheet (11) of wrapping material is caused to rest against an upper wall (3) of the group (2) of tobacco articles; the sheet (11) of wrapping material is "U"-folded around the group (2) of tobacco articles so that the "U"-folded sheet (11) of wrapping material has two ends (13, 14) that protrude from the larger side walls (5, 6) of the group (2) of tobacco articles; the two ends (13, 14) are overlapped to one another, thus giving to the sheet (11) of wrapping material a tubular shape; and the overlapping portions of the two ends (13, 14) of the sheet (11) of wrapping material are heat-sealed so as to stabilize the tubular shape of the sheet (11) of wrapping material and form a sealing fin (F); the two ends (13, 14) are overlapped and heat-sealed to one another while the group (2) of tobacco articles coupled to the sheet (11) of wrapping material is housed in a pocket of a wrapping conveyor (21), which is fed along a wrapping path (P2); and the pocket of the wrapping conveyor (21) is oriented so that the sealing fin, i.e. the overlapping portions of the two ends of the sheet (11) of wrapping material, is arranged parallel to the wrapping path (P2) at least until the heat-sealing process has ended.
