<p>A folding method for forming a sealed tubular wrapping about a packet (2), whereby the packet (2) is fed onto a step-operated folding conveyor (7) together with a sheet (3) of wrapping material having a first and a second end portion (22, 21); the sheet (3) is folded into a tube about the packet (2) so that the first end portion (22) is superimposed on the second end portion (21) along one of the surfaces (4; 5) of the packet (2); and the first end portion (22) is then detached from the second end portion (21) to deposit adhesive between the first (22) and second (21) end portions, and is then brought back into contact with the second end portion (21). <IMAGE></p> |
