<p>A method of overwrapping packets (2) in the form of a rectangular prism, whereby a packet (2), as it is fed continuously along a wrapping path (P), is first centered with respect to a relative conveying seat (45), and is then paired with a relative sheet (13) of wrapping material, which is folded about the packet (2) to form a tubular wrapping (16) projecting axially from the packet (2) in the form of two tubular appendixes (19), which are folded to form a closed overwrapping (107); each tubular appendix (19) being at least partly folded onto the relative packet (2) before the relative tubular wrapping (16) is completed. <IMAGE></p> |
