A packaging machine has a wrapping device (5) for forming a tubular wrapping (6) from a continuous web of heat-seal material, and for feeding products (2) successively into the tubular wrapping (6); each product (2) being located between two free tubular portions (11) of the tubular wrapping (6), which are folded substantially onto the relative products (2), and are stabilized by means of at least two pairs of sealing devices (12,13) advanced along relative paths (P1,P2) independently. <IMAGE> |
