Packaging machine for generating re-closable packages

A packaging machine for generating a re-closable package, the packaging machine comprising:

• a forming tube configured to receive a film having first and second longitudinal ends and to impart a tubular shape to the film, the forming tube including a first area and a second area, the first area being configured to receive the film and to impart the tubular shape to the film such that the film surrounds the second area and the first and second longitudinal ends of the film are located facing one another;
• a guiding device arranged upstream of the second area of the forming tube in the forward movement direction and configured to receive a re-closable strip only and redirecting the re-closable strip in the forward movement direction such that the re-closable strip is housed between the facing first and second longitudinal ends of the film;
• a longitudinal sealing tool configured to seal the first and second longitudinal ends of the film and the re-closable strip to one another such that a film tube is produced;
• a driving module arranged facing the second area of the forming tube and configured to move the film tube, and/or the film with a tubular shape, in a forward movement direction at a first forward movement speed;
• a first driving assembly arranged facing the forming tube and arranged downstream the longitudinal sealing tool in the forward movement direction, the first driving assembly configured to move the film tube in the forward movement direction at a second forward movement speed while acting on the first and second longitudinal ends of the film previously sealed to the re-closable strip;
• a second driving assembly located upstream of the longitudinal sealing tool in the forward movement direction in a path of the re-closable strip, the second driving assembly configured to move the re-closable strip only and at a third forward movement speed towards the longitudinal sealing tool;
• and
• a transverse sealing and cutting tool arranged downstream of the forming tube in the forward movement direction and configured to transversely seal and cut the film tube such that the re-closable package is produced,
• wherein the first driving assembly comprises first and second rollers that face one other and the second driving assembly comprises first and second rollers that face one other, the first and second rollers of the first driving assembly being configured to rotate while respectively acting on the first and second longitudinal ends of the film to move the first and second ends of the film and the re-closable strip in the forward movement direction, the first and second rollers of the second driving assembly being configured to rotate while acting on opposite sides of the re-closable strip to move the re-closable strip in the forward movement direction,
• wherein the first and second rollers of the second driving assembly respectively include a first rotation shaft and a second rotation shaft, the first and second rotation shafts being rotationally connected to one another such that when one rotates so does the other, the first and second rollers of the first driving assembly respectively include a first rotation shaft and a second rotation shaft, the first and second rotation shafts of the first drive assembly being rotationally connected to one another such that when one rotates so does the other.
