A packaging machine comprises a conveying device for advancing a web along a web advancement path at least to a tube forming station where the web is formed into a tube and for advancing the tube along a tube advancement path, a tube forming and sealing device configured to form and to longitudinally seal the tube, a tensioning device upstream of the tube forming station and configured to control the tension of the tube and a control unit configured to control packaging machine operation. The tensioning device comprises a main drive roller rotatable around a main rotation axis and a main drive motor configured to actuate rotation of the main drive roller around the main rotation axis. The control unit is configured to control the main drive motor such that angular speed and/or angular acceleration of the main drive roller is cyclically varied to control the tension of the tube.

Packaging machine and method for producing sealed packages

A system for controlling a manufacturing process for packaging units is disclosed, the packaging units are manufactured from a packaging material comprising machine readable identifiers. A control unit associates the identifiers with corresponding data images of the packaging units, wherein for a first process application to manipulate packaging material based on a first set of process parameters, the control unit is configured to store at least part of the first set of process parameters to the associated data image, wherein for a subsequent second process application to manipulate said packaging material, read at least part of the first set of process parameters stored in said associated data image to control the second process application based on at least part of the first set of process parameters.
