Abstract

There is described a packaging machine (1) comprising a conveying device (5) for advancing a web (4) along a web advancement path (P) at least to a tube forming station (6) at which the web (4) is formed into a tube (3) and for advancing the tube (3) along a tube advancement path (Q), a tube forming and sealing device (10) configured to form and to longitudinally seal the tube (3), a tensioning device (32) arranged upstream of the tube forming station (6) and configured to control the tension of the tube (3) and a control unit (13) configured to control operation of the packaging machine (1). The tensioning device (32) comprises a main drive roller (33) rotatable around a main rotation axis (A) and a main drive motor (34) configured to actuate rotation of the main drive roller (33) around the main rotation axis (A). The control unit (13) is configured to control the main drive motor (34) such that an angular speed and/or angular acceleration of the main drive roller (33) is cyclically varied such to control the tension of the tube (3).
