  • PACKAGING MACHINE FOR PRODUCING SEALED PACKAGES
    Publication number: 20220177173
    Abstract: A packaging machine comprises a conveying device for advancing a web along a web advancement path at least to a tube forming station at which 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 longitudinally seal the tube, a tensioning device upstream of the tube forming station and configured to control tension of the tube and a control unit configured to control operation of the packaging machine. 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 controls the main drive motor such that an angular speed and/or angular acceleration of the main drive roller is cyclically varied to control tension of the tube.
