WEB WINDING WITH FRICTION-BASED TENSIONING

A printing system comprises a transport path for transporting a web medium. The transport path comprises a slack region wherein the web medium is slack or substantially tension-free. A take-up roller is positioned at a downstream end of the transport path for receiving and winding the web medium. A...

Summary:A printing system comprises a transport path for transporting a web medium. The transport path comprises a slack region wherein the web medium is slack or substantially tension-free. A take-up roller is positioned at a downstream end of the transport path for receiving and winding the web medium. A tensioning device is positioned along the transport path between the slack region and the take-up roller. The tensioning device comprises a first surface arranged for exerting a friction force on the web medium moving over the first surface in a direction opposite to a transport direction of the transport path, such that the web medium is tensioned between the tensioning device and the take-up roller. Since the friction force tensions the web being wound onto the take-up roller, the wound media rolls are tightly wound when applying "loose winding".
