The blade tensioning device is disposed on a blade supporting beam extending transversely to the direction of movement of the web, the blade supporting beam swivelable and oscillatable transversely to the direction of movement of the web. The holder includes a supporting element and a stand having a bracket upon which a first drag bearing is disposed, the supporting element rotatably supported by the first drag bearing. A second drag bearing links the supporting element, the blade supporting beam, and a lever. The holder also includes a swiveling device for swiveling the blade supporting beam from a working position to a maintenance position and a positioning device for adjusting a blade working angle.
