  • Patent number: 4799413
    Abstract: A cutting arrangement for the cutting to shape of a web-shaped material, such as paper webs (2) in printing presses. The arrangement consists of a cutting element (8) and a backing element (3) over which the paper web runs, in conjunction with which one edge of the cutting element (8) is brought intermittently into contact with the paper web for the purpose of cutting through the paper web in its longitudinal sense. The cutting element (8) is so arranged as to change its position intermittently in relation to the paper web (2) between a first, advanced position in which the cutting element (8) uses its edge to cut through the paper web as it passes over the backing element and a second, withdrawn position in relation to the paper web in which the cutting element is not in contact with the paper web. The intermittent movements of the arm between the first and the second position are controlled by a control unit (12) depending on the advance of the paper web (2).
