  • Control equipment for the headbox tip lath in a paper machine or such and method of tip lath control
    Patent number: 6402893
    Abstract: Control equipment for the headbox tip lath of a paper machine includes first actuators (12a1, 12a2 . . . ), which are located at different points along the headbox (100) width and connect functionally with a bendable intermediate part (14). At the different points along the headbox (100) width there are also second actuators (13a1, 13a2 . . . ) which are used in the tip lath control. These connect functionally with both the bendable intermediate part (14) and the tip lath (11). The first actuators (12a1, 12a2 . . . ) are used to perform rough control of the tip lath (11) whereas the second actuators (13a1, 13a2 . . . ) are used to perform fine control of the tip lath (11).
