Control equipment for the headbox tip lath of a paper machine includes first actuators ( . . . ), which are located at different points along the headbox ( ) width and connect functionally with a bendable intermediate part ( ). At the different points along the headbox ( ) width there are also second actuators ( . . . ) which are used in the tip lath control. These connect functionally with both the bendable intermediate part ( ) and the tip lath ( ). The first actuators ( . . . ) are used to perform rough control of the tip lath ( ) whereas the second actuators ( . . . ) are used to perform fine control of the tip lath ( ).
