  • Method and equipment in the measurement of the flatness of the flow surface of the headbox of a paper machine
    Patent number: 7335280
    Abstract: A method in the measurement of the flatness of the flow surface of a headbox of a paper machine is disclosed. The flatness is determined by placing a measuring tool on the flat surface formed by the flow surface and measuring the position of the measuring tool at each point. A measuring sensor is arranged in the measuring tool, in order to determine the distance between the measuring tool and the flat surface. In addition, the dimensions provided by the measuring sensors are read and the position of the measuring tool and the dimensions from the measuring sensors are combined, in order to determine the values of the measured points. The invention also relates to equipment in the measurement of the flatness of the flow surface of the headbox of a paper machine.
