    摘要: A method for blowing steam against a paper web, whereby the steam is blown by a steam box having several profiling chambers in the cross direction of a paper machine. The cross-profile of the paper web is controlled by means of the steam supplied by the profiling chambers. A gas flow is provided between the profiling chambers to prevent the steam blown by a profiling chamber from affecting the effective area of the steam blown by the adjacent profiling chamber. Further, a steam box for implementing the method is disclosed.

    摘要: The measuring device is arranged to measure at least one property of a moving web. The measuring device includes at least one measuring head with at least one measuring element arranged in a flexible membrane that surrounds the measuring element and is arranged in connection with the measuring head such that the measuring element is movable by means of the flexible membrane perpendicularly to the moving web. The turning effect, which is caused by the pressure of the air conveyed with the moving web, and directed in the travel direction of the web at least in front of the measuring element on the web side of the flexible membrane, and turns the measuring element, is prevented by at least partly changing the amount and/or flow direction of the air conveyed with the web moving to the measuring element.

A sample is illuminated by a band of optical radiation the illumination state of which is variable as a function of time. Reference measurements of the spectrum of the optical band illuminating the sample are made at least at three separate instants of time. A spectrum of a band of the optical radiation that has interacted with the sample is measured at the corresponding separate instants of time as the reference measurement, and the radiance transfer factor matrix of the sample is estimated from the set of reference measurements and the set of sample measurements.
