发明名称 Method and equipment in connection with a paper machine or a paper web finishing apparatus
摘要 A variable representing runnability of a paper web to be manufactured with a paper machine or processed with a finishing apparatus is measured and the speed difference between operational groups of the paper machine and/or the finishing apparatus is adjusted on the basis of the measurement of said variable such that the moisture profile of the paper web is measured substantially along the entire width of the paper web, the minimum and maximum values for moisture are defined on the basis of the moisture profile, a drawing window describing the allowable tension to be directed to the paper web is defined, the lower and upper limits of the drawing window being defined on the basis of the minimum and maximum values for moisture, and the speed difference between the operational groups is adjusted so that the paper web tension is within the range defined by the drawing window.
