Wetting fibrous sheet, e.g. of paper or cardboard, in smoothing calender, by contacting with steam-water mixture having mixing ratio controlled in dependence on sheet parameter(s)

摘要

In a method for wetting a fibrous sheet (1) in a smoothing calender having several smoothing nips (at least one of which is heated), in which the sheet is wetted by contact with a steam-water mixture, the mixing ratio of the mixture is controlled in dependence on at least one sheet parameter.
