Zusammenfassung:A vane intended for a headbox of a paper machine or equivalent is moistened and enclosed in a vapor-proof package to ensure the straightness of the vane. At least a portion of the vane is made of a water-absorbing material, such as plastic or a composite. Advantageously, the vane contains moisture in an amount that corresponds to the equilibrium moisture content of the vane in headbox conditions. It is enclosed in a package, preferably a vacuum package, which retains the moisture of the vane until the vane is put into use.
