Apparatus for wetting sheet of material, e.g. paper, comprises housing with liquid and gas supply connections and distribution chamber in which liquid is forced through porous material to give fine droplets

摘要

In apparatus (1) for wetting a sheet (2) of material, comprising a housing (3) with a liquid supply connection (4) and a sheet-facing wetting side (9) through which liquid is delivered onto the sheet, the liquid connection opens into a distribution chamber (7), also provided with a gas connection (8), and porous, liquid- and gas-permeable material (23) is located between the distribution chamber and the wetting side. An independent claim is included for a method for wetting a sheet of material by converting a liquid into droplets and transporting the droplets onto the sheet, where the liquid is pressed through a porous material using a gas.
