<p>A method and an apparatus for wetting fibrous material, such as coarsely shredded waste paper. Fibrous material and wetting fluid is introduced into a wetting enclosure (10). Pressure is decreased within the wetting enclosure (10) for a short period of time for sucking out air from the fibrous material. Pressure is allowed to increase rapidly, whereby wetting fluid is sucked into cavities within the fibrous material and the material is efficiently wetted. <IMAGE></p> |
