    • The invention relates to a method for coating a fibrous web with one or more layers of coating. The method comprises applying at least one layer of a coating material to the surface on at least one side of a fibrous web (W) by means of a curtain coater (21), and that a still moist coating of the applied layers of coating material is subjected, essentially immediately after said application process, to a hot compression contact by means of a hot contact surface or contact surfaces, the coating bonding to the fibrous web's (W) surface, the coating drying and its surface becoming smooth and glazed. The invention relates also to an apparatus (2) for coating a fibrous web (W). The apparatus comprises at least one curtain coater (21) for applying at least one layer of coating material onto a surface of the fibrous web (W), as well as a treatment unit (22) substantially immediately downstream of said curtain coater in the fibrous web's (W) traveling direction for treating the fibrous web (W) in a hot compression contact.
    • 本发明涉及用一层或多层涂层涂覆纤维网的方法。 该方法包括通过帘式涂布机(21)在纤维网(W)的至少一侧上的表面上施加至少一层涂料,并且涂覆材料涂层的静止涂层 基本上在施加过程之后立即通过热接触表面或接触表面进行热压接,涂层粘合到纤维幅材(W)表面上,涂层干燥及其表面变得光滑和上光。 本发明还涉及一种用于涂覆纤维网(W)的装置(2)。 该设备包括至少一个帘式涂布机(21),用于将至少一层涂料施加到纤维幅材(W)的表面上,以及基本上在所述帘式涂布机的下游的纤维状物料 幅材(W)行进方向,用于在热压缩接触中处理纤维幅材(W)。
