用于将介质涂覆到移动的纤维料幅两侧上的设备和方法
摘要：
本发明涉及一种用于将液态或糊状的介质(2)涂覆到移动的纤维料幅(3)，尤其是纸幅、钞票纸幅、纸板幅或包装纸幅的两侧上的设备(1)，该设备具有第一涂布辊(5.1)和第二涂布辊(5.2)，所述第一涂布辊(5.1)和第二涂布辊(5.2)至少在所述移动的纤维料幅(3)的宽度上延伸并且形成具有辊导入区域(6)的辊隙(N)，所述移动的纤维料幅(3)能够被导引通过所述辊隙(N)，并且该设备具有用于将所述液态或糊状的介质(2)输入所述两个涂布辊(5.1.5.2)的辊导入区域(6)中的输送装置(7)，其中，在所述设备(1)运行时在所述两个涂布辊(5.1.5.2)的辊导入区域(6)中形成所述移动的纤维料幅(3)运行经过的料液槽(8)，并且借助所述辊导入区域能调节所述料液槽(8)的液位(9)。根据本发明的设备(1)的特征在于，从所述移动的纤维料幅(3)的幅面运行方向(L)看在所述料液槽(8)和所述辊隙(N)之前布置至少一个也容纳所述液态或糊状的介质(2)的浸浴设备(10)。
摘要（英）：

The invention relates to device (1) for applying a liquid or pasty medium (2) to a moving fibrous web (3), in particular a paper, bank note paper, cardboard, or packaging paper web, on both sides, comprising a first application roller (5.1) and a second application roller (5.2), which extend at least over the width of the moving fibrous web (3) and which form a roller gap (N) having a roller inlet area (6), through which roller gap the moving fibrous web (3) can be fed, and comprising a feed device (7) for feeding the liquid or pasty medium (2) into the roller inlet area (6) of the two application rollers (5.1, 5.2), wherein during the operation of the device (1), a liquid sump (8) is formed in the roller inlet area (6) of the two application rollers (5.1, 5.2), through which liquid sump the moving fibrous web runs, and by means of which feed device the level (9) of the liquid sump (8); can be adjusted. The device (1) according to the invention is characterized in that at least one immersion bath device (10) that also accommodates the liquid or pasty medium (2) is arranged upstream from the liquid sump (8) and the roller gap (N) as viewed in the web movement direction (L) of the moving fibrous web (3).
