本发明涉及适于通过浸渍浸渍沿处理路径（20）（10）上运行的纸幅（24），特别是装饰纸幅的浸渍设备（10），与至少一种树脂，浸渍（10）的传感器（30） 其适于在该过程中线路（20）的第一位置时，由通过浸渍（10）上运行的纸幅（24）以检测第一光谱信号，并且其中所述浸渍（10）计算装置（46）， 适于在由浸渍（10）来计算的特性的量度溢出从取决于纸幅（24），所述第一光学频谱信号。 本发明还涉及一种用于这种浸渍的监测的方法。

The invention relates to an impregnation (10), adapted for impregnating a along a process path (20) through the impregnator (10) running paper web (24), in particular decorative paper web, with at least one resin, the impregnation (10) a sensor (30) which is adapted at a first position in the process line (20) to detect a first optical spectral signal from the impregnator (10) running paper web (24), and wherein the impregnation plant (10) comprises calculation means (46), which are adapted to a measure of a property of the impregnation (10) overflowed paper web (24) to calculate a function of the first optical spectral. The invention also relates to a method for monitoring of such impregnation.
