    • An apparatus for coating a web (W) comprises a vacuum chamber (1) housing a metal vapour source (2) adjacent a driven water cooled process drum (5). The web (W) is drawn over the drum (5) during operating and deposition of metal on the web (W) is monitored and controlled. The monitor (6) may comprise transmitters (T1 to T10) and receivers (C1 to C10) disposed on opposite sides respectively of the web (W) or transmitters (T1 to T10) and receivers (C1 to C10) on the same side of the web (W). The first arrangement works on a signal transmitted through the web (W) and the second on a signal reflected from the web (W). Received transmitted or reflected signals are used to vary process variables to achieve desired coating thicknesses.
    • 用于涂布纸幅(W)的装置包括容纳邻近驱动水冷处理鼓(5)的金属蒸气源(2)的真空室(1)。 在操作期间将卷材(W)拉过滚筒(5),并且监测和控制卷材(W)上的金属沉积。 监视器(6)可以包括分别布置在卷筒纸(W)或发送器(T1至T10)的相对侧的发送器(T1至T10)和接收器(C1至C10),并且接收(C1至C10) 网(W)。 第一种布置工作在通过卷筒纸(W)传输的信号上,第二布置工作在从纸幅(W)反射的信号上。 接收的透射或反射信号用于改变工艺变量以达到所需的涂层厚度。
