水印辊能整饰纸面,对提高纸张的物理性能、表面性能、适印性能均有明显的效果,尤其是改善纸张匀度、增强表面细腻有显著效果;另外还有一个重要的作用就是赋予纸张所需的水印。而生产不同类型的水印纸则需要不同的水印辊,在生产水印纸的长网纸机上一般一台纸机固定使用一个水印辊,因而生产品种单一,技术参数的调整范围有限。在此,提供一种能使用于生产不同类型的水印纸、也能生产非水印纸的长网纸机的网部装置。该装置采用活动支撑架,可以灵活安装不同直径的水印辊,以生 Watermarking roller can finish the paper surface, which has obvious effect on improving the physical properties, surface properties and printability of the paper, especially for improving the evenness of the paper and enhancing the fineness of the surface. Another important function is to give Watermark required for paper. The production of different types of watermark paper requires a different watermark roller, paperboard in the production of watermarked paper machine generally a paper machine fixed with a watermark roller, which produces a single species, the adjustment of the technical parameters of a limited range. Here, there is provided a net unit capable of being used in a fourdrinier machine that produces different types of watermark paper and also produces non-watermarked paper. The device uses an active support frame, you can flexibly install different diameter watermark roller, to students
