Paper Machine Press Felt
Paper machine press felt is important for removing water of paper sheet in paper machine press section, and it has some properties to ensure work efficiency.
Generally, paper machines operate with little attention required of the vacuum processes. Yet these systems tend to evolve into processes with lost performance. The result is often reduced dewatering capability, which has a direct and negative impact on paper machine efficiency and operating costs. Other problems can include vacuum pump reliability and maintenance problems contributing to downtime.
The press felt plays an important role in removing the water from the paper web after the forming section, and at the same time imparting smoothness and conveying it to the dryer section. For this reason, the press felt needs to provide the following functions: Water removal, smoothness and runnability. In recent years, larger and faster paper machines require press felts of even higher consistency and quality.
