Fuction
1.Water filtering function:As a dehydration medium, when the paper sheet is dehydrated in the vacuum box and press area, the paper blanket absorbs and filters out the water from the paper sheet.
2. Leveling effect:In the process of web transfer and dehydration, it can smooth and modify the paper surface.
3. Function of conveyor belt:The paper is transferred from the net part to the drying shaft through the pressing part, and the passive roller and net cage are driven to run.Parameter

Reason of Felt Lint
There are many reasons for the damage and the lint of the felt, mainly two of which are scraped by machine parts and chemical damage.
1.The most common reason is that the surface of the press felt torn loosened by high pressure water.
2.Lack of lubricating water between the vacuum panel and the blanket, which causes the temperature rise and the fiber is damaged.
3.Material of Vacuum suction cover is bad,large in friction coefficient, the edges of the cover and the seam has burrs or with sharp blade shaped, without rounding out the edges,the wrap Angle between the vacuum box and blanket is too large, high vacuum degree, local surface irregularities,fixed screw exposed,the above will lead to blanket abrasion.
4.Supporting roller surface with burrs, iron molds , the roller surface wrapped with slurry, or expander roller rubber thread stand is too high or stand has obvious edges and corners,no sharp edges exists between eight openings and rubber roller body or the high and low transition zone is too short, etc are likely to cause felt abrasion .
