Product Description

The max. width of felt we can do 9.5m, the max. width of seam felt we can do 8.5m. We can provide profseeional felt for crescent,shoe and tissue paper machine. 
Speed: 800-2000m/minute

Function
  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.

Type

                            Single Layer BOM Felt
 Application:
    Paper machine: Cylinder Super, Forming, Fourdrinier, Inclined Wire Machine etc for forming section felt, press felt.

Advantage:
      Less elongation, easy to wash, no-mark on paper, long life performance etc. 
 

 

                              Double Layer BOM Felt
Application:
    Paper machine: Multi-cylinder, super forming, Superposition Wire for different kinds of paper machine press felt and forming felt.

Advantage:
    High-pressresistance, good flexibility, good permeability, good size stability.
 

 

                              Triple Layer BOM Felt
Application:
    Paper machine: Medium/high Velocity paper machine of Multi-cylinder,Superposition Wire,Vacuum Composite Press etc.

Advantage:
    Good flexibility; good permeability and can effectively eliminate many kinds of marks, excellent size stability, long life performance. 
 

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 .

Solution to Protect Felt
  1.The rational use of lubricating water now only benefit to the clean degree of the blanket but also produce a water film between the vacuum panel and felt which play a role as a lubrication, sealing and cooling effect.
  2.Vacuum panel slit between the two strips should be used the same material as the panel material or lower wear-resisting performance than the panel material. From the outside of the vacuum area from dense to sparse and with appropriate amount of lubricating water.
  3.All supporting roller surfaces should be smooth without burrs and rust,and copper rollers, stainless steel rollers and rubber rollers are options.
  4.There is a speed difference between the relevant transmission points, causing the felt to rub and wear out.Adjust the speed ratio of each transmission point correctly to avoid the abnormal speed difference.
