Blind hole press roller is another improved press roller developed on the basis of grooved roller in the 1970s. Blind hole press roller is also in the iron core roll rubber or polyurethane. Drilling surface covered with a hole diameter of 2mm, 12-15mm deep blind hole. Can also drill different shades of blind holes between two rows of white, blind hole press roller opening rate of about 25% to 30%, the eyelet volume than about 5 times the pressure roller, it can accommodate more press water.
In addition to the advantages of groove press roll,It also has four outstanding advantages：
1.It can make the moisture of wet paper uniform and reduce the blanket mark on the paper surface.
2.The water entering the blind hole can be thrown out by the compressed air after the pressure is released.
3.special bonding system ensures the safe operation under high speed and high linear pressure; 4.good wear resistance, effective dehydration,Stable hardness.
