1. A large number of holes with a certain depth are drilled on the surface of the press roller, and the depth of the holes is best to use two or three different sizes of depth, the same arrangement. The bottom of the holes is not communicated with the atmosphere or vacuum, so it is called blind hole press. Blind press roll is composed of shaft head, roll body, roll shell and coating.
2. Blind press roller is composed of shaft head, roll body, roll shell and coating.
3. The air in the blind hole is compressed under strong pressure, and its volume is greatly reduced, remaining at the bottom of the blind hole. When the upper and lower blankets are pressed with the paper, the water in the blind hole is thrown out of the blind hole under the action of the centrifugal force of the high-speed rotary press roller, and is absorbed by the blanket. At the same time, the air at the bottom of the blind hole, due to the decompression effect of the pressure outlet area, It expands the volume of the air and bounces the water out of the blind hole, which is also absorbed by the blanket.
