ASTE-YSA Air-cell Dual Blades Device
Dualblades means using two air-cell blades at the same time. The purpose of the blade is to erase the water and the dirt on the roller surface. From a microscopic point of view, there are many uneven holes on the surface of the roller and the friction surface of the blade. While operating, the water and the dirt will run to the back of the blade through the holes. Though sometimes they can be taken away by the paper, most times, they stick on the back of the blade, and form a large mass. The drop of these masses will cause the break of the paper and the expensive stop of the machine. Especially on the stone roller on the press part, this problem is very serious. Apart from this, adding pressure on the blade will cause negative pressure on the back of the blade, which will cause piling dirt on the front of the blade and influence the quality of the paper.
The technique of dual blades is to solve this problem, which is to install No.2 blade at the back of No.1 blade, to scrape the dirt of the back of No.1 blade. |

ASTE - YSB
Make even and parallel touch between the blade and the roller through the air cell, to prevent from damaging the roller.
Through decompressing, adjust the air pressure to control the line pressure.
The thickness of the blade may range from 0.1mm to 6mm, 10,000-blade changing strategy.
The application of the ASTE-YSB blade device can effectively solve the balance of the three elements (line pressure, material and angel) and solve the problem of cleaning which is coming with the development of the paper making technology. |

ASTE - YSC
The most simple and widely used blade holder on the paper making machine.
Adding pressure depends on self weight, and generally manually lift and close the blade. But on some important occasions, we can temper the line pressure, lift the blade and add the pressure from long distance depending on the air tank. Such as, the blade used on the tension roller of the net part and the blade used on the paper falling cylinder on the drying part.
Temper the blade pressure through the micro adjusting screw. |

ASTE-YSD Creping Blade Device
The blade holder has step structure. The blade holder with obturation oil pressure tube can offer full breadth of soft touch between the blade and the roller, guarantee the firmness of the holder while touching and offer the high quality and steady crepe.
The blade is made of high standard spring carbon material. The blade has long life, and its friction degree ranges from 80 mm to 125 mm. |

Durable blade materials prolong normal operation time
The scraping function of the blade is getting more and more important when paper making machine is running faster and faster. It naturally demands blades functioning properly in every part of the paper making machine; only in this way can avoid expensive stopping and improve the production line efficiency and prolong the normal operation time.
To achieve the best scraping results, blade material must satisfy the demands of technology, consist with the property of the blade and have a certain duration and stiffness. And the blade's external form must adapt to the surface of the rollers to achieve the best shoveling and scraping result. The correct property of the blade ensures the best using effect on all production conditions.
EP blades range from composite blades, carbon fiber blades, and coating blades, repairing blades, blue steel blades, ceramic blades and polymer blades. We have a wide range of blades for your choice. We can meet any possible demand in paper making industry.
The basic technological principles of installing blade devices
The technological principles abided by in selecting blade material:
 Chilled iron casting roller cannot use stainless blades.
Chromium roller cannot use bronze blade.
Steel roller cannot use steel blade.
Copper roller cannot use metal blade.
Composite rubber roll cannot use metal blade.
Must change new blade before increasing blade pressure.
