Working rational and purpose:
Dual blades 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.
