The air spring is located in different areas of the paper production process. Air springs consist of a flexible elastomer rubber body with nylon fabric reinforcement, and rustproof plates with an air inlet and mounting blind nuts. The rubber bellows can be used both as vibration isolators and rubber actuators. The air springs absorb up to 99% of the unwanted vibrations avoiding further damages to the machines and metallic structures. At the same time, they reduce noise level.

The Air springs are applied in different kind of applications in paper mills, where we can see the different functions that the air actuator provides in different parts of the paper manufacturing process:
1.Air spring used as an edge control system to align the bandage that carries the paper.
2.Tenses the web that carries out the paper.
3.Used as a press, to extract the humidity from the paper with the rollers located in the machine.

One requirement of air springs for paper machine is shock absorption and the other is stroke control.
By adjusting the compressed air pressure into the air spring, the height of the air spring decreases, the volume of the inner chamber decreases, the stiffness of the spring increases, and the effective bearing area of the air column in the inner chamber increases, and the bearing capacity of the spring increases. When the vibration load decreases, the spring height increases, the cavity volume increases, the spring stiffness decreases, the effective bearing area of the air column decreases, and the bearing capacity of the spring decreases.

In this way, the height of air spring, the volume of inner cavity and the bearing capacity of air spring have smooth flexible transmission and high efficiency control of amplitude and vibration load with the increase and decrease of vibration load. The stiffness and bearing capacity of the spring can also be adjusted by increasing or decreasing the air charge.

1.Lower cost;
2.Maintenance cost savings, no moving parts, no sealing parts, no friction between parts;
3.No mantenance or lubrication required;
4.Reduced space requirement;
5.Angular capability.
