Papermaking PAPERMACHINE PRESSING 1.

Hydraulic pressure in the area of paper facing the felt is almost identical to the total hydraulic pressure in the felt. Hydraulic pressure will then grow with the distance from the felt surface and be the highest at the roll. This means that the forces compressing the fibre structure will be largest close to the felt.

How Does a Hydraulic Arm Work? Reference

A hydraulic arm works by using high fluid pressure, created by a pump, to force a piston in a cylinder to move. As a valve is opened one way, the fluid is allowed to enter the cylinder and force the piston to move. An example of a typical hydraulic system would be a three-way valve operated by a lever. In the central position, the valve is closed.
