Shoe press is located in the PM press part. It belongs to the group of presses with an extended pressing zone. The load is controlled from 0 kN/m to the maximum load up to 1,200 kN/m.
The press roll has a bending compensation through a hydraulic system or a classic press roll with crowning. The shoe press is equipped with a stationary beam on which a set of hydraulic cylinders is attached. These cylinders press down the “shoe” to the rotating flexible blanket.
The shoe profile is influenced by the shape of the loading roll. A rotating elastic blanket of the lower roll slides over a thin oil layer. Because of the hydraulic cylinders set and hydraulic unit design, it is possible to control the cross profile of the paper. It is used as a final press that is able to reach 35 – 40 % dryness when the dryness at the entrance is about 48 – 52 %.
