Shoe press

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. The press roll has a bending compensation through a hydraulic system or a classic press roll with crowning.

Design

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. 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 upper 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 45 - 52 %.
