PM Speed Paper Machine Felt Paper Making Press Felt Of Paper Mill
Introduction:
Triple layer BOM press felts include the structures of 1 +2, 2 +1 and 1 +1 +1 composite felts. The press felts can be applied to more than 200 kN/m linear pressure and possess the features of good flexibility and permeability, excellent size stability, long life performance.
Triple layer press felts are used in high speed paper machines for suction complex press, large diameter nip roll press and shoe press to produce high grade news-prints, writing papers, paper-boards etc.
The felts are generally made of batt layer and fiber layer used for different PM. Each felt is customized for PM based on below data.
1. PM speed
