The pick up felt is mainly used for picking up the wet paper sheet from forming section to dryer section. The pick up felt play an important role in the pick up process, normally the paper machine pick up have three type methods is open type pick up, stick paper pick up, and vacuum type pick up.
The Impact of Forming Fabric on Printing Marks and its Solution These marks match the weave pattern of the forming fabric and can sometimes be found at the same angle on the paper. Forming fabric marks are generally caused by improper forming fabric selection or excessively fast dewatering speed (especially in the initial stage). Improper forming fabric selection requires contacting … Paper Machine Clothing Paper Imprints Problem Solve Method
how do contaminants accumulate on and inside press felt during operation, and how backside high-pressure spray systems remove embedded deposits to restore permeability and cleaning efficiency.
Analyzes forming fabric blockage in papermaking, including causes such as resin, fillers, and contaminants, and outlines effective cleaning and control measures to restore filtration performance.
Explains the causes of felt marks in papermaking, focusing on press felt structure, fiber layers, and operating conditions, with practical measures to control marks and enhance paper quality.
About installation preparation, gradual commissioning, and in-service care of forming fabric, highlighting how tension control, alignment, and cleaning affect service life, drainage efficiency, and run stability.
About three common press felt problems: steam spots, slurry penetration, and rewetting. Understand why each issue happens, how it affects paper production, and what actions can fix it.
Frequent wear on forming fabric can shorten service life and disrupt paper formation. Typical damage modes and operational factors affecting fabric durability are described.
Regular dryer fabric replacement is essential in papermaking. High heat, pulp, and chemicals cause fouling and wear, cutting drying efficiency and paper quality.
Press felt cleaning is crucial for dewatering efficiency, paper quality, and the life of the press felt itself. The main cause of the contamination is blockage by fiber fillers, slurry, resin and other impurities. Appropriate alkaline and acid washing can remove deposits and improve the dewatering efficiency of press felt.
