Paper Forming Machine Vacuum Couch Roll
The vacuum couch roll is a vital component in the forming part of a paper making line. It helps remove water from the wet paper web and transfers the sheet smoothly to the press section. By using vacuum suction, the vacuum couch roll keeps the paper web intact and reduces the chance of breaks. A high-quality vacuum couch roll ensures stable operation and improves the overall efficiency of your paper production line. It is a key piece of paper mill machinery that directly affects the final paper quality.
Our vacuum couch roll is built with a robust design and high-quality materials. The vacuum box and internal parts of the vacuum couch roll are made from welded 304 stainless steel. The sealing system of this vacuum couch roll uses air tube pressing with wear-resistant mixed material seal strips to ensure strong and stable suction. The suction angle of the vacuum couch roll can be easily adjusted through a worm gear on the operating side. The operating side panel is equipped with quick-change pipe connections, a stainless steel vacuum gauge, a stainless steel pressure gauge, and a manual stainless steel vacuum control valve. The vacuum couch roll also features a wetting shower pipe and a dual-chamber design with an edge-suction box.
